Why does James, who received the episcopate in Jerusalem, not begin the speech, but yield to Peter the right to speak to the people?
Because he was filled with humility. At that time they thought of nothing human, but had the common benefit in view.
For the same reason the Apostles yield the chair to him. They do not rival him or dispute with him.
"To go to his own place." The place that Matthias was worthy to occupy is called by Luke his own, or proper, place.
For just as Judas, even before he fell from it, had already been estranged from this place from the time he fell sick with the disease of avarice and betrayal, so also Matthias' place became his possession beforehand.
It became his from the time he made himself worthy of such a gift, even before he occupied it.
Why did they prefer election by lot? Because they did not yet consider themselves worthy to learn this by some sign. The Holy Spirit had not yet come down upon them.
Nor was there need of a sign, for the lot had great significance. In the case of Jonah, neither prayer nor the men's wisdom helped to determine the right judgment. Rather, the lot had great force.
How much more was this true in the present case.
Again, "to his own place" means that each man prepares for himself either a good or an evil place by his own deeds.
Thus, when Luke says this, he means that Judas went to his own evil place, which he had prepared for himself by betraying Jesus.
Places are not good or evil for us by nature. Rather, we prepare a place for ourselves by our own deeds.
Thus, because the Hebrew midwives feared God, "He made them houses" (Ex 1:21). The ungodly hear this: "Walk in the light of your fire, and in the flame which you have kindled" (Is 50:11).
The word "place" has many meanings. Among other things, it signifies an office. Thus we speak of the place of a bishop or of a presbyter.
The same may be seen from the opposite side, according to how each man prepares his own place by his deeds.
Thus one may have the place of a false teacher and false apostle, as also of a tyrant and author of other criminal deeds.
Therefore, since Judas, carried away by the passion of avarice, occupied the place of betrayer, it is rightly said of him: "to go to his own place."
Having lost, by his deeds, his place in the company of the Apostles, he prepared his own place for himself.
