[CynicalBear]

Galatians 1:8 But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.

All Catholics need to do is show from an infallible source that the apostles taught the assumption of Mary. If they cannot then we must consider those who teach it accursed.

All Catholics need to do is show from an infallible source that the apostles taught the assumption of Mary.

When we do show you things like "So faith by itself, if it has not works, is dead." (Jas 2:17), you persist in believing in faith only salvation. Jesus extols the virtue of perpetual virginity and Paul wishes that others could be like him in that regard. But Protestants insist on believing it is not so. When shown things like Jesus renaming Simon to Peter, like God renaming Avram to Abraham or Jacob to Israel, you reject any specialness of Peter. So why should we believe that you will believe the Assumption if we find a passage that supports it.
