John 20:21

As the Father hath sent me. The word mission, when applied to our Saviour Christ, sometimes signifies his eternal procession from the Father, and sometimes his mission, as he was sent into the world to become man, and the Redeemer of mankind: the first mission agrees with him, as the eternal Son of God; the second, as man, or as both God and man. The mission which Christ here gives his apostles, is like this latter mission, with this great difference, that graces and divine gifts were bestowed on Christ, even as man, without measure: and the apostles had a much lesser share in both these missions. See St. Augustine, lib. iv. de Trin. chap. xix. xx. tom. 4. p. 829. and seq. (Witham) — Jesus Christ here shews his commission, and so giveth power to his apostles to forgive sins, as when he gave them commission to preach and baptize throughout the world, he made mention of his own power. Hence, whosoever denies the apostles, and their successors, the right of preaching, baptizing, and remitting sins, must consequently deny that Christ, as man, had the power to do the same. St. Cyprian, in the 3rd century, ep. lxxiii. says: “for the Lord, in the first place, gave to St. Peter, on whom he built his Church, super quem ædificavit Ecclesiam, the power that what he loosed on earth, should be loosed also in heaven. And after his resurrection, he speaks also to his apostles, saying, as the Father sent me, &c. whose sins you shall forgive,” &c. Why, on this occasion, passing over the other apostles, does Jesus Christ address Peter alone? Because he was the mouth, and chief of the apostles. (St. Chrysostom, de Sacerd. lib. ii. chap. 1.)

(3.) The honourable and ample commission he gave them to be his agents in the planting of his church, v. 21. Here is,

Verses 19-25 This was the first day of the week, and this day is afterwards often mentioned by the sacred writers; for it was evidently set apart as the Christian sabbath, in remembrance of Christ's resurrection. The disciples had shut the doors for fear of the Jews; and when they had no such expectation, Jesus himself came and stood in the midst of them, having miraculously, though silently, opened the doors. It is a comfort to Christ's disciples, when their assemblies can only be held in private, that no doors can shut out Christ's presence. When He manifests his love to believers by the comforts of his Spirit, he assures them that because he lives, they shall live also. A sight of Christ will gladden the heart of a disciple at any time; and the more we see of Jesus, the more we shall rejoice. He said, Receive ye the Holy Ghost, thus showing that their spiritual life, as well as all their ability for their work, would be derived from him, and depended upon him. Every word of Christ which is received in the heart by faith, comes accompanied by this Divine breathing; and without this there is neither light nor life. Nothing is seen, known, discerned, or felt of God, but through this. After this, Christ directed the apostles to declare the only method by which sin would be forgiven. This power did not exist at all in the apostles as a power to give judgment, but only as a power to declare the character of those whom God would accept or reject in the day of judgment. They have clearly laid down the marks whereby a child of God may be discerned and be distinguished from a false professor; and according to what they have declared shall every case be decided in the day of judgment. When we assemble in Christ's name, especially on his holy day, he will meet with us, and speak…
