Annotation Law reviews. For article, "Impeachment", see 22 Colo. Law. 1207 (1993). For article, "Witness Competence and Credibility: The Relevance of Religious Beliefs", see 26 Colo. Law. 121 (June 1997). When evidence of beliefs admissible. Where evidence of witnesses' religious beliefs is relevant to the determination of questions other than impeaching or enhancing credibility, including the plaintiffs' standing to sue, the personal knowledge of certain witnesses as to religious practices about which they testified, and the basis for witnesses' opinions that the effect of a nativity scene was to prefer the Christian religion, questioning the witnesses about their religious beliefs is not objectionable under this rule. Conrad v. City & County of Denver, 656 P.2d 662 (Colo. 1982). This section was not violated in felony child abuse case where defendant raised religious healing as an affirmative defense and was cross-examined as to his religious beliefs. The examination was probative of something other than the veracity of such witness and the court properly instructed the jury to consider the defendant's testimony only for such limited purpose. People v. Lybarger, 790 P.2d 855 (Colo. App. 1989), rev'd on other grounds, 807 P.2d 570 (Colo. 1991). This rule and § 13-90-110 do not apply to statements made by a prosecutor in closing argument. A prosecutor is not a witness, and his or her statements made in closing argument are not evidence. People v. Krutsinger, 121 P.3d 318 (Colo. App. 2005). Applied in People v. Mandez, 997 P.2d 1254 (Colo. App. 1999).
