"Rule 610 proscribes the admissibility of evidence of the religious beliefs or opinions of a witness for the purpose of attacking his credibility. Such evidence may be admitted to show interest or bias of the witness. This is a rule of evidence and does not affect jury arguments, except in support of the rule that counsel ordinarily may not argue matters not supported by the evidence. State v. James, 322 N.C. 320, 323-24, 367 S.E.2d 669, 671 (1988).
