Acts 20:28

Take heed . . . unto yourselves--Compare Ti1 3:2-7; Ti1 4:16; Ti1 6:11. and to all the flock--Compare Heb 13:17. Observe here how the personal is put before the pastoral care. over . . . which the Holy Ghost hath made you--Compare Joh 20:22-23; Eph 4:8, Eph 4:11-12; Rev 3:1. (Act 14:23 shows that the apostle did not mean to exclude human ordination). overseers--or, as the same word is everywhere else rendered in our version, "bishops." The English Version has hardly dealt fair in this case with the sacred text, in rendering the word "overseers," whereas it ought here, as in all other places, to have been "bishops," in order that the fact of elders and bishops having been originally and apostolically synonymous, might be apparent to the ordinary English reader, which now it is not [ALFORD]. The distinction between these offices cannot be certainly traced till the second century, nor was it established till late in that century. to feed the church of God--or, "the Church of the Lord." Which of these two readings of the text is the true one, is a question which has divided the best critics. The evidence of manuscripts preponderates in favor of "THE LORD"; some of the most ancient Versions, though not all, so read; and ATHANASIUS, the great champion of the supreme Divinity of Christ early in the fourth century, says the expression "Church of God" is unknown to the Scriptures.
