This is a strange state of things, but, fortunately, the Church comes partly to the rescue. It demands first that the maiden shall be at least fifteen years old (a point sometimes waived), that she shall not be too closely related to the man, and that she shall give her "free consent" (another matter not always investigated). The question of the "forbidden degrees" is, however, a bar to many projected alliances. The Church endeavored formerly to forbid the marriage of cousins up to the seventh degree, but that rule had proved unworkable, since god-parents were reckoned the same as relatives. The Lateran Council of 1215 has therefore ordained invalid marriages between cousins through the _fourth_ degree; and the saints know that this rule makes complications enough, considering how the great families are interrelated! Of course, the regulations are wise, otherwise heiresses would always be given in an outrageous manner to near kinsmen. On the other hand, the forbidden degrees are sometimes a little trenched upon to give the contracting parties an excuse for repudiating each other in case they get tired of their bargain--although here again is a practice which the Church treats with just anger.[27] The Church does not formally permit divorce, but it cannot thwart many of the currents of the age. Nobles frequently repudiate their wives for trivial reasons--mere ill health, for instance; and often the women take the initiative. There are worldly bishops who will give their help toward an annulment on grounds of "lack of inward consent." Again, if a very desirable marriage with a cousin comes in question, often a "dispensation" can be obtained from the same complaisant authorities. It is easy to become cynical if you study how easily the "holy bonds of matrimony" can be put on and off by the powerful, although sometimes a great pope like Innocent III will teach even a mighty king a lesson, as Philip Augustus learned when he tried to repudiate poor Ingeborg of Denmark.
