Psalms 76:21

20. “Thou hast led home Thy people like sheep in the hand of Moses and of Aaron” ( ver. 20 ). Why He hath added this is somewhat difficult to discover.…They banished Christ; sick as they were, they would not have Him for their Saviour; but He began to be among the Gentiles, and among all nations, among many peoples. Nevertheless, a remnant of that people hath been saved. The ungrateful multitude hath remained without, even the halting breadth of Jacob’s thigh. For the breadth of the thigh is understood of the multitude of lineage, and among the greater part of the Israelites a certain multitude became vain and foolish, so as not to know the steps of Christ on the waters. “Thou hast led home Thy people like sheep,” and they have not known Thee. …

Let us now see further what he adds to this “sanctifying the saints.” If any one says this also of the Father and of the Son, he will speak truly. For those in whom the Holy One dwells, He makes holy, even as the Good One makes men good. And the Father, the Son, and the Holy Ghost are holy and good, as has been shown. “Acting as a guide to those who approach the mystery.” This may well be said of Apollos who watered what Paul planted. For the Apostle plants by his guidance, and Apollos, when he baptizes, waters by Sacramental regeneration, bringing to the mystery those who were instructed by Paul. Thus he places on a level with Apollos that Spirit Who perfects men through baptism. “Distributing every gift.” With this we too agree; for everything that is good is a portion of the gifts of the Holy Spirit. …

5. But since God, Who maketh poor and maketh rich, Who killeth and maketh alive; Who maketh and transformeth all things; Who turneth night into day, winter into spring, storm into calm, drought into abundance of rain; and often for the sake of the prayers of one righteous man sorely persecuted; Who lifteth up the meek on high, and bringeth the ungodly down to the ground; since God said to Himself, I have surely seen the affliction of Israel; and they shall no longer be further vexed with clay and brick-making; and when He spake He visited, and in His visitation He saved, and led forth His people with a mighty hand and outstretched arm, by the hand of Moses and Aaron, His chosen, what is the result, and what wonders have been wrought? Those which books and monuments contain. …

It is the Spirit which says, as the Lord says, “Get thee down, and go with them, doubting nothing: for I have sent them.” Are these the words of an inferior, or of one in dread? “Separate me Barnabas and Saul for the work whereunto I have called them.” Does a slave speak thus? And Isaiah, “The Lord God and His Spirit hath sent me,” and “the Spirit came down from the Lord and guided them.” And pray do not again understand by this guidance some humble service, for the Word witnesses that it was the work of God; “Thou leddest thy people,” it is said “like a flock,” and “Thou that leadest Joseph like a flock,” and “He led them on safely, so that they feared not.” Thus when you hear that when the Comforter is come, He will put you in remembrance, and “guide you into all truth,” do not misrepresent the meaning.
