These are the kinds of things that are discussed in sermons at both Catholic and Protestant churches.

Not in any church I've ever been in.

I can't ever recall hearing a sermon about circumcision.

Perhaps not specifically about circumcision but sermons about Christ and his relationship with the law of Moses are not uncommon at all. And they often use inference and analysis, which the original comment I was responding to suggests are just stumbling blocks.
