"This sacrament of unity, this bond of concord inseparably cohering, is signified in the place in the Gospel where the coat of our Lord Jesus Christ is in nowise parted or cut, but is received a whole garment, by them who cast lots who should rather wear it, and is possessed as an inviolate and individual robe. The divine scripture thus speaks: But for the coat, because it was not sewed, but woven from the top throughout, they said one to another, Let us not rend it, but cast lots whose it shall be. It has with it a unity descending from above, as coming, that is, from heaven and from the Father; which it was not for the receiver and owner in anywise to sunder, but which he received once for all and indivisibly as one unbroken whole. He cannot own Christ's garment who splits and divides Christ's Church. On the other hand, when on Solomon's death his kingdom and people were split in parts, Ahijah the prophet, meeting King Jeroboam in the field, rent his garment into twelve pieces, saying: Take thee ten pieces; for thus saith the Lord: Behold, I will rend the kingdom out of the hand of Solomon, and will give ten tribes to thee; and two tribes shall be to him for my servant David's sake, and for Jerusalem, the city which I have chosen, to place my name there. When the twelve tribes of Israel were torn asunder, the prophet Ahijah rent his garment. But because Christ's people cannot be rent, His coat, woven and conjoined throughout, was not divided by those to whom it fell. Individual, conjoined, coentwined, it shows the coherent concord of our people who put on Christ. In the sacrament and sign of His garment, He has declared the unity of His Church.

"Who, then, is the criminal and traitor, who so inflamed by the madness of discord, as to think aught can rend, or to venture on rending God's unity, the Lord's garment, Christ's Church? He Himself warns us in His Gospel and teaches, saying: And there shall be one Fold and one Shepherd.... Think you that any can stand and live who withdraws from the Church, and forms for himself new homes and different domiciles?... Believers have no house but the Church only. This house, this hostelry of unanimity, the Holy Spirit designs and betokens in the Psalms, thus speaking: God who makes men to dwell with one mind in a house. In the house of God, in the Church of Christ, men dwell with one mind, and persevere in concord and simplicity." To this he adds: "There is one God, and one Christ, and His Church one, and the Faith one, and one the people joined into the solid unity of a body by the cement of concord. Unity cannot be sundered, nor can one body be divided by a dissolution of its structure, nor be severed into pieces with torn and lacerated vitals. Parted from the womb nothing can live and breathe in its separated state: it loses its principle of health;" for "charity will ever exist in the kingdom; she will abide evermore in the unity of a brotherhood which entwines itself around her."
