episcopate (seen as a fuller form of priesthood than the presbyterate) for the celibate. Some Catholic scholars, such as Jesuits Peter Fink and George T. Dennis of Catholic University of America, have argued that we cannot know if priests in early Christianity practised sexual abstinence. Dennis says "there is simply no clear evidence of a general tradition or practice, much less of an obligation, of priestly celibacy-continence before the beginning of the fourth century." Fink says that a primary book used to support apostolic origins of priestly celibacy "remains a work of interpretation. There are underlying premises that seem to hold firm in this book but which would not stand up so comfortably to historical scrutiny." The earliest textual evidence of the forbidding of marriage to clerics and the duty of those already married to abstain from sexual contact with their wives is in the fourth-century decrees of the Synod of Elvira and the later Council of Carthage (390). According to some writers, this presumed a previous norm, which was being flouted in practice. Synod of Elvira (c. 305) (Canon 33): "It is decided that marriage be altogether prohibited to bishops, priests, and deacons, or to all clerics placed in the ministry, and that they keep away from their wives and not beget children; whoever does this shall be deprived of the honor of the clerical office." Council of Carthage (390) (Canon 3): "It is fitting that the holy bishops and priests of God as well as the Levites, i.e. those who are in the service of the divine sacraments, observe perfect continence, so that they may obtain in all simplicity what they are asking from God; what the Apostles taught and what antiquity itself observed, let us also endeavour to keep.... It pleases us all that bishop, priest and deacon, guardians of purity, abstain from conjugal intercourse with their wives, so that those who serve at the altar may keep a perfect chastity." Among the early Church statements on the topic of sexual continence and celibacy are the Directa and Cum in unum decretals of Pope Siricius (c. 385), which asserted that clerical sexual abstinence was an apostolic practice that must be followed by ministers of the church. The writings of Saint Ambrose (died 397) also show that the requirement that priests, whether married or celibate, should be continent was the established rule. To the married clergy who, "in
