Woe unto you, scribes and Pharisees, hypocrites! for you travel on sea and land to make one proselyte, and when he is made, you make him twofold more the child of hell than yourselves.
All Commentaries on Matthew 23:15 Go To Matthew 23
George Leo Haydock
AD 1849
Because whilst a Gentile he sinned without a perfect knowledge of the evil, and was not then a two-fold child of hell; but after his conversion, seeing the vices of his masters, and perceiving that they acted in direct opposition to the doctrines they taught, he returns to the vomit, and renders himself a prevaricator, by adoring the idols he formerly left, and sells his soul doubly to the devil. (St. Chrysostom)
They that teach that it is sufficient to have faith only, do make such Christians as blindly follow them, as these Jews did their proselytes, children of hell far more than before. (St. Augustine, lib. de fide et oper. chap. xxvi.)
