The episcopate is one, each part of which is held by each one for the whole. 3115 The Church also is one, which is spread abroad far and wide into a multitude by an increase of fruitfulness. As there are many rays of the sun, but one light; and many branches of a tree, but one strength based in its tenacious root; and since from one spring flow many streams, although the multiplicity seems diffused in the liberality of an overflowing abundance, yet the unity is still preserved in the source. Separate a ray of the sun from its body of light, its unity does not allow a division of light; break a branch from a tree,—when broken, it will not be able to bud; cut off the stream from its fountain, and that which is cut off dries up. Thus also the Church, shone over with the light of the Lord, sheds forth her rays over the whole world, yet it is one light which is everywhere diffused, nor is the unity of the body separated. Her fruitful abundance spreads her branches over the whole world. She broadly expands her rivers, liberally flowing, yet her head is one, her source one; and she is one mother, plentiful in the results of fruitfulness: from her womb we are born, by her milk we are nourished, by her spirit we are animated.
The spouse of Christ cannot be adulterous; she is uncorrupted and pure. She knows one home; she guards with chaste modesty the sanctity of one couch. She keeps us for God. She appoints the sons whom she has born for the kingdom. Whoever is separated from the Church and is joined to an adulteress, is separated from the promises of the Church; nor can he who forsakes the Church of Christ attain to the rewards of Christ. He is a stranger; he is profane; he is an enemy. He can no longer have God for his Father, who has not the Church for his mother. If any one could escape who was outside the ark of Noah, then he also may escape who shall be outside of the Church. The Lord warns, saying, “He who is not with me is against me, and he who gathereth not with me scattereth.” He who breaks the peace and the concord of Christ, does so in opposition to Christ; he who gathereth elsewhere than in the Church, scatters the Church of Christ. The Lord says, “I and the Father are one;” and again it is written of the Father, and of the Son, and of the Holy Spirit, “And these three are one.” And does any one believe that this unity which thus comes from the divine strength and coheres in celestial sacraments, can be divided in the Church, and can be separated by the parting asunder of opposing wills? He who does not hold this unity does not hold God’s law, does not hold the faith of the Father and the Son, does not hold life and salvation.
Christ gave us peace; He bade us be in agreement, and of one mind. He charged the bonds of love and charity to be kept uncorrupted and inviolate; he cannot show himself a martyr who has not maintained brotherly love. Paul the apostle teaches this, and testifies, saying, “And though I have faith, so that I can remove mountains, and have not charity, I am nothing. And though I give all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing. Charity is magnanimous; charity is kind; charity envieth not; charity acteth not vainly, is not puffed up, is not easily provoked, thinketh no evil; loveth all things, believeth all things, hopeth all things, endureth all things. Charity never faileth.” “Charity,” says he, “never faileth.” For she will ever be in the kingdom, she will endure for ever in the unity of a brotherhood linked to herself. Discord cannot attain to the kingdom of heaven; to the rewards of Christ, who said, “This is my commandment, that ye love one another, even as I have loved you:” he cannot attain who has violated the love of Christ by faithless dissension. He who has not charity has not God. The word of the blessed Apostle John is: “God,” saith he, “is love; and he that dwelleth in love dwelleth in God, and God dwelleth in him.” They cannot dwell with God who would not be of one mind in God’s Church. Although they burn, given up to flames and fires, or lay down their lives, thrown to the wild beasts, that will not be the crown of faith, but the punishment of perfidy; nor will it be the glorious ending of religious valour, but the destruction of despair.
