Because the role of the Christian leader is to preach, teach, act as a shepherd, [and] be an example in personal and family life, the New Testament properly insists that he must not be a new convert nor a young man. He must have proved himself [and] demonstrated his God-given charisma for leadership, before he looks to the Church for recognition of it through ordination. Here once again we stand in marked contrast to the New Testament... The early Christians laid great stress on quality of life. A leader must merit respect, with his sexual, drinking [and] financial habits beyond reproach, a man of experience, a family man, someone who has led others to the faith and built Christians up in it. We go, on the whole, for untried men whose degree matters more than their lives, and who may never have led anyone to belief in Christ, or may even regard the whole idea as distasteful.
