Let us praise the Lord both in voice, and in understanding, and in good works; and, as this Psalm exhorteth, let us sing unto Him a new song. It beginneth: "Sing ye to the Lord a new song. His praise is in the Church of the Saints" (ver. 1). The old man hath an old song, the new man a new song. The Old Testament is an old song, the New Testament a new song. In the Old Testament are temporal and earthly promises. Whoso loveth earthly things singeth an old song: let him that desireth to sing a new song, love the things of eternity. Love itself is new and eternal; therefore is it ever new, because it never groweth old. ...And this song is of peace, this song is of charity. Whoso severeth himself from the union of the saints, singeth not a new song; for he hath followed old strife, not new charity. In new charity what is there? Peace, the bond of an holy society, a spiritual union, a building of living stones. Where is this? Not in one place, but throughout the whole world. This is said in another Psalm, "Sing unto the Lord, all the earth." From this is understood, that he who singeth not with the whole earth, singeth an old song, whatever words proceed out of his mouth. ...We have already said, brethren, that all the earth singeth a new song. He who singeth not with the whole earth a new song, let him sing what he will, let his tongue sound forth Halleluia, let him utter it all day and all night, my ears are not so much bent to hear the voice of the singer, but I seek the deeds of the doer. For I ask, and say, "What is it that thou singest?" He answereth, "Halleluia." What is "Halleluia"? "Praise ye the Lord." Come, let us praise the Lord together. If thou praisest the Lord, and I praise the Lord, why are we at variance? Charity praiseth the Lord, discord blasphemeth the Lord." ...

O brothers, o sons, o Catholic offspring, o holy and celestial seeds, o regenerated in Christ and born from above, listen to me, rather through me: Sing to the Lord a new song. "Look," you say, "I sing." You sing, indeed you sing, I hear. But let life not contradict the testimony of the tongue. Sing with voices, sing with hearts, sing with mouths, sing with lifestyles: Sing to the Lord a new song. Are you asking what you should sing about him whom you love? Without a doubt, you want to sing about him whom you love. You seek his praises to sing. You have heard: Sing to the Lord a new song. Are you seeking praises? His praise is in the congregation of the saints. The praise of singing is the singer himself. Do you want to speak praises to God? Be yourselves what you say. You are his praise if you live well. For his praise is not in the synagogues of the Jews, not in the madness of the pagans, not in the errors of the heretics, not in the applause of the theaters. Are you looking for where it is? Pay attention, be yourselves: His praise is in the congregation of the saints.

"Let Israel rejoice in Him who made Him" [Psalm 149:2]. What is, "Israel"? "Seeing God." He who sees God, rejoices in Him by whom he was made. What is it then, brethren? We have said that we belong to the Church of the saints: do we already see God? And how are we Israel, if we see not? There is one kind of sight belonging to this present time; there will be another belonging to the time hereafter: the sight which now is, is by faith; the sight which is to be will be in reality. If we believe, we see; if we love, we see: see what? God. Ask John: "God is love;" [1 John 4:16] let us bless His holy Name, and rejoice in God by rejoicing in love. Whoso has love, why send we him afar to see God? Let him regard his own conscience, and there he sees God...."And let the sons of Sion exult in their King." The sons of the Church are Israel. For Sion indeed was one city, which fell: amid its ruins certain saints dwelt after the flesh: but the true Sion, the true Jerusalem (for Sion and Jerusalem are one), is "eternal in the heavens," [2 Corinthians 5:1] and is "our mother." [Galatians 4:26] She it is that has given us birth, she is the Church of the saints, she has nourished us, she, who is in part a pilgrim, in part abiding in the heavens. In the part which abides in heaven is the bliss of angels, in the part which wanders in this world is the hope of the righteous. Of the former is said, "Glory to God in the highest;" of the latter, "and on earth peace to men of good will." [Luke 2:14] Let those then who, being in this life, groan, and long for their country, run by love, not by bodily feet; let them seek not ships but wings, let them lay hold on the two wings of love. What are the two wings of love? The love of God, and of our neighbour. For now we are pilgrims, we sigh, we groan. There has come to us a letter from our country: we read it to you. "And the sons of Sion shall exult in their King." The Son of God, who made us, was made one of us: and He rules us as our King, because He is our Creator, who made us. But He by whom we were made is the same as He by whom we are ruled, and we are Christians because He is Christ. He is called Christ from Chrism, that is, Anointing....Give to the Priest somewhat to offer. What could man find which he could give as a clean victim? What victim? What clean thing can a sinner offer? O unrighteous, O sinful man, whatever you offer is unclean, and somewhat that is clean must be offered for you....Let then the Priest that is clean offer Himself, and cleanse you. This is what Christ did. He found in man nothing clean for Him to offer for man: He offered Himself as a clean Victim. Happy Victim, true Victim, spotless Offering. He offered not then what we gave Him; yea rather, He offered what He took of us, and offered it clean. For of us He took flesh, and this He offered. But where took He it? In the womb of the Virgin Mary, that He might offer it clean for us unclean. He is our King, He is our Priest, in Him let us rejoice.

