They are zealous of you, but not for good; yea, they would exclude you, that you might be zealous of them.
All Commentaries on Galatians 4:17 Go To Galatians 4
John Chrysostom
AD 407
It is a wholesome emulation which leads to an imitation of virtue, but an evil one, which seduces from virtue him who is in the right path. And this is the object of those persons, who would deprive you of perfect knowledge, and impart to you that which is mutilated and spurious, and this for no other purpose than that they may occupy the rank of teachers, and degrade you, who now stand higher than themselves, to the position of disciples. For this is the meaning of the words that you may seek them. But I, says he, desire the reverse, that you may become a model for them, and a pattern of a higher perfection: a thing which actually happened when I was present with you.
