CUMMINGS, Circuit Judge.
In June 1969, appellant Frederick Chase and ten others were indicted for destroying government property, mutilating government records,, interfering with the working of the Selective Service Act by force and violence, and conspiracy to commit those three offenses. After a lengthy jury trial, Chase was found guilty on all four counts. He was sentenced to five years’ imprisonment on Counts III and IV, to run concurrently; as to the remaining two counts, he was placed on probation for five years eommencing with the expiration of the other sentences.
When the trial of the eleven defendants commenced on May 6, 1970, Chase refused to stand when the trial judge entered the courtroom, and he continued to do so whenever the judge or the jury entered or left the courtroom during the trial.
At the opening of the afternoon session on May 8, Chase’s counsel read into the record a note from Chase explaining his refusal to rise. This note reads as follows:
“The Bill of Rights provides for freedom of religion. While my religious beliefs may not be conventional in terms of religion, I still feel that they have to be followed in order to follow the dictates of my conscience. The First Commandment states, T am the Lord, thy God. Thou shall not have false gods before me.’
“My religious belief, if the Judge or anyone cares to call it that, defines God as collection of living things. While I can participate in actions of respect toward human beings, I cannot participate in actions of respect toward institutions which would indicate a superiority of the institutions over human beings. In conventional religious terms I cannot place false gods before the true God. By requiring that I stand, Mr. Robson is violating my right to religious freedom and also requiring that I violate my conscience. I would appreciate it if you would attempt to explain this as soon as possible.”
Chase then told the court:
“I have no qualms about standing for you as a man; I respect you as a human being. It is just that I can’t stand for institutions.
“I feel the same way for the jury. I intend no disrespect for them as human beings, but I can exercise no respect for them as jurors, because I do feel that that violates my conscience. If you are — if you could just say to [130]*130me that you understand that I would be standing to you as a human being, and not as a judge, I would be willing to do so.”
In response, the judge stated:
“Now I am not asking that you stand for me; I am asking that you stand for the courts which are a part of our whole system of government within this country.
“I took a solemn oath when I was sworn in as a judge to uphold all of those standards, including those of the Constitution, and I do not intend to allow one individual or individuals to attempt to break that down.
“Now when you stand, you will be standing to the courts of this country, not for me. I am just a human being, as you are, but I am dealing with institutions.
“Unless you agree to stand, you offer me no alternative but to hold you in contempt of court.
“I have a list of all of the times.
“Now if you will agree to stand, not to me as an individual, but as to the courts, then we will have no problems.
“But if you refuse, you give me no alternative but to exercise the powers that are given to me for carrying out my responsibility as a Judge of the United States District Court.”
Thereafter, the following colloquy occurred between the court and Chase:
“THE COURT: ■ Now I ask you now whether or not you will stand not when I come in as an individual, but for me as á representative of the court system, and for the jury as a representative of the court system?
“If you will promise me that you will, we will have no further problems.
“If you refuse to do so, then you will give me no alternative.
“I ask you what your attitude is.
“DEFENDANT CHASE: Well, sir, I am attempting to follow the dictates of my conscience, and I feel that those dictates have priority over the dictates of the State. And I am afraid that I have to say that I can’t stand.
“THE COURT: All right now let me state this to you, Mr. Chase, that it is not just for this one offense, it will be a continuing one. Every time you fail and refuse to stand, then I will have no other alternative but to hold you in civil contempt.”
Subsequently Chase advised the court that he did not belong to any formal religion but was “from a catholic background.” He said that since the community of man was his god, he could not place anything above his respect for human life and therefore could stand for the trial judge only as a man rather than as a judge.
The court then announced that it would not impose any contempt sentence for May 6 or 7, but that since Chase had already been warned on May 7, it was imposing a 20-day civil contempt sentence for the eight refusals to stand when the court and jury came in on May 8. The judge explained that Chase would not have to commence serving the 20-day sentence until the end of the trial.1 He then stated,
“Now, if you continue to flaunt your responsibility as a citizen of this country, I am going to continue to impose contempt citations, and I ask you to think of that.
