Reformed Baptists Irritate Me

I am having another e-mail discussion with a Reformed Baptist about several things, particularly about the ordo salutis, and whether faith precedes or follows regeneration (rebirth). I had another long debate recently with a Hardshell Baptist (who believes like the Reformed folks) on this question and he did not want it published although I thought many would enjoy reading it. He also chose not to continue the debate. 

The present debate with the Reformed Baptist brought the brother to say that I John 5: 1 in the Greek taught that the birth preceded and was completed before faith. Of course, I have shown, as have others, that the text teaches no such thing! But, is it not insulting of these Reformers to indict the great Calvinists and Reformers of the past? Men who were experts in Greek (as Luther, Calvin, etc.) did not conclude that I John 5: 1 taught that the birth preceded faith! They therefore insult those men when they say "the Greek of that text proves that regeneration precedes faith." Such arrogant presumption! Luther and Calvin did not know Greek? Balderdash!
