Theophylact of Bulgaria
But each one of us also is a fig tree planted in the vineyard of God, that is, in the Church, or in the world.
Our nature yields no fruit though three times sought for; once indeed when we transgressed the commandment in paradise; the second time, when they made the molten calf under the law; thirdly, when they rejected the Saviour. But that three years’ time must be understood to mean also the three ages of life, boyhood, manhood, and old age.
Or the master of the household is God the Father, the dresser is Christ, who will not have the fig tree cut down as barren, as if saying to the Father, Although through the Law and the Prophets they gave no fruit of repentance, I will water them with My sufferings and teaching, and perhaps they will yield us fruits of obedience.
