“How can the Catholic Church be the Church of Christ when historically they do not follow the teachings of Christ”.
You only know the teachings of Christ because CATHOLICS decided to tell you about them when they compiled the Bible.
The fullness of the faith is sacred scripture and sacred
tradition, something protestants can seem to grasp.
“But there are also many other things which Jesus did; were every one of them to be written, I suppose that the world itself could not contain the books that would be written”.
~ John 21:20-25
