The early church fathers expressed their qualified approval of digamy and maintained the superiority of widowhood over second marriage. Within this general framework, they had varying degrees of reservation. Tertullian (c. 160-220) addressed An Exhortation to Chastity to a friend who had been recently widowed, discouraging him from remarriage and explaining that, although second marriage was tolerated by the church, it was merely an objectionable expedient to safeguard the weak against temptation. Saint Cyril of Jerusalem (c. 315-386), however, shows more leniency towards digamists: “Those who are once married, let them not hold in contempt those who have accommodated themselves to a second marriage. Continence is a good and wonderful thing; but still, it is permissible to enter upon a second marriage.” (Catechetical Lectures 4.26). Saint Ambrose of Milan (c. 339-397) strikes a note of reserve in his attitude towards digamy: “What we suggest by way of counsel we do not command as a precept . . . . We do not prohibit second marriages, but neither do we recommend them” (The Widows 11.68).
