13 Accordingly, brethren, when you hear the Lord saying, “Where I am, there shall also my servant be,” do not think merely of good bishops and clergymen. But be yourselves also in your own way serving Christ, by good lives, by giving alms, by preaching His name and doctrine as you can; and every father of a family also, be acknowledging in this name the affection he owes as a parent to his family. For Christ's sake, and for the sake of life eternal, let him be warning, and teaching, and exhorting, and correcting all his household; let him show kindliness, and exercise discipline; and so in his own house he will be filling an ecclesiastical and kind of episcopal office, and serving Christ, that he may be with Him for ever. For even that noblest service of suffering has been rendered by many of your class; for many who were neither bishops nor clergy, but young men and virgins, those advanced in years with those who were not, many married persons both male and female, many fathers and mothers of families, have served Christ even to the laying down of their lives in martyrdom for His sake, and have been honored by the Father in receiving crowns of exceeding glory.
