Then said Jesus unto them again,
Verily, verily, I say unto you, I am the door of the sheep.
All Commentaries on John 10:7 Go To John 10
Theophilus of Antioch
AD 184
The door admits the sheep into the pasture; And shall go in and out, and find pasture. What is this pasture, but the happiness to come, the rest to which our Lord brings us? .
Or, to go in is to watch over the inner man; to go out, to mortify the outward man, i.e. our members which are upon the earth. He that does this shall find pasture in the life to come.
Mystically, the thief is the devil, steals by wicked thoughts, kills by the assent of the mind to them, and destroys by acts.
