5 It may be said that today ecclesiastical celibacy has been examined more penetratingly than ever before and in all its aspects. It has been examined from the doctrinal, historical, sociological, psychological and pastoral point of view. The intentions prompting this examination have frequently been basically correct although reports may sometimes have distorted them. Let us look openly at the principal objections against the law that links ecclesiastical celibacy with the priesthood. The first seems to come from the most authoritative source, the New Testament which preserves the teaching of Christ and the Apostles. It does not openly demand celibacy of sacred ministers but proposes it rather as a free act of obedience to a special vocation or to a special spiritual gift.
