In short: Men who are gifted for ministry and exercise genuine piety have been given those gifts not just for themselves but also to serve others. They ought not refuse the call out of desire for ease. The care of feeding the flock is the proof of loving it. Refusing to feed it is failing to love the chief Shepherd. Those who are gifted are obligated to serve others. They should not long only for a secret place of quiet, contemplation, and retreat but should also preach. In failing to minister they are guilty in proportion to the greatness of their gifts by which they could have been useful. – CSB
Of those who are able to profit others by virtuous example in supreme rule, but fly from it in pursuit of their own ease.
For there are some who are eminently endowed with virtues, and for the training of others are exalted by great gifts, who are pure in zeal for chastity, strong in the might of abstinence, filled with the feasts of doctrine, humble in the long-suffering of patience, erect in the fortitude of authority, tender in the grace of loving-kindness, strict in the severity of justice. Truly such as these, if when called they refuse to undertake offices of supreme rule, for the most part deprive themselves of the very gifts which they received not for themselves alone, but for others also; and, while they meditate their own and not another’s gain, they forfeit the very benefits which they desire to keep to themselves. For hence it was that the Truth said to His disciples, A city that is set on an hill cannot be hid: neither do they light a candle and put it under a bushel, but on a candlestick, that it may give light to all that are in the house (Matth. v. 15). Hence He says to Peter, Simon, Son of Jonas, lovest thou Me? (Joh. 21:15); and he, when he had at once answered that he loved, was told, If thou lovest Me, feed My sheep. If, then, the care of feeding is the proof of loving, whosoever abounds in virtues, and yet refuses to feed the flock of God, is convicted of not loving the chief Shepherd. Hence Paul says, If Christ died for all, then all died. And if He died for all, it remaineth that they which live should now no longer live unto themselves, but unto Him which died for them and rose again (2 Cor. v. 15). Hence Moses says (Deut. xxv. 5) that a surviving brother shall take to him the wife of a brother who has died without children, and beget children to the name of his brother; and that, if he haply refuse to take her, the woman shall spit in his face, and her kinsman shall loose the shoe from off one of his feet, and call his habitation the house of him that hath his shoe loosed. Now the deceased brother is He who, after the glory of the resurrection, said, Go tell My brethren (Matth. xxviii. 10). For He died as it were without children, in that He had not yet filled up the number of His elect. Then, it is ordered that the surviving brother shall have the wife assigned to him, because it is surely fit that the care of holy Church be imposed on him who is best able to rule it well. But, should he be unwilling, the woman spits in his face, because whosoever cares not to benefit others out of the gifts which he has received, the holy Church exprobrates even what he has of good, and, as it were, casts spittle on his face; and from one foot the shoe is taken away, inasmuch as it is written, Your feet shod in preparation of the Gospel of Peace (Ephes. vi. 15). If, then, we have the care of our neighbour as well as of ourselves upon us, we have each foot protected by a shoe. But he who, meditating his own advantage, neglects that of his neighbours, loses with disgrace one foot’s shoe. And so there are some, as we have said, enriched with great gifts, who, while they are ardent for the studies of contemplation only, shrink from serving to their neighbour’s benefit by preaching; they love a secret place of quiet, they long for a retreat for speculation. With respect to which conduct, they are, if strictly judged, undoubtedly guilty in proportion to the greatness of the gifts whereby they might have been publicly useful. For with what disposition of mind does one who might be conspicuous in profiting his neighbours prefer his own privacy to the advantage of others, when the Only-begotten of the supreme Father Himself came forth from the bosom of the Father into the midst of us all, that He might profit many?
Mtt. 5:15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.
Jn. 21:15 So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.
Mtt. 28:10 Then said Jesus unto them, Be not afraid: go tell my brethren that they go into Galilee, and there shall they see me.
Dt. 25:5-10 If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband’s brother shall go in unto her, and take her to him to wife, and perform the duty of an husband’s brother unto her. 6 And it shall be, that the firstborn which she beareth shall succeed in the name of his brother which is dead, that his name be not put out of Israel. 7 And if the man like not to take his brother’s wife, then let his brother’s wife go up to the gate unto the elders, and say, My husband’s brother refuseth to raise up unto his brother a name in Israel, he will not perform the duty of my husband’s brother. 8 Then the elders of his city shall call him, and speak unto him: and if he stand to it, and say, I like not to take her; 9 Then shall his brother’s wife come unto him in the presence of the elders, and loose his shoe from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that man that will not build up his brother’s house. 10 And his name shall be called in Israel, The house of him that hath his shoe loosed.
