I said:>>If the Pope says we need to believe it then it is so.<<
You said: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. As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed. Galatians 1:8-9
I now say:
Well, preaching a gospel that denies the power of binding and loosing that was given to Peter and his office (the papacy) seems to lead to lead to damnation, according to a narrow reading of your chosen Galatians verse.
The assumption of Mary is not contrary to the Gospel. I read the Galations verse to refer to any teaching opposed to previously declared doctrine.
>>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.<<
If the Apostles didnt teach it nuff said.
