Textually in the Scriptures that makes no sense. Transpose your definition throughout the book of Romans. Change every reference to Israel and related names (Israelite, sheep of Israel, children of Israel, men of Israel, Jacob, Zion, etc.) to "Church." Continue with the rest of the NT books.
you had to have been taught the faith post VII.
one would think someone calling themself a “Catholic” would know there is national Israel, which is a “type” of the real Israel, which is the Church.
put away your 19th century John Darby beliefs and learn what the Church has taught for 2,000 years ( up until the VII disaster )
Thank you. I agree, it doesn’t make sense.