"Let them praise His Name in chorus" [Psalm 149:3]. What means "chorus"? Many know what a "chorus" is: nay, as we are speaking in a town, almost all know. A "chorus" is the union of singers. If we sing "in chorus," let us sing in concord. If any one's voice is out of harmony in a chorus of singers, it offends the ear, and throwes the chorus into confusion. If the voice of one echoing discordantly troubles the harmony of them who sing, how does the discord of heresy throw into confusion the harmony of them who praise. The whole world is now the chorus of Christ. The chorus of Christ sounds harmoniously from east to west. "Let them sing a psalm unto Him with timbrel and psaltery." Wherefore takes he to him the "timbrel and psaltery"? That not the voice alone may praise, but the works too. When timbrel and psaltery are taken, the hands harmonize with the voice. So too do thou, whenever you sing, "Halleluia," deal forth your bread to the hungry, clothe the naked, take in the stranger: then does not only your voice sound, but your hand sounds in harmony with it, for your deeds agree with your words. You have taken to you an instrument, and your fingers agree with your tongue. Nor must we keep back the mystical meaning of the "timbrel and psaltery." On the timbrel leather is stretched, on the psaltery gut is stretched; on either instrument the flesh is crucified. How well did he "sing a psalm on timbrel and psaltery," who said, "the world is crucified unto me, and I unto the world"? [Galatians 6:14] This psaltery or timbrel He wishes you to take up, who loves a new song, who teaches you, saying to you, "Whosoever wills to be My disciple, let him deny himself, and take up his cross, and follow Me." [Matthew 16:24] Let him not set down his psaltery, let him not set down his timbrel, let him stretch himself out on the wood, and be dried from the lust of the flesh. The more the strings are stretched, the more sharply do they sound. The Apostle Paul then, in order that his psaltery might sound sharply, what said he? "Stretching forth unto those things which are before," etc. [Philippians 3:13] He stretched himself: Christ touched him; and the sweetness of truth sounded.

"The saints shall exult in glory" [Psalm 149:5]. I would say somewhat important about the glory of the saints. For there is no one who loves not glory. But the glory of fools, popular glory as it is called, has snares to deceive, so that a man, influenced by the praises of vain men, shall be willing to live in such fashion as to be spoken of by men, whosoever they be, in whatsoever way. Hence it is that men, rendered mad, and puffed up with pride, empty within, without swollen, are willing ever to ruin their fortunes by bestowing them on stage-players, actors, men who fight with wild beasts, charioteers. What sums they give, what sums they spend! They lavish the powers not only of their patrimony, but of their minds too. They scorn the poor, because the people shouts not that the poor should be given to, but the people do shout that the fighter with wild beasts be given to. When then no shout is raised to them, they refuse to spend; when madmen shout to them, they are mad too: nay, all are mad, both performer, and spectator, and the giver. This mad glory is blamed by the Lord, is offensive in the eyes of the Almighty....Thou choosest to clothe the fighter with wild beasts, who may be beaten, and make you blush: Christ is never conquered; He has conquered the devil, He has conquered for you, and to you, and in you; such a conqueror as this you choose not to clothe. Wherefore? Because there is less shouting, less madness about it. They then who delight in such glory, have an empty conscience. Just as they drain their chests, to send garments as presents, so do they empty their conscience, so as to have nothing precious therein.

