Ephesians 4:30

A matter this more terrible and startling, as he also says in the Epistle to the Thessalonians; for there too he uses an expression of this sort. "He that rejecteth, rejecteth not man, but God." (1 Thess. iv. 8.) So also here. If thou utter a reproachful word, if thou strike thy brother, thou art not striking him, thou art "grieving the Holy Spirit." And then is added further the benefit bestowed, in order to heighten the rebuke. "And grieve not the Holy Spirit," saith He, "in whom ye were sealed unto the day of redemption." He it is who marks us as a royal flock; He, who separates us from all former things; He, who suffers us not to lie amongst them that are exposed to the wrath of God,-and dost thou grieve Him? Look how startling are his words there; "For he that rejecteth," saith he, "rejecteth not man, but God:" and how cutting they are here, "Grieve not the Holy Spirit," saith he, "in whom ye were sealed." Let this seal then abide upon thy mouth, and never destroy the impression. A spiritual mouth never utters a thing of the kind. Say not, "It is nothing, if I do utter an unseemly word, if I do insult such an one." For this very reason is it a great evil, because it seems to be nothing. For things which seem to be nothing are thus easily thought lightly of; and those which are thought lightly of go on increasing; and those which go on increasing become incurable. Thou hast a spiritual mouth. Think what words thou didst utter immediately upon being born, -what words are worthy of thy mouth. Thou callest God, "Father," and dost thou straightway revile thy brother? Think, whence is it thou callest God, "Father"? Is it from nature? No, thou couldest never say so. Is it from thy goodness? No, nor is it thus. But whence then is it? It is from pure lovingkindness, from tenderness, from His great mercy. Whenever then thou callest God, "Father," consider not only this, that by reviling thou art committing things unworthy of that, thy high birth, but also that it is of lovingkindness that thou hast that high birth. Disgrace it not then, after receiving it from pure lovingkindness, by showing cruelty towards thy brethren. Dost thou call God "Father," and yet revile? No, these are not the works of the Son of God. These are very far from Him. The work of the Son of God was to forgive His enemies, to pray for them that crucified Him, to shed His blood for them that hated Him. These are works worthy of the Son of God, to make His enemies,-the ungrateful, the dishonest, the reckless, the treacherous,-to make these brethren and heirs: not to treat them that are become brethren with ignominy like slaves. Think what words thy mouth uttered,-of what table these words are worthy. Think what thy mouth touches, what it tastes, of what manner of food it partakes! Dost thou deem thyself to be doing nothing grievous in railing at thy brother? How then dost thou call him brother? And yet if he be not a brother, how sayest thou, "Our Father"? For the word "Our" is indicative of many persons. Think with whom thou standest at the time of the mysteries! With the Cherubim, with the Seraphim! The Seraphim revile not: no, their mouth fulfills this one only duty, to sing the Hymn of praise, to glorify God. And how then shalt thou be able to say with them, "Holy, Holy, Holy," if thou use thy mouth for reviling? Tell me, I pray. Suppose there were a royal vessel, and that always full of royal dainties, and set apart for that purpose, and then that any one of the servants were to take and use it for holding dung. Would he ever venture again, after it had been filled with dung, to store it away with those other vessels, set apart for those other uses? Surely not. Now railing is like this, reviling is like this. "Our Father!" But what? is this all? Hear also the words, which follow, "which art in Heaven." The moment thou sayest, "Our Father, which art in Heaven," the word raises thee up, it gives wings to thy mind, it points out to thee that thou hast a Father
