Consequently, heretics and schismatics, separated from the unity of this Body, are able to receive the same Sacrament, but with no benefit to themselves; indeed, more to their own harm, in that they are judged the more severely rather than being liberated.
In what is necessary, unity; in what is not necessary, liberty and in all things charity.
By faithfulness we are collected and wound up into unity within ourselves, whereas we had been scattered abroad in multiplicity.
O Sacrament of Love! O sign of Unity! O bond of Charity! He who would have Life finds here indeed a Life to live in and a Life to live by.
The Head and the body are Christ wholly and entirely. The Head is the only begotten Son of God, the body is His Church; the bridegroom and the bride, two in one flesh. All who dissent from the Scriptures concerning Christ, although they may be found in all places in which the Church is found, are not in the Church; and again all those who agree with the Scriptures concerning the Head, and do not communicate in the unity of the Church, are not in the Church.
There is nothing more serious than the sacrilege of schism because there is no just cause for severing the unity of the Church.
