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.
(Ep. 93. 17.) This indeed was at first my own opinion, that no man was to be driven by force into the unity of Christ; but he was to be led by discourse, contended with in controversy, and overcome by argument, that we might not have men feigning themselves to be Catholics whom we knew to be declared heretics. But this opinion of mine was overcome not by the authority of those who contradicted me, but by the examples of those that shewed it in fact; for the tenor of those laws in enacting which Princes serve the Lord in fear, has had such good effect, that already some say, This we desired long ago; but now thanks be to God who has made the occasion for us, and has cut off our pleas of delay. Others say, This we have long known to be the truth; but we were held by a kind of old habit, thanks be to God who has broken our chains. Others again; We knew not that this was true, and had no desire to learn it, but fear has driven us to give our attention to it, thanks be to the Lord who has banished our carelessness by the spur of terror. Others, We were deterred from entering in by false rumours, which we should not have known to be false had we not entered in, and we should not have entered in had we not been compelled; thanks be to God who has broken up our preaching by the scourge of persecution, and has taught us by experience how empty and false things lying fame had reported concerning His Church. Others say, We thought indeed that it was of no importance in what place we held the faith of Christ; but thanks be to the Lord who has gathered us together out of our division, and has shewn us that it is consonant to the unity of God that He should be worshipped in unity. Let then the Kings of the earth shew themselves the servants of Christ by publishing laws in Christ’s behalf.
