This summary is not the rule. The rule text controls.
Lawyers can't use a witness's religious beliefs to make them look more or less believable in court. What someone does or doesn't believe about religion has nothing to do with whether they're telling the truth on the stand.
For example, a lawyer can't argue that a witness is honest because they regularly attend church, or that they're dishonest because they don't follow a particular faith or don't believe in God at all. This kind of evidence simply is not allowed for this purpose.
This rule keeps trials focused on facts that actually matter, like what a witness saw, heard, or knows about the case. It also protects people's privacy when it comes to their personal religious views, keeping those beliefs separate from questions about their honesty as a witness.
