So you are a Jew who has abandoned the Hebraic foundation of Christianity by accepting traditions developed by gentiles. That is unfortunate since what you teach as truth has a lot of the spirit of Babylon as its foundation.
Numbers 23:19
9 "God is not a man, that He should lie,
Nor a son of man, that He should repent;
Has He said, and will He not do it?
Or has He spoken, and will He not make it good?
NAS
A millstone awaits those who offend the children of God? Where do you get this from? Christians offend Christians on a daily basis. As to my stance on Catholicism, what does that have to do with Judaism and this thread? If you know anything about pre Vatican II Catholicism you would know that the official stance of the Catholic Church was that all non-Catholics were doomed to an eternity in the lake of fire since the Catholic Church taught that salvation came only through the Catholic Church. You should read up on the Council of Trent.
However, how does your OP advance the Gospel?
