... on the use of "figures" in speaking of Christian truth
... and what the saints are to be compared to:
For why is it, I ask, that if any one says that there are holy and just men whose life and conversation the Church of Christ uses as a means of redeeming those who come to it from all kinds of superstitions, and making them through their imitation of good men members of its own body;
men who, as good and true servants of God, have come to the baptismal font laying down the burdens of the world, and who rising thence do, through the implanting of the Holy Spirit, yield the fruit of a two-fold love, a love, that is, of God and their neighbor;--
how is it, I say, that if a man says this, he does not please his hearer so much as when he draws the same meaning from that passage in Canticles, where it is said of the Church, when it is being praised under the figure of a beautiful woman, "Thy teeth are like a flock of sheep that are shorn which came up from the washing, whereof every one bears twins, and none is barren among them?" (Song of Solomon)
Does the hearer learn anything more than when he listens to the same thought expressed in the plainest language, without the help of this figure? And yet, I don't know why, I feel greater pleasure in contemplating holy men, when I view them as the teeth of the Church, tearing men away from their errors, and bringing them into the Church's body, with all their harshness softened down, just as if they had been torn off and masticated by the teeth.
It is with the greatest pleasure, too, that I recognize them under the figure of sheep that have been shorn, laying down the burdens of the world like fleeces, and coming up from the washing, i.e., from baptism, and all bearing twins, i.e., the twin commandments of love, and none among them barren in that holy fruit.
