João 4
Ambrose of Milan · Comentário Patrístico (catena)
João 4:6
Many things we read and believe, in the light of the sacrament of the incarnation. Even in the very affections of our human nature we behold the divine majesty. Jesus is wearied with his journey, that he may refresh the weary. He desires to drink when about to give spiritual drink to the thirsty; he was hungry, when about to supply the food of salvation to the hungry. — Exposition of the Christian Faith 5.4.53
João 4:11
This well is clearly the grace of the Spirit, a stream proceeding from the living fountain. The Holy Spirit, then, is also the fountain of eternal life.… This water, the grace of the Spirit, is so refreshing. Who will give this fountain to my breast? Let it spring up in me, let what gives eternal life flow on me. Let that fountain overflow on us and not flow away.… How shall I keep this water so that it does not flow or glide away? — On the Holy Spirit 1.16.180-81
João 4:23
In the mystical doctrine, we understand that this well is also referred to there, because there the Samaritan woman, that is, the guardian (the guardian, however, of heavenly precepts), drew divine mysteries from that well, knowing that God is spirit, and is not worshipped in a place but in spirit; and because he is the Messiah, Christ. And therefore, he who is still expected by the Jews has already come. Having heard these things, that woman who appears to be of the Church, recognized the sacraments of the law, and believed. — On Isaac and the Soul 4.26
João 4:23
What does it mean, then, that the Father is worshiped in Christ, except that the Father is in Christ and the Father speaks in Christ and abides in Christ? He does not abide, indeed, as a body in a body, for God is not a body.… So not an engrafting of a body is meant, but unity of power. Therefore, by unity of power, Christ is jointly worshiped in the Father when God the Father is worshiped in Christ. In the same way then, by unity of the same power the Spirit is jointly worshiped in God when God is worshiped in the Spirit.… When God is said to be worshiped in truth (by the proper meaning of the word itself often expressed after the same manner), it ought to be understood that the Son too is worshiped. So, in the same way, the Spirit is also worshiped because God is worshiped in Spirit. Therefore the Father is worshiped both with the Son and with the Spirit, because the Trinity is worshiped. — On the Holy Spirit 3.11.82, 85
João 4:34
The food of a priest is the remission of sins. Therefore, the Prince of priests, Christ, says, "My food is to do the will of him who sent me." What is the will of God but this: "When you turn and groan, then shall you be saved"? — LETTER 57 (TO SIMPLICIANUS)
João 4:34
But as Christ is not yet made subject [to the Father], so also is the work of God not yet perfected. For the Son of God said, "My food is to do the will of him who sent me and to complete his work." How can anyone doubt that the subjection of the Son in me is still in the future when the work of the Father is still unfinished [in me] because I myself am not yet perfect? — Exposition of the Christian Faith 5.13.169
