Please do a study on replacement theology....for that is what you believe in. Revelation makes it clear as well as all scripture, that God is not done with Israel. When God makes a covenant/promise, He doesn’t break it. He made many with Israel specifically. We are grafted in. They are not pruned out or replaced. I most humbly urge you to review this.
I’ve done a study of the book of Revelation and I have several books on what the early Church has to say about it. Did you know that the Holy Catholic Mass is described in that book?
