Heresy does not begin in the head with doctrines, it begins in the heart with the love of sin. It begins in the heart and it moves to the head. Every heretic in the history of the world has loved his/her sin and loved unrighteousness, and would not repent. And so they twisted the true and precious doctrines of Christianity. I think what Jude is saying is that these men, who had crept in, did that—they twisted the grace of God so that they would not have to repent from their sin, and so they denied Jesus Christ and became intellectual heretics.1

4 Car il s'est glissé parmi vous certains hommes dont la condamnation est écrite depuis longtemps, des impies, qui changent la grâce de notre Dieu en dérèglement, et qui renient notre seul maître et Seigneur Jésus-Christ.
