Two different theories of marriage were in vogue for some time in the schools of canonical jurists. For
Gratian and the school of Bologna, marriage is begun by consent, but it becomes complete, indissoluble, and a sacrament only when it is consummated. For Peter Lombard and the school of Paris, marriage contracted by mutual consent alone is a true and complete marriage, absolutely indissoluble, and, between Christians, a sacrament. This second theory had the support of early Christian writers, received the approval of Sovereign Pontiffs, particularly of Alexander III, and soon prevailed. It was conceded, however, to the first theory that, whilst non-consummated marriage is a complete marriage and a sacrament, yet it is not absolutely indissoluble. This quality belongs fully to the marriage ratified and consummated. Thus mutual consent is sufficient to constitute marriage in its essence; consummation adds an accidental perfection and more absolute indissolubility Absolute indissolubility is attributed only to ratified and consummated marriages between Christians.
1917 Code of Canon Law Canon 1119 of the
1917 Code of Canon Law stipulated two cases in which a marriage
ratum sed non consummatum may be dissolved, namely, (1) if one of the parties takes solemn vows in a religious order or (2) a dispensation is issued by the Holy See.
Dissolution by solemn religious profession That solemn religious profession dissolves a merely ratified marriage was authoritatively declared by
Alexander III (c. 2 and 7, x, iii, 32) and
Innocent III (c. 14, x, iii, 32), universally received in practice, after them, and defined by the
Council of Trent (Sess. xxiv, De Sacramento Matrimonii, Can. 6). The only question which remained controverted was whether religious profession dissolved marriage by divine, or, as more commonly admitted, by ecclesiastical, right. ==Current discipline under the 1983 Code==
