No. Jesus doesn't make stuff up. The RCC however does.
I am glad you recognize we do not have everything Jesus ever said or did recorded. As John notes the whole world wouldn't be able to contain them.
I believe in Him and Him alone as the Bible tells us that is the only way to have eternal life.
I follow the Biblical instructions regarding honor to "whom honor is due".
I also follow the Biblical instruction to test every spirit.
1 John 4:1
Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.
I have tested the teachings of the RCC and find many that are false prophets that have gone out into the world.
