John Calvin Commentary Luke 22:38

"And they said, Lord, behold, here are two swords. And he said unto them, It is enough." — Luke 22:38 (ASV)

Lord, look, here are two swords. It was truly shameful and stupid ignorance that the disciples, after having been so often informed about bearing the cross, imagined that they must fight with swords of iron. When they say that they have two swords, it is uncertain whether they mean that they are well prepared against their enemies or complain that they are ill provided with arms. It is evident, at least, that they were so stupid as not to think of a spiritual enemy.

As for the inference which the Doctors of Canon Law draw from these words — that their mitered bishops have a double jurisdiction — it is not only an offensive allegory but a detestable mockery by which they ridicule the word of God. And it was necessary that the slaves of Antichrist should fall into such madness, of openly trampling underfoot, by sacrilegious contempt, the sacred oracles of God.