But the saints who "exult in glory," no need is there for us to say how they exult: just hear the verse of the Psalm which follows: "The saints shall exult in glory, they shall rejoice in their beds:" not in theatres, or amphitheatres, or circuses, or follies, or market places, but "in their chambers." What is, "in their chambers"? In their hearts. Hear the Apostle Paul exulting in his closet: "For this is our glory, the testimony of our conscience." [2 Corinthians 1:12] On the other hand, there is reason to fear lest any be pleasing to himself, and so seem to be proud, and boast of his conscience. For every one ought to exult with fear, for that wherein he exults is God's gift, not his own desert. For there be many that please themselves, and think themselves righteous; and there is another passage which goes against them, which says, "Who shall boast that he has a clean heart, and that he is pure from sin?" [Proverbs 20:9] There is then, so to speak, a limit to glorying in our conscience, namely, to know that your faith is sincere, your hope sure, your love without dissimulation. "The exultations of God are in their mouths" [Psalm 149:6]. In such wise shall they "rejoice in their closets," as not to attribute to themselves that they are good, but praise Him from whom they have what they are, by whom they are called to attain to what they are not, and from whom they hope for perfection, to whom they give thanks, because He has begun.

Christ is truly the Son of that God Who gave the Law; after the example of the blessings pronounced in the Law, did Himself pronounce the blessings of them that are saved; and also after the cursings of the Law, He now sets forth a woe against sinners; Woe unto you, Scribes and Pharisees, hypocrites. They who allow that it is compatible with goodness to utter these denunciations against sinners, should understand that the purpose of God is the same in the cursings of the Law. Both the cursing there and the woe here fall upon the sinner not from Him who denounces, but from themselves who commit the sins which are denounced, and worthily bring upon themselves the inflictions of God’s discipline, appointed for the turning of men to good. So a father rebuking a son utters words of cursing, but does not desire that he should become deserving of those curses, but rather that he should turn himself from them. He adds the cause of this woe, Ye shut up the kingdom of heaven against men; for ye neither go in yourselves, nor suffer them that are entering to go in. These two commandments are by nature inseparable; because not to suffer others to enter in, is of itself enough to keep the hinderer out.

The Pharisees and the Scribes then would neither enter in, nor hear Him who said, By me if any man enter in he shall be saved; (John 10:9.) nor would they suffer those to enter in, who were able to have believed through the things which had been spoken before by the Law and the Prophets concerning Christ, but shut up the door with every kind of device to deter men from entering. Also they detracted from His teaching, denied all prophecy concerning Him, and blasphemed every miracle as deceitful, or wrought by the Devil. All who in their evil conversation set an example of sinning to the people, and who commit injustice, offending the weak, seem to shut up the kingdom of heaven before men. And this sin is found among the people, and chiefly among the doctors, when they teach men what the Gospel righteousness requires of them, but do not what they teach. But those who both teach and live well open to men the kingdom of heaven, and both enter in themselves, and invite others to enter in. Many also will not suffer those who are willing to enter into the kingdom of heaven, when they without reason excommunicate out of jealousy others who are better than themselves; thus they refuse them entrance, but these of sober spirit, overcoming by their patience this tyranny, although forbidden, yet enter in and inherit the kingdom. Also they who with much rashness have set themselves to the profession of teaching before they have learned, and following Jewish fables, detract from those who search out the higher things of Scripture; these do, as far as in them lies, shut out men from the kingdom of heaven.

Now an oath is in confirmation of somewhat that has been spoken. The oath here then may signify testimony of Scripture which we produce in confirmation of that word which we speak. So that Divine Scripture is the temple of God, the gold is the meaning which it contains. As the gold which is outside the Temple is not sanctified, so all thoughts which are without divine Scripture, however admirable they may seem, are not hallowed. We ought not therefore to bring any speculations of our own for the confirmation of doctrine, unless such as we can shew are hallowed by being contained in divine Scripture. The altar is the human heart, which is the chief thing in man. The offerings and gifts that are hid upon the altar, are every thing which are done in the heart, as to pray, to sing, to do alms, to fast. Every offering of a man then is sanctified by his heart, by which the offering is made. There cannot therefore be a more honourable offering than the heart of man, out of which the offering proceeds. If then one’s conscience does not smite him, he has confidence towards God, not by reason of his gifts, but so to speak because he has rightly ordered the altar of his heart. Thirdly, we may say that over the temple, that is over every Scripture, and over the altar, that is over every heart, there is a certain meaning which is called the Heaven, the throne of God Himself, in which we shall be able to see the things that are revealed face to face, when that which is perfect is come.
