John Wesley on John 10:8

Whosoever are come - Independently of me, assuming any part of my character, pretending, like your elders and rabbis, to a power over the consciences of men, attempting to make laws in the Church, and to teach their own traditions as the way of salvation: all those prophets and expounders of God's word, that enter not by the door of the sheepfold, but run before I have sent them by my Spirit. Our Lord seems in particular to speak of those that had undertaken this office since he began his ministry, are thieves - Stealing temporal profit to themselves, and robbers - Plundering and murdering the sheep.
