Jesus doesn't have a Catholic Church...
Your reliance on Scripture alone ignores that Jesus Christ appointed a leader of His church and that Scripture came from sacred tradition and the leaders of the Catholic Church.
Scripture alone PROVES that Jesus did NOT appoint a leader of his church and that scripture is the written tradition of what was taught to the apostles/disciples...
The author does not believe in the authority of the papacy and the magisterium, yet acknowledges Peter as the leader of the Church. Somehow he fails to acknowledge that the Scriptures came both from the Church leaders - the Popes and Bishops and from the magisterium.
And how do you know this??? From scripture??? NOPE...
You learned it from your popes, bishops and magisterium, which are foreign to the scriptures...
So the Amen chorus just ignores history and it interprets the Bible accordingly.
If you tell yourself often enough, you begin to believe it is the truth.
So Peter and the apostles and their successors are fiction.
Again, you should thank the Catholic Church for following sacred tradition and preserving the Bible so that you can read it and dispute the words of God that you do not agree with.
