If calvinism was fully true then the Holy Spirit would not have had it called Calvinism. It would have simply been called “The Way” or simply Christianity. The doctrines of Calvin have been teased from the pages of the Bible, almost set apart from The Word Logos made flesh.
If Calvinism was the way we were to interpret the bible plan of Salvation...then it would not have been allowed to be called “Calvinism”...it would have been called ‘The true way of Christ”.
Calvin’s theology wasn’t unique to him alone.
You have to excise large portions of Paul’s teachings to refute Calvin.
