Matthew 21:23

But if the Lord come seeking fruit with temptations, and one be found having nought of righteousness but only a profession of faith, which is leaves without fruit, he is soon withered, losing even his seeming faith; and every disciple makes this fig tree to wither, by making it be seen that he is void of Christ, as Peter said to Simon, Thy heart is not right in the sight of God (Acts 8:21.) For it is better that a deceitful fig tree which is thought to be alive, yet brings forth no fruit, should be withered up at the word of Christ's disciples, than that by an imposture it should steal aawy innocent hearts. Also there is in every unbeliever a mountain great in proportion to his unbelief, which is removed by the words of Christ's disciples. But some one will say in opposition to this, that it was absurd to ask by what authority Jesus did these things. For that it could not be that He would answer, that He did these by the Devil's authority; and He would not tell them as it truly was, that He did them by His own power. If it should be said, that the rulers put this question to Him in order to deter Him from His proceedings; as when we say to one who is dealing with what is ours in a way which we do not like, we say to him, Who bade thee do this? meaning to deter him from what he is so doing;—if it is to be taken so, what means Christ's answer, Do you tell Me this, and I will tell you by what authority I do these things. Perhaps therefore, the place should be understood as follows. There are in the general two opposite powers, one on the side of God, the other on the side of the Devil; but of particular powers there are many; for it was not one and the same power that wrought in all the Prophets to enable them to do miracles, but one in these, another in those; and, it may be, for lesser things a lesser power, for greater things a greater power. The Chief Priests had seen Jesus working many miracles, whereupon they desired to know the special degree and properties of that power which wrought in Him. For others who have wrought miracles wrought them at first in one power, and afterwards when more advanced in another and greater power; but the Saviour wrought all in one power, that which He received of the Father. But because they were not worthy to hear such mysteries, therefore He gives them no answer, but on the contrary put a question to them.

But the boastful and arrogant Jews, wishing to interrupt His teaching, came unto Him, and asked, "By what authority doest thou these things?" For since they could not object against the miracles, they bring forward against Him the correction of the traffickers in the temple. And this in John also they appear to ask, although not in these words, but with the same intent. For there too they say, "What sign showest thou unto us? seeing that thou doest these things." But there He answers them, saying, "Destroy this temple, and I in three days will raise it up," whereas here He drives them into a difficulty. Whence it is manifest, that then indeed was the beginning and prelude of the miracles, but here the end. But what they say is this: Hast thou received the teacher's chair? Hast thou been ordained a priest, that thou didst display such authority? it is said. And yet He had done nothing implying arrogance, but had been careful for the good order of the temple, yet nevertheless having nothing to say, they object against this. And indeed when He cast them out, they did not dare to say anything, because of the miracles, but when He showed Himself, then they find fault with Him.

Or in these words they urge the same cavil as above, when they said, He casteth out demons through Beelzebub the Prince of the demons. (Mat. 12:24.) For when they say, By what authority doest thou these things? they doubt concerning the power of God, and would have it understood that the things He does are of the Devil. But when they add, Who gave thee this authority? they most clearly deny the Son of God, whom they suppose to work miracles, not by His own, but by others' strength.

The Priests were tormented with jealousy, because they had seen Christ entering the Temple in great glory. And not being able to master the fire of jealousy which burnt in their breasts, they break forth in speech. By that they add, Or who gave thee this authority? they show that there be many persons who give power to men, whether corporal or spiritual! as though they had said, Thou art not come of a priestly family; the Senate has not conferred on Thee this power, neither has Cæsar granted it. But had they believed that all power is from God, they would never have asked, Who gave thee this authority? For every man judges of others by himself. The fornicator thinks that none are chaste; the chaste does not readily suspect any of fornication; he who is not a Priest of God, thinks no man's Priesthood to be of God.
