The Catholic Church’s doctrine is closer to Judaism than Christianity.
1. Salvation by works alone
2. God’s presence in ONE location (Eucharist vs Holy of Holies)
3. No salvation outside of the Church (no protestants vs. no gentiles)
4. The view that “God’s house” must be grandiose and expensive (like Solomon’s temple)
5. One individual to communicate with God (Pope vs. High Priest)
6. Neither believe that the sacrifice of Christ paid for our sins forever.
Aside from those similarities I could also point to the selling of indulgences during the Protestant Reformation. Your money in exchange for forgiveness. That’s the same thing the money changers were doing in the synagogues when Jesus overturned their tables and drove them out with a whip.
You’re right, of course. If it ain’t in the Bible (and I read the King James version) it ain’t of God. You can have your version and your extra books and all that hoodoo. help yourself!
You mean as opposed to the Platonism and rationalism that characterizes much of Protestantism? I'll take it. Judaism is a religion founded by God, not by men. Catholicism is a religion founded by God, not by men. Two books in a series, by the same Divine Author, ought to have some similarities.
Every item on your list is provably false, BTW, but I want to zero in on one:
1. Salvation by works alone
Whoever told you this was Catholic belief lied to you, mischaracterizing as Catholic belief the heresy of Pelagianism, which the Catholic Church has repeatedly condemned. I have no hesitation about saying that they lied to you. Worse, they lied to you in God's name. That's a lot worse than "selling" indulgences, if you ask me.
This is de fide Catholic doctrine. Catholics are required to believe it under pain of heresy. Tell me where you get "salvation by works alone" out of it.
Salvation is purely by grace from beginning to end, and cannot be earned by anyone. It is sonship by adoption.
However, it matters how we live our lives. Grace is not always irresistable (pace Calvin). Salvation is a free gift; damnation can be earned. (cf Romans 6:23)
