1 Peter 2:25

For ye were, while ye continued in your Judaism, and had not yet received the gospel, as sheep going astray, from Christ the great Shepherd, and the church of believers his flock, and the way of righteousness in which he leads them. Ye were alienated from the life of God, bewildered and lost in the way of sin, Isaiah 53:6.

But are now returned, in your conversion to the faith,

to the Shepherd; Christ the good Shepherd, John 10:11,John 10:14,John 10:16, that takes care of souls, as a shepherd doth of his sheep.

And Bishop of your souls; superintendent, inspector, or, as the Hebrews phrase it, visitor, i.e. he that with care looks to, inspects, and visits the flock. This he adds for the comfort (as of all believers, so) particularly of servants, that even they, as mean as they were, and as much exposed to injuries, yet were under the care and tuition of Christ.
