Luke 13:33

But because the Pharisees thought that He who was the Lord of hosts, feared the hand of Herod. He refutes this, saying, Nevertheless I must walk to day and to morrow, and the day following. When He says must, He by no means implies a necessity imposed upon Him, but rather that He walked where He liked according to the inclination of His will, until He should come to the end of the dreadful cross, the time of which Christ shows to be now drawing near, when He says, To day and to morrow.

Nevertheless, I must walk today and tomorrow, and the next day, for it is not possible for a prophet to perish outside of Jerusalem. Therefore, what he says, I cast out demons, and accomplish healings today and tomorrow, and on the third day I am perfected (Luke XIII), is referred to his body which is the Church. For demons are cast out, when the Gentiles believe in him, forsaking ancestral superstitions: and healings are accomplished, when life is lived according to his precepts, after renouncing the devil and this world until the end of the resurrection. By which, as if on the third day, it will be perfected to fullness like the angels, that is, the Church will be perfected through the immortality of the body.

Let us inquire into what is written in Luke, the Lord saying: "because it cannot be that a prophet perish outside Jerusalem." If, then, "it cannot be that a prophet perish outside Jerusalem," that is, be killed, you will ask whether after the destruction of Jerusalem there is now no prophet, lest perhaps the one who is killed "outside Jerusalem" should, being a prophet, prove the word of Christ false. But if the scriptures compel us — on account of Agabus and the daughters of Philip the evangelist (not on account of the false prophets of Phrygia) — let us inquire whether perhaps every righteous person is in Jerusalem and not "outside Jerusalem," since "it cannot be" that the one who is outside Jerusalem be afflicted with sufferings for the sake of the word. But that Jerusalem which is free from the servitude of sin, which is above in its manner of life, "which is our mother," does not kill the prophets nor stone those who are sent to her. It is another matter that, after the likeness of that Jerusalem which killed and stoned the prophets, frequently there are certain persons set up in this Jerusalem, unskilled and not fearing God, who (as far as in them lies) kill and stone, with words uttered without judgment, men advanced in word and in life — men who indeed do not abandon the canon of the churches, but on account of the profundity of their doctrines are held suspect by those who are accustomed to say certain novel things and do not attend to the "sound word" of our Lord Jesus Christ.
