Calvin may have articulated Scripture when he put forth the TULIP
Calvin
didn't "put forth" TULIP. He taught the Doctrines of Grace before the doctrines were doctrines. There were contemporaries of Calvin that did the same. The five Doctrines of Grace developed into the acrostic TULIP from the
The Decision of the Synod of Dordt on the Five Main Points of Doctrine in Dispute in the Netherlands (The Canons of Dordt) which were a direct correction of the five statements of doctrine of the Remonstrants (followers of Jacob Arminius).
Calvin's teachings, and the teachings of his contemporary Reformers, were much more prolific than the five Doctrines of Grace.
I am aware of all of this. My point was that the doctrines collectively known as TULIP did not originate with Calvin and in fact are found in Scripture. Luther, Augustine, and others have all articulated certain points within that acrostic. Where did they get it? From Scripture.
