>>First, I do not understand how Galatians 1 can be used to disprove the Catholic Church.<<

The assumption of Mary is dogma in the Catholic faith. One must express belief in the assumption to be a member of the Catholic Church. The Catholic Church has also stated that there is no salvation outside the Catholic Church. Thus the belief in the assumption of Mary is needed for salvation per the Catholic Church. THAT is "another gospel" not taught by the apostles.

Yes it is a dogma, one runs the risk of heresy by being Catholic and not believing it; however, one is still a member of the Church.

Concerning "no salvation outside the Church", an explanation for why this is true but someone who is not Catholic can still go to heaven, is that in heaven they will be Catholic even if not here on Earth.

Thus the belief in the assumption of Mary is needed for salvation per the Catholic Church.

The only sin I am aware of that if committed could guarantee eternal damnation is that of blaspheming the Holy Spirit. We do have purgatory and prayers for the dead to handle other things.

I still do not see how the Assumption of Mary is another Gospel. And for that matter, I have seen no proof that the Apostles did not preach the Assumption of Mary or that Mary was not assumed.
