Acts 20:28

"Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers (or, bishops) to feed the Church of God, which He hath purchased with His own blood." Do you mark? he enjoins them two things. Neither success in bringing others right of itself is any gain-for, I fear, he says, "lest by any means, when I have preached to others, I myself should be a cast-away" (1 Cor. ix. 27); nor the being diligent for one's self alone. For such an one is selfish, and seeks his own good only, and is like to him who buried his talent. "Take heed to yourselves:" this he says, not because our own salvation is more precious than that of the flock, but because, when we take heed to ourselves, then the flock also is a gainer.

"In which the Holy Ghost hath made you overseers, to feed the Church of God." See, it is from the Spirit ye have your ordination. This is one constraint: then he says, "To feed the Church of the Lord." Lo! another obligation: the Church is the Lord's. And a third: "which He hath purchased with His own blood." It shows how precious the concern is; that the peril is about no small matters, seeing that even His own blood He spared not. He indeed, that he might reconcile those who were enemies, poured out even His blood: but thou, even when they are become thy friends, art not able to retain them.

"What then," someone might say, "thinkest thou thyself so great? if thou shouldest depart, are we to die?" I say not this, he replies, that my absence causeth this: but what? That there should rise up against you certain of another sort: he says not, "because of my departing," but "after my departing:" that is, after his going on his journey. And yet this thing has happened already: much more (then will it happen) hereafter. Then we have the cause, "to draw away disciples after them." That there are heresies, this is the cause, and no other than this. Then comes also consolation. But if He "purchased" it "with His own blood," He will assuredly stand forward in its defence.

In which the Holy Spirit has made you overseers. For above he had called the elders called from Ephesus to Miletus, whom he now names bishops, that is, overseers. For indeed one city could not have many bishops, but he signifies those same elders, as …

"Pay attention to yourselves and to all the flock," because salvific benefit consists not only in correcting others — I fear, says the apostle, "lest, having preached to others, I myself should be disqualified" (1 Cor. 9:27) — but also not only in caring for …

To rule the Church of God, which He purchased with His own blood. He does not doubt to call it the blood of God, on account of the union of the person in the two natures of the same Jesus Christ. Because of which it …

To do this is the peculiar work of the Holy Ghost: to feed the Church of God - That is, the believing, loving, holy children of God; which he hath purchased - How precious is it then in his sight! with his own blood - For it is the blood of the only begotten Son of God, 1 John i, 7.

Take heed therefore unto yourselves,....

And as the sacrificial atoning character of Christ's death is here plainly expressed, so His supreme dignity is implied as clearly by the second reading as it is expressed by the first.

Take heed, therefore - Attend to; be on your guard against the dangers which beset you, and seek to discharge your duty with fidelity. Unto yourselves - To your own piety, opinions, and mode of life. This is the first duty of a minister; for without this all his preaching will be vain. Compare Col 4:17; 1Ti 4:14. Ministers are beset with unique dangers and temptations, and against them they should be on their guard. In addition to the temptations which they have in common with other people, they are exposed to those special to their office - arising from flattery, and ambition, and despondency, and worldly-mindedness. And just in proportion to the importance of their office is the importance of the injunction of Paul, to take heed to themselves. And to all the flock - The church; the charge entrusted to them. The church of Christ is often compared to a flock. See the John 10:1-20 notes; also Joh 21:15-17 notes. The word “flock” here refers particularly to the church, and not to the congregation in general, for it is represented to be what was purchased with the blood of the atonement. The command here is: (1) To take heed to the church; that is, to instruct, teach, and guide it; to guard it from enemies Act 20:29, and to make it their special object to promote its welfare. (2) To take heed to all the flock the rich and the poor, the bond and the free, the old and the young. It is the duty of ministers to seek to promote the welfare of each individual of their charge not to pass by the poor because they are poor, and not to be afraid of the rich because they are rich. A shepherd regards the I interest of the tenderest of the fold as much as the strongest; and a faithful minister will seek to advance the interest of all. […]
