OPINION
ROBERTS, Justice.
At about 11:30 p. m., March 2, 1974, an altercation broke out between two rival gangs after members of one gang [322]*322arrived at a party attended by members of the other. During the fighting which followed John Alicea received a fatal knife wound in the chest. Appellant, Whalen Laws, Jr., was charged with the murder. Following a jury trial, appellant was convicted of murder of the second degree. Post-verdict motions were denied, and appellant was sentenced to seven to twenty years imprisonment. In this appeal,1 appellant contends that the trial court, by its questioning of a witness and by its warning the witness of the consequences of perjury, improperly pressured the witness to change his testimony. We agree,2 reverse judgment of sentence and grant appellant a new trial.

During the presentation of the prosecution’s case, Coy Coley III was called as a witness. Unexpectedly, Coley gave testimony favorable to the defense. In his testimony, he indicated that the person who stabbed the victim was not in the courtroom.3 At appellant’s preliminary hearing Coley [323]*323had identified appellant as the person who stabbed the victim.4
Over defense objection, the court questioned Coley in the presence of the jury about his testimony that he did not see the perpetrator in the courtroom.5 The court then excused [324]*324the jury, and the prosecutor read Coley his testimony from the preliminary hearing. The court asked Coley if he recalled his prior testimony. Coley said he did. The court then asked Coley if he was afraid of anything on the day of trial, or if anything else was preventing him from telling the truth at trial. After Coley responded that there was nothing preventing him from telling the truth, the court, over defense objection,6 warned Coley of the consequences of perjury.7 The court then asked Coley if there was anything preventing him from telling the truth at trial, and asked Coley if any threats or promises had been made to induce him to testify untruthfully. Coley again answered no. The court asked Coley, twice, if he was telling the truth at trial. Coley answered both times that he was telling the truth. The court then asked Coley if he was saying that his testimony at the preliminary hearing was not truthful, and asked him if he wanted to read his testimony from the preliminary hearing again.
After Coley read his testimony from the preliminary hearing, the court again asked him if he was under any threats or pressure to testify as he did before the jury. Coley again answered no. The court then asked Coley, over defense objection, if what he told the jury was the truth and if he [325]*325wanted to change that testimony now that he had read the notes of the preliminary hearing. Coley answered that he did not want to change his trial testimony. The court asked Coley, two more times, if he still maintained that his trial testimony was correct. After Coley answered affirmatively for the second time, the court asked Coley again if he wanted to change his trial testimony in any way. Coley said he did not. Before the jury was called back in, the court again warned Coley of the consequences of perjury.8
The Commonwealth then was allowed to cross-examine Coley in the presence of the jury, and the prosecutor read Coley his testimony from the preliminary hearing.9 Coley recanted his trial testimony and adopted his testimony from the preliminary hearing identifying appellant as the person who stabbed the victim.

In presiding over trial, the court has a paramount duty to maintain its impartiality, as well as a responsibility to respect the dignity of the witnesses. The court’s power to question a witness, and to warn the witness of the consequences of perjury, should be used sparingly, and with great circumspection.10 Efforts to clarify conflicting testimony [326]*326should normally be left to counsel, and the resolution of any conflicts should be left to the jury. When the court intervenes in this process, it may unduly influence the witness to shape his testimony to what the witness believes the court expects. Cf. Commonwealth v. Myma, 278 Pa. 505, 508, 123 A. 486, 487 (1924) (“It is better to permit counsel to bring out the evidence and clear up disputed points on cross-examination unaided by the court . . . . The practice of a judge entering into the trial oí a case as an advocate is emphatically disapproved.”).
In Commonwealth v. Myma, Justice (later Chief Justice) Kephart stated for this Court:
“The judge occupies an exalted and dignified position; he is the one person to whom the jury, with rare exceptions, looks for guidance, and from whom the litigants expect absolute impartiality.”
Id. Thus, the court may not question a witness in a manner which conveys to the jury the court’s opinion on the merits, or doubts as to the credibility of the witness. Commonwealth v. Williams, 468 Pa. 453, 364 A.2d 281 (1976) (plurality opinion); Commonwealth v. Butler, 448 Pa. 128, 291 A.2d 89 (1972) (dictum); Commonwealth v. Myma, supra. The need to maintain impartiality also demands that the court exercise its authority with care, and refrain from questioning which may pressure a witness to testify in a particular way.
