Albert Barnes Commentary John 10:2

"But he that entereth in by the door is the shepherd of the sheep." — John 10:2 (ASV)

He that entereth by the door. This was the way in which a shepherd had access to his flock. In John 10:7 Jesus says he is the door. In this place he refers to those who by him—that is, in accordance with his spirit and law—become ministers of religion.

Is the shepherd of the sheep. Christ does not here refer to himself, for he is the way or door by which others enter; but he refers to all the ministers of the gospel who have access to the church by him. In the original, the article "the" is lacking before the word shepherd—“is a shepherd.” By his entering in this manner he shows that he is a shepherd—one who cares for his flock, and does not come to kill and destroy.