“If you tomorrow morning, or Monday morning, when Court opens, will come in and promise to observe the proceedings in this Court, I will consider that in connection with it.
“I will give you that opportunity to think of it. You may purge yourself of contempt, or the Court has no other alternative than to impose sentences. Do you understand that ?
“DEFENDANT CHASE: Yes, sir.”
At the close of the proceedings on May 15, Chase again explained his attitude, stating:
“I think I have made my position fairly clear on the reason why I do [131]*131not feel I can rise. I understand that you are trying to uphold the law, as you understand it. I am trying to uphold the right as I understand it. I have discovered that the two often come in conflict, but as long as I have the strength, I will have to stand by the right rather than the law.”
During the course of the trial and at its conclusion, a total of five certifications of criminal contempt for persistence in ’refusing to stand on the entrance of the court or jury were read to Chase pursuant to Rule 42(a) of the Federal Rules of Criminal Procedure.2 The first certification was rendered on May 11 and was accompanied by the following prefatory remarks:
“Pursuant to Rule 42(a), Federal Rules of Criminal Procedure, the court finds that the defendant Frederick Joseph Chase has committed certain contemptuous acts in the actual presence of the court. The defendant Chase has refused to rise for either the court or the jury at 'the opening and adjournment of each and every session of the court.
“The record reflects that the court has brought this matter to the defendant Chase’s attention on several occasions, and warned him that continuation of such conduct would be punished as criminal contempt. At the opening of court on Friday afternoon, May 8, 1970, the court admonished the defendant Chase that his misconduct was a manifestation of contempt not for the court personally but rather indicated his contempt for the judicial process and the courts of the United States. The court then advised the defendant Chase that he would be given the opportunity to reconsider his conduct and purge himself of any and all previous acts of contempt. Following the court’s admonition, however, the defendant Chase has refused to rise on each and every occasion when so directed by the court through the Deputy United States Marshal. The court therefore adjudges the defendant Chase to be in direct, criminal contempt of this court and imposes the following sentences: ”
In the first certification of contempt,, 3-day consecutive sentences were imposed for seven refusals to rise when the court or jury entered the courtroom on the afternoon of May 8 and again on May 11. The second certification of contempt occurred on May 15 and covered eleven similar refusals to rise, again resulting in 3-day sentences consecutive to those imposed on May 11. The third certification, handed down on May 19, covered 15 later identical con-tempts, resulting in a 45-day consecutive sentence; the fourth certification, rendered May 21, covered 13 later con-tempts resulting in a 39-day consecutive sentence; and the final certification, given at the close of the trial on June 9, covered 53 similar refusals to rise, again resulting in 3-day consecutive sentences for each. Together the five certifications covered 99 identical acts of contempt,3 resulting in a total sentence of 297 days to be served prior to the 5-year prison term imposed upon conviction of the offenses for which he was indicted.
Chase first contends that the certifications of criminal contempt must be vacated because his refusals to rise do not constitute misbehavior obstructing the [132]*132administration of justice within the meaning of the contempt statute.4 We ruled to the contrary in United States ex rel. Robson v. Malone, 412 F.2d 848, 850, stating that the rising “requirement is sufficiently related to maintaining order in the actual presence of the court, so that an infraction can be dealt with summarily under Rule 42(a) * * *.”5 As we pointed out, “the traditional rising in unison of persons present in a court can reasonably be thought to contribute to the functioning of the court. It is a way of marking the beginning and end of the session, and probably serves to remind all that attention must be concentrated upon the business before the court, the judge’s control of the court room must be maintained with as little burden on him as possible, and there must be silence, except as the orderly conduct of business calls for speech.” In United States v. Seale, 461 F.2d 345, 369 (7th Cir. 1972), we ruled that the contempt statute contemplates an actual, material obstruction. Contemporaneously in In the Matter of Del-linger, 461 F.2d 389, 401 (7th Cir. 1972), we reaffirmed the Malone conclusion, as applied to defendants in a criminal trial,6 that the judge “may require such rising” at the beginning of a session and end of a recess, and we did so fully cognizant, though unconvinced, by the type of approach espoused wholesale by the dissent. Id. and n. 10. Failure to rise could well constitute an actual and material obstruction to judicial administration although a mere refusal to rise does “not necessarily alone amount to obstructions punishable as criminal contempt.” Id.