A review of the record convinces us that the trial court’s questioning of Coley and the use of perjury warnings unduly pressured Coley to retract the testimony he initially gave at trial, and to adopt his testimony from the preliminary hearing. The court’s questioning clearly conveyed the impression that the trial court did not believe Coley’s trial testimony, and that Coley should adopt his testimony from the preliminary hearing. The court asked Coley five times if he was telling the truth at trial. The court repeatedly [327]*327asked Coley if any threats or promises caused him to testify falsely at trial, and asked Coley three times if he wanted to change or correct his testimony at trial. The court did not ask Coley if any threats or promises caused him to testify falsely at the preliminary hearing, or give Coley the opportunity to explain why he testified as he did at the preliminary hearing. The witness could have little doubt as to which testimony the court believed. The court’s questioning, coupled with the use of perjury warnings, improperly pressured the witness to change his trial testimony to conform with his testimony at the preliminary hearing.
The Commonwealth argues that the court’s action was harmless beyond a reasonable doubt. We cannot agree. Initially, Coley gave testimony favorable to appellant, indicating that someone other than appellant committed the killing. After extensive questioning by the court and admonishment on the consequences of perjury Coley retracted his earlier testimony and testified that he saw appellant stab the victim.
The Commonwealth relies on the testimony of two other witnesses. The first witness, Phillip Yant, testified that he saw appellant approach the victim.

In presiding over trial, the court has a paramount duty to maintain its impartiality, as well as a responsibility to respect the dignity of the witnesses. The court’s power to question a witness, and to warn the witness of the consequences of perjury, should be used sparingly, and with great circumspection.10 Efforts to clarify conflicting testimony [326]*326should normally be left to counsel, and the resolution of any conflicts should be left to the jury. When the court intervenes in this process, it may unduly influence the witness to shape his testimony to what the witness believes the court expects. Cf. Commonwealth v. Myma, 278 Pa. 505, 508, 123 A. 486, 487 (1924) (“It is better to permit counsel to bring out the evidence and clear up disputed points on cross-examination unaided by the court . . . . The practice of a judge entering into the trial oí a case as an advocate is emphatically disapproved.”).
In Commonwealth v. Myma, Justice (later Chief Justice) Kephart stated for this Court:
“The judge occupies an exalted and dignified position; he is the one person to whom the jury, with rare exceptions, looks for guidance, and from whom the litigants expect absolute impartiality.”
Id. Thus, the court may not question a witness in a manner which conveys to the jury the court’s opinion on the merits, or doubts as to the credibility of the witness. Commonwealth v. Williams, 468 Pa. 453, 364 A.2d 281 (1976) (plurality opinion); Commonwealth v. Butler, 448 Pa. 128, 291 A.2d 89 (1972) (dictum); Commonwealth v. Myma, supra. The need to maintain impartiality also demands that the court exercise its authority with care, and refrain from questioning which may pressure a witness to testify in a particular way.
A review of the record convinces us that the trial court’s questioning of Coley and the use of perjury warnings unduly pressured Coley to retract the testimony he initially gave at trial, and to adopt his testimony from the preliminary hearing. The court’s questioning clearly conveyed the impression that the trial court did not believe Coley’s trial testimony, and that Coley should adopt his testimony from the preliminary hearing. The court asked Coley five times if he was telling the truth at trial. The court repeatedly [327]*327asked Coley if any threats or promises caused him to testify falsely at trial, and asked Coley three times if he wanted to change or correct his testimony at trial. The court did not ask Coley if any threats or promises caused him to testify falsely at the preliminary hearing, or give Coley the opportunity to explain why he testified as he did at the preliminary hearing. The witness could have little doubt as to which testimony the court believed. The court’s questioning, coupled with the use of perjury warnings, improperly pressured the witness to change his trial testimony to conform with his testimony at the preliminary hearing.
