Above all let him not have greater solicitude for fleeting, earthly and perishable things, and so overlook or undervalue the salvation of the souls committed to him; but let him always remember that he has undertaken the government of souls and will have to give an account of them. And if he be tempted to complain of lack of means, let him remember the words: Seek ye first the kingdom of God and his justice, and all these things shall be added unto you.1 And again: They that fear him lack nothing.2 And let him know that he who has undertaken the government of souls, must prepare himself to render an account of them. And whatever number of brethren he knows he has under his care, let him regard it as certain that he will have to give the Lord an account of all these souls in the Day of Judgement, and certainly of his own soul also. And thus, fearing always the examination which the shepherd will have to face for the sheep entrusted to him, and anxious regarding the account which will have to be given for others, he is made solicitous for his own sake also; and while by his admonitions helping others to amend, he himself is cleansed of his faults.
