Catholicism believes in God and that Jesus is the Son of God and that Jesus died on the cross for the salvation of the world. I didn't know that Protestantism rejected those ideas. In other words, your statement is idiotic, possibly the most idiotic statement I've ever heard on FR, and I've heard a few.
If Catholicism ACTUALLY believed what you just stated, and left it right there, they'd have it. But, the Catholic cult ADDS uncessary
Catholicism teaches:
that Mary is a mediatrix, which is unbiblical;
that she was taken bodily into Heaven -- unbiblical;
that she was born sinless -- unbiblical;
that Mohammedans worship the same God as Catholics -- unbiblical -- and in that particular case, makes Catholicism SATANIC in my book.
that salvation, as you stated is NOT by Christ alone, but by faith AND works -- unbiblical.
that there is a place called Purgatory -- doesn't exist and is unbiblical;
that Mary and other saints are to be prayed to -- which is idolatry -- and against biblical teaching.
So, to you, my statement my sound idiotic... and it may since you have been so thoroughly brainwashed by the Roman Catholic cult. But, if you would READ THE BIBLE, you will find that so much of what Rome has taught, and currently teaches, goes directly against what God teaches.
And, you might find the truth.
