1 My lord and brother Severus still defers the pleasure we shall feel in his discourse, which he owes us; for he acknowledges, that he is held a debtor. For all the Churches through which he has passed, by his tongue the lord has gladdened: much more therefore ought that Church to be rejoiced, out of which the Lord has propagated his preaching among the rest. But what shall we do, but obey his will? I said, however, brethren, that he deferred, not that he defrauded us. Therefore let us keep him as a debtor bound, and release him not until he has paid. Attend therefore, beloved: as far as the Lord allows, let us say somewhat of this Psalm, which indeed you already know; for the fresh mention of truth is sweet. Possibly when its title was pronounced, some heard it with wonder. For the Psalm is inscribed: “When the house was being built after the Captivity.” This title having been prefixed, you were perhaps expecting in the text of the Psalm to hear what stones were hewn from the mountains, what masses were drawn to the spot, what foundations were laid, what beams were placed on high, what columns raised. Its song is of nothing of this kind....It is no such house that is in building; for behold where it is built, not in one spot, not in any particular region. For thus he begins:—
2. “O sing unto the Lord a new song; sing unto the Lord, all the earth”. If all the earth sings a new song, it is thus building while it sings: the very act of singing is building: but only, if it sings not the old song. The lust of the flesh sings the old song: the love of God sings the new....Hear why it is a new song: the Lord says, “A new commandment I give unto you, that you love one another.” The whole earth then sings a new song: there the house of God is built. All the earth is the house of God. If all the earth is the house of God, he who clings not to all the earth, is a ruin, not a house; that old ruin whose shadow that ancient temple represented. For there what was old was destroyed, that what was new might be built up....The Apostle binds us together into this very structure, and fastens us when bound together in that unity, saying, “Forbearing one another in love; endeavouring to keep the unity of the Spirit in the bond of peace.” Where there is this unity of Spirit, there is one stone; but one stone formed out of many. How one formed out of many? By forbearing one another in love. Therefore the house of the Lord our God is in building; it is this that is being wrought, for this are these words, for this these readings, for this the preaching of the Gospel over the whole world; as yet it is in building. This house has increased greatly, and filled many nations: nevertheless, it has not yet prevailed through all nations: by its increase it has held many, and will prevail over all: and it is gainsaid by those who boast of their being of its household, and who say, it has already lost ground. It still increases, still all those nations which have not yet believed are destined to believe; that no man may say, will that tongue believe? will the barbarians believe? What is the meaning of the Holy Spirit having appeared in the fiery tongues, except that there is no tongue so hard that it cannot be softened by that fire? For we know that many barbarous nations have already believed in Christ: Christ already possesses regions where the Roman empire has never yet reached; what is as yet closed to those who fight with the sword, is not closed to Him who fights with wood. For “the Lord has reigned from the wood.” Who is it who fights with wood? Christ. With His cross He has vanquished kings, and fixed upon their forehead, when vanquished, that very cross; and they glory in it, for in it is their salvation. This is the work which is being wrought, thus the house increases, thus it is building: and that you may know, hear the following verses of the Psalm: see them labouring upon, and constructing the house. “O sing unto the Lord all the earth.”
3. “Sing unto the Lord, bless His Name: be telling good tidings of His salvation from day to day”. How does the building increase? “Be telling,” he says, “good tidings of His salvation from day to day.” Let it be preached from day to day; from day to day, he says, let it be built; let My house, says God, increase. And as if it were said by the workmen, Where dost Thou command it to be built? Where do You will Your house to increase? Choose for us some level, spacious spot, if Thou wish an ample house built You. Where dost Thou bid us be telling good tidings from day to day? He shows the place: “Declare His honour unto the heathen:” His honour, not yours. O you builders, “Declare His honour unto the heathen.” Should ye choose to declare your own honour, you shall fall: if His, you shall be built up, while you are building. Therefore they who choose to declare their own honour, have refused to dwell in that house; and therefore they sing not a new song with all the earth. For they do not share it with the whole round world; and hence they are not building in the house, but have erected a whited wall. How sternly does God threaten the whited wall? There are innumerable testimonies of the Prophets, whence He curses the whited wall. What is the whited wall, save hypocrisy, that is, pretence? Without it is bright, within it is dirt....A certain person, speaking of this whited wall, said thus: “as, if in a wall which stands alone, and is not connected with any other walls, you make a door, whoever enters, is out of doors; so in that part which has refused to sing the new song together with the house, but has chosen to build a wall, and that a whited one, and not solid, what avails it that it has a door?” If you enter, you are found to be without. For because they themselves did not enter by the door, their door also does not admit them within. For the Lord says, “I am the door: by Me they enter in.”...“Declare His honour unto the heathen.” What is, unto the heathen? Perhaps by nations but a few are meant: and that part which has raised the whited wall has still somewhat to say: why are not Getulia, Numidia, Mauritania, Byzacium, nations? Provinces are nations. Let the word of God take the word from hypocrisy, from the whited wall, building up the house over the whole world. It is not enough to say, “Declare His honour unto the heathen;” that you may not think any nations excepted, he adds, “and His wonders unto all people.”
4. “For the Lord is great, and cannot worthily be praised”. What Lord, except Jesus Christ, “is great, and cannot worthily be praised”? You know surely that He appeared as a Man: ye know surely that He was conceived in a woman's womb, you know that He was born from the womb, that He was suckled, that He was carried in arms, circumcised, that a victim was offered for Him, that He grew; lastly, you know that He was buffeted, spit upon, crowned with thorns, was crucified, died, was pierced with a spear; ye know that He suffered all these things: “He is great, and cannot worthily be praised.” Despise not what is little, understand what is great. He became little, because you were such: let Him be acknowledged great, and in Him you shall be great....For what can a small tongue say towards the praise of the Great One? By saying, Beyond praise, he has spoken, and has given to imagination what it may conceive: as if saying, What I cannot utter, do thou reflect on; and when you shall have reflected, it will not be enough. What no man's thought utters, does any man's tongue utter? “The Lord is great, and cannot worthily be praised.” Let Him be praised, and preached: His honour declared, and His house built.
