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.
Balsamon. Those who from fear only and timidity deserted the faith, and then had an eye towards repentance, the canon punishes with three years’ exclusion, according to the parable of the fig-tree in the Gospels. For the Lord said, Three years I come to it seeking fruit, and find none; but the vine-dresser replies, Lord, let it alone this year also.
Zonaras. But those, he says, who having suffered no hardness, have deserted from fear only and timidity, in that they of their own accord have approached to wickedness, and then looked towards repentance, their case the parable of the fig-tree in the Gospels will exactly suit. Let them keep this before their eyes, and show forth for an equal period labours worthy of penitence, and they shall be profited; that is, after the fourth year. For the Lord said, Three years I come to it seeking fruit, and find none; and the vine-dresser answered, Lord, let it alone this year also.
