I don’t agree. The Bible is clear on Jesus having siblings. They used different words to describe other relationships etc. It’s very clear. The reason it matters is because many people are praying to Mary in hopes she will intercede for them. That is dead smoking wrong and directly against biblical teachings. To say that won’t affect salvation is wrong because Jesus tells us how to be saved.
I think you overcomplicate the matter. As I read the Bible, there are three components to salvation: believe in Jesus, repent, be born again. Admittedly Catholics pray to Mary (and various other saints) and I think they are wrong to do so. All of us, Protestant and Catholic, do many things which, taken alone, might cast our salvation into doubt according to someone. But do those things invalidate our salvation if we’ve met the three criterion? No, because the blood of Jesus covers those sins and errors. So, praying or not praying to Mary won’t invalidate your salvation; believing or not believing the bread becomes the literal body of Christ won’t invalidate your salvation; drinking grape juice instead of wine at communion won’t invalidate your salvation. Do you get my point? These matters are principles worked out by the various religious groups for reasons that seem right to them, but they are NOT the basis for your salvation.
