Knowing our roles in the Church
However, a man who has a wife and wishes to become a priest is taking his earthly marriage and entering into a more perfect marriage in union with God. Corinthians also says that each man as responsible to God, should remain in the situation God called him to.
Single men were called to a celibate life in Christ. Some of the apostles were married prior to being called to the priesthood, hence the reason the Scripture says let a bishop have only one wife. In the history and traditions of the Church, no priest ever got married, but married men could become priests.
