Augustine of Hippo

(ad Honor. Ep. clxxx.) A servant of Christ, and minister of His Word and Sacraments, may flee from city to city, when he is specially aimed at by the persecutors, apart from his brethren; so that his flight does not leave the Church destitute. But when all, i. e. Bishops, Clerics, and Laics, are in danger in common, let not those who need assistance be deserted by those who should give it. Let all flee together if they can, to some place of security; but, if any are obliged to stay, let them not be forsaken by those who are bound to minister to their spiritual wants. Then, under pressing persecution, may Christ’s ministers flee from the place where they are, when none of Christ’s people remain to be ministered to, or when that ministry may be fulfilled by others who have not the same cause for flight. But when the people stay, and the ministers flee, and the ministry ceases, what is this but a damnable flight of hirelings, who care not for the sheep?
