The Canonical Epistle, with the Commentaries of Theodore Balsamon and John Zonaras 3Canon III.

But as for those who have suffered none of these things, and have shown no fruit of faith, but of their own accord have gone over to wickedness, being betrayed by fear and cowardice, and now come to repentance, it is necessary and convenient to propose the parable of the unfruitful fig-tree, as the Lord says: "A certain man had a fig-tree planted in his vineyard; and he came and sought fruit thereon, and found none. Then said he unto the dresser of his vineyard, Behold, these three years I come seeking fruit on this fig-tree, and find none: cut it down; why cumbereth it the ground? And he answering, said unto him, Lord, let it alone this year also, till I shall dig about it, and dung it. And if it bear fruit, well; and if not, then after that thou shalt cut it down." Keeping this before their eyes, and showing forth fruit worthy of repentance, after so long an interval of time, they will be profited.
