No one has proved that the teachings of the Catholic Church are not the same as what Jesus taught the Apostles. I am not aware of any.

Ephesians 2:3–10
[3] among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. [4] But God, being rich in mercy, because of the great love with which he loved us, [5] even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—[6] and raised us up with him and seated us with him in the heavenly places in Christ Jesus, [7] so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. [8] For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, [9] not a result of works, so that no one may boast. [10] For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.”
Proof: SUPPLIED.
Before I mic drop, Would you like to see how the early church fathers blatantly contradict Roman Catholic teaching, especially in regards to the doctrine of salvation too?
I see that you can quote scripture, but you didn’t prove anything.
Please be specific on which teaching and explain how the Catholic Church erred.
On your other posting Luther was excommunicated. Specific quotes from early Christians is not always the teaching of the Catholic Church. Specific quotes may be taken out of context.
