My son once dated a girl who was a Southern Baptist. He went once to a Sunday service at her church and walked out when the preacher said Catholics were going to hell because of their veneration of the Virgin Mary.
Is Ryan now a target because he is a Catholic?
Probably. And the Baptists are wrong, too, about that and many other things.
What I see as the major issue with Christians, Christianity, and those religions which claim to be so is their bringing extraneous rules, doctrines, and people’s opinions (some call them ‘prophetic visions’) into their belief system instead of relying solely upon the Holy Scriptures and studying what God and the Holy Spirit have to say.
There seem to be theological errors in this church’s take, but as your son probably doesn’t grok Christian theology anyhow, it would be meaningless to say he sees errors in this particular Baptist church’s version of theology.
Evangelicals teach that hailing Mary is wrong, that it is something God never wanted, but this is not classified as an unforgivable sin.
