For you were going astray like sheep; but are now returned to the Shepherd and Overseer{"Overseer" is from the Greek episkopon, which can mean overseer, curator, guardian, or superintendent.} of your souls.
And this appears still more evident from the clause which follows, but are now returned to the Shepherd, etc.; (35) for all who are not ruled by Christ, are wandering like lost sheep in the ways of error. Thus, then, is condemned the whole wisdom of the world, which does not submit to the government of Christ. But the two titles given here to Christ are remarkable, that he is the Shepherd and Bishop of souls There is then no cause to fear, but that he will faithfully watch over the safety of those who are in his fold and under his care. And it is his office to keep us safe both in body and soul; yet Peter mentions only souls, because this celestial Shepherd keeps us under his own spiritual protection unto eternal life.