Because of Chase’s behavior throughout the trial, various colloquies ensued between the judge, Chase and his counsel. On each of the occasions involved here the district judge would ask the deputy marshal to see that Chase stood up or to assist him to his feet. The judge would then note the refusals to rise on the record. At four intervals during the trial, he read four of the resulting citations of contempt to Chase. The fifth was read at the end of the trial. We consider that these various episodes necessitated interrupting the trial proceedings sufficiently to amount to obstructions of judicial administration within the meaning of the criminal contempt statute. See Comstock v. [133]*133United States, 419 F.2d 1128, 1131 (9th Cir. 1969).7
The Government asks us to hold that every failure to rise amounts to a sufficient obstruction of judicial administration on the basis that “the violation of a rule related to the orderly administration of justice creates per se obstruction.” Otherwise, the Government argues, “the determination of the offense would not rest on the wrongful character of the conduct, but upon the resulting reaction of the judge.” Had we accepted the Government’s argument in Dellinger, supra, we certainly would not have stated that a mere refusal to rise, without more, does not necessarily obstruct the administration of justice. 461 F.2d at 401. A participant’s or spectator’s defiance in the face of the court’s insistence on his rising can supply the requisite obstruction because the judge properly “may require such rising.”8 But even without any reaction by the judge, the failure to rise may amount to an actual and material obstruction if, for instance, as is quite likely, it distracts others in the courtroom or provokes a reaction on their part or is accompanied by a failure to become silent or focus attention on the business before the court. Pursuing the Government’s argument to its logical absurdity, if a person in the last row of seats, not noticed by spectators seated farther forward or participants, simply refuses to stand on the bailiff’s request but is intent on the proceedings about to start, and he is merely noticed but not then even addressed by the judge, we would have to find'an obstruction of judicial administration. We are loath to adopt a rationale with this result. The contempt statute requires something more tangible, though not always physical, in the way of an obstruction. See Judge Kaufman’s cogent analysis in United States v. Meyer, Slip Op. at 9-10 (D.C.D.C.Crim.Case No. 872-69, Misc. No. 28-72, decided July 28, 1972). However, we do note the long-standing tradition of rising out of respect for the court as well as its functional justification; thus refusal to abide by it may be viewed as not insignificant misbehavior. And as we stated in Seale, “the seriousness of the misbehavior bears on what conduct may be found materially obstructive.” 461 F.2d at 369. Suffice it to say again, the refusals to rise in direct defiance of the judge’s orders here could properly be found materially obstructive. United States v. Seale, supra at 371. We have no occasion to determine whether a sufficient obstruction could have been found absent the judge’s insistence that the appellant comply with the rising requirement.
[134]*134 Chase also argues that his refusals to rise were protected by his religious belief. According to that belief, appellant maintains he could not stand for the judge or jury as institutions, and the judge’s insistence that he rise for the institutionalized courts violated his freedom of religious exercise guaranteed by the First Amendment. Although the trial judge’s apparent insistence that appellant’s rising would signify respect to institutions was perhaps unnecessary since, as a practical matter, allowing appellant to stand for his own reasons may have alleviated the problem, we cannot take appellant’s argument seriously. This is because he has consistently admitted his willingness to rise for reasons of his own. His conscience, he said, would not have been offended by rising for the judge and jury as human beings. Moreover, he has never claimed that his religious belief required him initially to inform the court of the only signification he could give his standing, nor has he ever claimed that belief necessitated his forcing the judge to acknowledge the meaning of his rising. In the absence of any scruple at rising per se or any claim that his conscience required him to externalize his beliefs and secure the court’s acquiescence, no legitimate First Amendment question is presented. In any event, we would reiterate our holding in Malone, supra, 412 F.2d at 850, that the First Amendment does not excuse performance of the rising requirement. See also Stein v. Oshinsky, 348 F.2d 999, 1001 (2d Cir. 1965); Evans v. Ciccone, 377 F.2d 4, 6 (8th Cir. 1967).
