That is impossible.
Actually since several of God’s covenants with His Jewish people are unconditional, yes the Church fathers who taught otherwise were mistaken. ( it’s either that or God is a liar. I refuse to accept or pray to a lying god. Therefore, the last 4 popes or so are correct on this point, imho. ). Respectfully, fhc. Ps: I respect the fact that some people reject all of Vatican 2 or most of it. Nevertheless, Nostra aetate won the support of 2221 bishops , to only 88 against, and thus clearly represents a teaching worth considering and prayer, imho, especially insofar as there is clear Holy Scriptural basis for at least it’s discussion of God’s “chosen” people. All popes then and since have gone out of their way to reinforce this one aspect of the teaching, too That’s about the best I can do — blessings, Genesis 12:3
