The Church has the authority over marriage (Council of Trent , sess. 24, can. 4 ), and Canon Law has established the diriment impediment : >Can. 1083 §1. A man before he has completed his sixteenth year of age and a woman before she has completed her fourteenth year of age cannot enter into a valid marriage. But can, in addition to this, the Church say that the difference in ages between the man and woman marrying must not be more than, for example, 10 years? Have canonists deliberated on the question of marital age disparity? Is there a reason the Church does not (at least currently) have a law prohibiting marriages with large age disparities?