Chase next asserts that under Bloom v. Illinois, 391 U.S. 194, 88 S.Ct. 1477, 20 L.Ed.2d 522, and its progeny, he was entitled to a jury trial of these contempts in that a total sentence of 9 months and 27 days was imposed, whereas summary adjudications of contempts are only permissible where the penalty imposed does not exceed 6 months’ imprisonment. This argument would be persuasive if the trial judge had waited until the conclusion of the court proceedings to cite Chase for all his foregoing contemptuous conduct. In United States v. Seale, 461 F.2d 345, 352-356 (7th Cir. 1972), we held that where the trial judge does not cite for contemptuous conduct immediately upon its occurrence but waits to act until the conclusion of the proceedings, consecutively imposed sentences for that conduct must be cumulated to determine the contemnor’s right to a jury trial. Here the trial judge did not cite appellant immediately upon his refusal to rise. However, rather than waiting until the end of the trial to find him in contempt for all his previous failures to rise, in which case an aggregate sentence of 9 months and 27 days would require the impanelling of a jury, the trial judge adjudicated appellant in contempt and pronounced sentence periodically four times during the trial and once at its end. All the theory of the aggregation rule announced in Seale requires is that the consecutive sentences imposed on each of the five certifications of contempt be cumulated to determine the necessity for impanel-ling a jury with respect to any of the five findings of contempt. Since none of the five citations carried an aggregate sentence greater than 6 months’ imprisonment,9 no jury was required to determine appellant’s guilt for the conduct charged in any of them.
The aggregation rule announced in Seale is partly justified as a protection against circumvention of the right to jury trial through a belated, arbitrary singling out of discrete instances of contempt from preceding disruptive conduct. The rule affords fuller protection than the necessarily imprecise appellate review of the trial judge’s discreteness determination. United States v. Seale, supra, 461 F.2d at 353-354. Neverthe[135]*135less, especially where as here the cited conduct consists of a repetition of a single contemptuous act, immediate citation and punishment not in excess of 6 months upon each instance or periodic citation with a 6-month or less total punishment each time may still improperly deny the contemnor a jury trial if it oppressively converts a single continuing offense into a series of individual ones. But contrary to the situation where a witness refuses to answer a spate of similar questions on Fifth Amendment grounds, where transparent proliferation of contempts is often found, here there was no opportunity for “prosecutors, by their sheer ingenuity in conceiving and stamina in asking multiple questions calling for slightly different answers, * * * to proliferate offenses.” Baker v. Eisenstadt, 456 F.2d 382, 390 (1st Cir. 1972);10 see Yates v. United States, 355 U.S. 66, 73, 78 S.Ct. 128, 2 L.Ed.2d 95. Rather, the long-standing rule of court procedure that the persons in the courtroom rise upon the entrance of judge and jury was not contrived nor could here have been manipulated to multiple the offense of refusal to rise.11 Even if we could properly compare appellant's refusals to rise to a witness’ refusals to answer successive, similar questions on Fifth Amendment grounds, this record does not show that Chase would assuredly continue tp adhere to his initial refusal to stand, especially since he admitted to being able conscientiously to stand for his own reasons and never claimed his religious belief required more than the proper interior disposition. See Yates v. United States, supra 355 U.S. at 73-74, 78 S.Ct. 128; Baker v. Eisenstadt, supra 456 F.2d at 393.12
Finally, there is nothing ineluctable about whether Chase’s refusals be viewed as a single offense or separate infractions, but the contemnor’s merely positing a common reason for his refusals is not alone enough to make his offense singular. Viewing them separately is rather natural, and we will not upset the trial court’s so seeing them.