The Commonwealth argues that the court’s action was harmless beyond a reasonable doubt. We cannot agree. Initially, Coley gave testimony favorable to appellant, indicating that someone other than appellant committed the killing. After extensive questioning by the court and admonishment on the consequences of perjury Coley retracted his earlier testimony and testified that he saw appellant stab the victim.
The Commonwealth relies on the testimony of two other witnesses. The first witness, Phillip Yant, testified that he saw appellant approach the victim. Although he did not see the stabbing, he did see the victim fall shortly thereafter. The second witness, Kevin White, testified that he saw appellant swing at the victim with a shiny object, after which the victim fell. White further testified that appellant later stated that he thought he stabbed the victim. According to White, appellant showed him the knife, and there was blood on the knife and on appellant’s hands.
We cannot find that the court’s action was harmless unless it was harmless beyond a reasonable doubt. See Commonwealth v. Davis, 455 Pa. 466, 317 A.2d 218 (1974); Salzburg, The Harm of Harmless Error, 59 Va.L.Rev. 988 (1973). The conclusion that the error was harmless beyond a reasonable doubt must be based on the court’s determination, beyond a reasonable doubt, that the error did not affect the jury verdict. Chapman v. California, 386 U.S. 18, 87 S.Ct. 824, 17 L.Ed.2d 705 (1967); see Commonwealth v. [328]*328Lippert, 454 Pa. 381, 384, 311 A.2d 586, 588 (1973). The determination that the error did not affect the jury verdict may be reached “as a result of a finding that the impact of the challenged evidence is de minimis, or [that] the evidence supports a fact already established and ... no longer in dispute.” Commonwealth v. Rodgers, 472 Pa. 435, 460, 372 A.2d 771, 783 (1977) (concurring and dissenting opinion of Nix, J.); accord, Commonwealth v. Hale, 467 Pa. 293, 298, 356 A.2d 756, 758 (1976) (error cannot be harmless beyond a reasonable doubt if challenged evidence “was neither cumulative nor insignificant”).
Clearly, the impact of Coley’s change in testimony, viewed by itself, cannot be viewed as de minimis. The Commonwealth in effect argues Coley’s testimony is merely cumulative of that given by the two other witnesses.11
The circumstances are extremely limited in which this Court may find that damaging testimony — such as Coley’s [329]*329testimony identifying appellant as the person who stabbed the victim — is harmless in light of other similar evidence. See generally Field, Assessing the Harmlessness of Federal Constitutional Error — A Process in Need of a Rationale, 125 U.Pa.L.Rev. 15 (1976). Professor Field has suggested that three requirements must be met before a court may conclude that improperly admitted evidence was merely cumulative of other evidence presented and therefore did not affect the jury verdict:
“(1) There should be substantial similarity, in type of evidence and incriminating factual details, between the tainted evidence and the untainted evidence of which it is ‘cumulative.’ (2) The untainted evidence should be indisputable, either because the facts are in some way affirmatively accepted by the defendant or for other reasons. (3) Care should be taken that the ‘untainted’ evidence in no way derives from the tainted evidence.”
Id. at 46.
We need not decide whether the testimony of Yant and White satisfies the first and third parts of this test, as it is clear that their testimony does not satisfy the second requirement: that their testimony be indisputable. The testimony of both witnesses was challenged on cross-examination, both as to ability to see the incident12 and as to credibility.13 Moreover, their testimony was contradicted by appellant and by appellant’s parents.14 In short, Coley’s [330]*330testimony did not merely “support a fact already established and ... no longer in dispute.” Commonwealth v. Rodgers, 472 Pa. 435, 460, 372 A.2d 771, 783 (1977) (concurring and dissenting opinion of Nix, J.).
Moreover, the damage to appellant from Coley’s change in testimony arises not only from Coley’s adoption of his preliminary hearing testimony identifying appellant as the killer, but from his retraction of his earlier testimony at trial. Indeed, Coley’s testimony that the person who approached the victim immediately before the victim fell from the stab wound was not in the courtroom, if believed, would have strongly supported acquittal. The Commonwealth has not met its burden of proving that the trial court’s error did not affect the jury verdict.15
