Joseph might have had previous children...not Mary
I don't think they became true Christians until after the death and resurrection of Christ, and we don't even know for sure, if all of them got saved, or if only some of them, but I think Jesus' half brother James, was the leader of the Jerusalem church. If people disagree, that's on them.
Yeah, Christ came to Earth to save mankind and then condemned some of His family members to Hell....Now that's really merciful.....sheesh.
Pure(?) speculation.
He certainly WILL, if they never became Christians. Remember, only Christians will go to Heaven. To reject Him, however, would be their choice. If you want to tell Jesus you don't like the way He is running the show, knock yourself out.
Why do you care about His brothers and sisters anyway? You are a Catholic. I think you believe they did not exist. I am an ex Catholic. I believe they did exist. I just don't know if they all got saved. They might have. We just don't know. It is not important to our salvation.
If anyone, including them and you, do not wish to get saved, that's on you. He provided the way. It's up to you to respond to it. Get over it. Sheesh.