Since the judge’s initial imposition of a 20-day sentence for civil contempt had been unsuccessful, it was permissible for him to resort to the criminal contempt route. See Illinois v. Allen, 397 U.S. 337, 344-345, 90 S.Ct. 1057, 25 L.Ed.2d 353; Yates v. United States, supra 355 U.S. at 74-75, 78 S.Ct. 128. Chase urges though that it was improper for the court to employ the summary disposition procedure of Rule 42 (a) of the Federal Rules of Criminal Procedure.13 That rule authorizes summary action if, as here, the judge saw the conduct constituting the contempt and if it was committed in the actual presence of the court. Harris v. United States, 382 U.S. 162, 86 S.Ct. 352, 15 L.Ed.2d 240, is of no avail to appellant, for there the real contempt occurred before the grand jury, and the majority [136]*136opinion viewed the bringing of the witness into court and the repetition of the questions before the judge as fashioned “to have the refusal to testify ‘committed in the actual presence of the court’ for purposes of Rule 42(a).” Id. at 164, 86 S.Ct. at 354. The present case is not one wherein Rule 42(a) proceedings are inappropriate because the contemptuous conduct involved an insolent, personal attack on the trial judge which disqualified him from adjudicating the contempt post-trial. Mayberry v. Pennsylvania, 400 U.S. 455, 91 S.Ct. 499, 27 L.Ed.2d 532; United States v. Seale, supra 461 F.2d at 351-352; In the Matter of Dellinger, supra 461 F.2d at 392-395. The appellant's conduct did not require the trial judge to recuse himself from pronouncing the contempt judgment. See Ungar v. Sarafite, 376 U.S. 575, 583-588, 84 S.Ct. 841, 11 L.Ed.2d 921. Although some question arises as to whether the trial judge may in every case not involving embroilment or personal attack proceed summarily to convict for contempt after the termination of the trial (see Groppi v. Leslie, 404 U.S. 496, 506, 92 S.Ct. 582, 30 L.Ed.2d 632; Ungar v. Sarafite, supra 376 U.S. at 589, 84 S.Ct. 841; United States v. Meyer, 149 U.S.App.D.C. 212, 462 F.2d 827, 843 and n. 25 (1972)), here the trial judge was well within his rights in proceeding under Rule 42(a) to punish these contempts. First of all, this is not a case where the judge acted only at the close of the proceedings; four times during the course of the trial summary proceedings were had as well as at its end. Moreover, the judge explicitly warned Chase at the outset that his refusals to rise were regarded as contumacious and that he would be later called to account. Importantly, the judge engaged in lengthy colloquy with the contemnor, allowing him fully to explain the purpose and motive of his refusals; each time a contempt judgment was pronounced, the judge took pains to give appellant an opportunity to speak in his behalf.14 The appellant was accorded due process. Cf. Groppi v. Leslie, supra 404 U.S. at 506, 92 S.Ct. 582.
Finally, Chase asks us to shorten the 10-month sentence imposed. In Malone, supra, we reduced the ten and thirty day sentences of confinement to the few hours the contemnors were held in custody before being released on bond by this Court. In our judgment, because this case involved at least 99 refusals to rise and a stubborn disregard of reiterated judicial commands, a total sentence of 30 days for Chase’s misbehaviors was justified but, under the circumstances, not more. Consequently, the 5-year imprisonment must be deemed to have commenced running immediately after the first 30 days served for these contempts.
Apart from the reduction in the contempt sentences to a total of 30 days, the judgments of conviction under 18 U.S.C. § 401(1) are affirmed.
