Augustine of Hippo
Catena Aurea · Matthäusevangelium 13
Another parable put he forth unto them, saying, The kingdom of heaven is likened unto a man which sowed good seed in his field: But while men slept, his enemy came and sowed tares among the wheat, and went his way. But when the blade was sprung up, and brought forth fruit, then appeared the tares also. So the servants of the householder came and said unto him, Sir, didst not thou sow good seed in thy field; from whence then hath it tares? He said unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up? But he said, Nay; lest while ye gather up the tares, ye root up also the wheat with them. Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn.
(Quæst. in Matt. q. 12.) Or otherwise; When a man begins to be spiritual, discerning between things, then he begins to see errors; for he judges concerning whatsoever he hears or reads, whether it departs from the rule of truth; but until he is perfected in the same spiritual things, he might be disturbed at so many false heresies having existed under the Christian name, whence it follows, And the servants of the householder coming to him said unto him, Didst thou not sow good seed in thy field? whence then hath it tares? Are these servants then the same as those whom He afterwards calls reapers? Because in His exposition of the parable, He expounds the reapers to be the Angels, and none would dare to say that the Angels were ignorant who had sowed tares, we should the rather understand that the faithful are here intended by the servants. And no wonder if they are also signified by the good seed; for the same thing admits of different likenesses according to its different significations; as speaking of Himself He says that He is the door, he is the shepherd.
