Pseudo-Chrys.: Those who are to be judged in this cause, He applies to as judges, that condemning themselves they might be shewn to be unworthy to be acquitted by any other. It is high confidence of the justness of a cause, that will entrust it to the decision of an adversary. But He veils the allusion to them in a parable, that they might not perceive that they were passing sentence upon themselves; "A certain man had two sons." Who is he but God, who created all men, who being by nature Lord of all, yet would rather be loved as a father, than feared as a Lord. The elder son was the Gentile people, the younger the Jews, since from the time of Noah there had been Gentiles. And he came to the [p. 725] first, and said, Son, go work to day in my vineyard. To day," i.e. during this age. He spoke with him, not face to face as man, but to his heart as God, instilling understanding through the senses. To work in the vineyard is to do righteousness; for to cultivate the whole thereof, I know not that any one man is sufficient.

Jerome: But when, at the coming of the Saviour, the Gentile people, having done penitence, laboured in God's vineyard, and atoned by their labour for the obstinacy of their refusal, this is what is said, "But afterward he repented, and went." The second son is the Jewish people who made answer to Moses, "All that the Lord hath said unto us we will do." [Ex 24:3]

Raban.: Yet the kingdom of God may be understood of the Gentiles, or of the present Church, in which the Gentiles go before the Jews, because they were more ready to believe.
Origen: Notwithstanding, the Jews are not shut out that they should never enter into the kingdom of God; but, "when the fulness of the Gentiles shall have entered in, then all Israel shall be saved."

Pseudo-Chrys.: This He brings in because the Priests had asked not in order to learn, but to tempt Him. But of the common folk many had believed; and for that reason He brings forward the parable of the two sons, shewing them therein that the common sort, who from the first professed secular lives, were better than the Priests who from the first professed the service of God, inasmuch as the people at length turned repentant to God, but the Priests impenitent, never left off to sin against God. And the elder son represents the people; because the people is not for the sake of the Priests, but the Priests are for the sake of the people.
