VI. Cyprian, also, after the example of Paul, deduces the origin of all ecclesiastical concord from the supreme bishopric of Christ. He afterwards subjoins, “There is but one Church, which is widely extended into a multitude by the offspring of its fertility; just as there are many rays of the sun, but the light is one; and a tree has many branches, but only one trunk, fixed on a firm root. And when many rivers issue from one source, though by its exuberant abundance the stream is multiplied into numerous currents, yet the unity of the fountain still remains. Separate a ray from the body of the sun, and its unity sustains no division. Break off a branch from a tree, and the broken branch can never bud. Cut off a river from the source, and it immediately dries up. So the Church, overspread with the light of the Lord, is extended over the whole world: yet it is one and the same light which is universally diffused.” No representation could be more elegant to express that inseparable connection which subsists between all the members of Christ. We see how he continually recalls us to the fountain-head. Therefore he pronounces the origin of heresies and schisms to be, that men neither return to the source of truth, nor seek the Head, nor attend to the doctrine of the heavenly Master. Now, let the Romanists exclaim that we are heretics, because we have withdrawn from their church; while the sole cause of our secession has been, that theirs cannot possibly be the pure profession of the truth. I say nothing of their having expelled us with anathemas and execrations. But this reason is more than sufficient for our exculpation, unless they are determined to pronounce sentence of schism also against the apostles, with whom we have but one common cause. Christ, I say, foretold to his apostles, that for his name’s sake they should be cast out of the synagogues.[793] Now, those synagogues, of which he spoke, were then accounted legitimate Churches. Since it is evident, then, that we have been cast out, and we are prepared to prove that this has been done for the name of Christ, it is necessary to inquire into the cause, before any thing be determined respecting us, either on one side or the other. But this point I readily relinquish to them. It is sufficient for me that it was necessary for us to withdraw from them, in order to approach to Christ.
