No instead we speak the Gospel and let The Holy Spirit do the rest. Constantly putting someone on the defensive will accomplish nothing. Putting fellow Christians on the defensive over theology over and over again solves nothing either. Mankind is given Freewill. I don't worry much about someone in a church yes even Roman Catholic who personally acknowledges Christ as Lord and Savior. I'm far more concerned about a person who has never done so. Most persons are in the Roman Catholic Church because GOD led them there the same with other churches.
I know who Christ brothers and mother is and are as well as He himself stated. Look let me put it this way. If Catholic were praying to the moon goddess whatever for intercession I would see it as blasphemy as I would any church. Some verses in the Bible hint at intercession prayer in a few passages. One is a man in hell asking Abraham to has his servant bring him something to drink. Of course Abraham says so.
The Roman Catholics I know personally most of which is family acknowledge Christ as their Lord and Savior.
No, they pray to Mary. That’s as bad as a moon goddess. I know many born again Catholics as well. They’re good people. But there are many who don’t really have a clue.
