On the other hand, the alternate opinion has solid grounds and arguments, and merits due consideration. Some authors distinguish a twofold law of Christ; (a) absolute, that which obliges immediately and of itself independently of any action of man; e.g., the law concerning the necessity of Baptism or determining bread and wine as the matter of the Eucharist; (b) hypothetic, which presupposes some human action; e.g., the law of the indissolubility of matrimony which urges after man has freely willed to be bound by the laws of matrimony. Similarly, the binding force of vows presupposes the taking of the vow. As to the absolute law, no human authority may dispense from it. As already indicated, the good of the Church, its unity and stability, seem to demand an unchangeable law. In regard to the hypothetical law, many of the more modern authors assert that the Holy Pontiff can at times dispense. The power of loosing implies a power of dispensing in the Church which has been used in particular cases; e.g., _ratum et non consummatum_ matrimony. Moreover, the power to dispense seems extremely useful and almost necessary for the prudent and wise governing of the Church. For, with a change of circumstances an individual might be impeded from doing a greater good because of a preceding act of will; e.g., one might be impeded from embracing the religious life because of a prior vow to remain in the world to assist in Catholic Action (see Fanfani, O.P., _Theol. Moral. Manuale_, Vol. I, n. 134). 358. Interpretation of the Law of Christ.-(a) Private interpretation (_epieikeia_ or equity) is used in extraordinary cases, not foreseen by the lawgiver, and it declares that a particular case does not fall under the Law. This kind of interpretation applies only to human laws, since God foresees things not only universally, but also in particular (cfr. on Natural Law, 315). (b) Public interpretation of the Law of Christ is made by the Church, in virtue of the commission: “Teach all things whatsoever I have commanded” (Matt, xxviii. 20). 359. Public Interpretation of the Law of Christ--(a) The Church is able to give a declarative interpretation of the Positive Divine Law--that is, to explain its meaning, to show what cases are comprehended in the law, what cases are not, when one is obliged, when one is excused, etc. Example: The Church interprets the doctrine of Christ on the indissolubility of marriage, explaining when the bond is absolutely indissoluble, the conditions under which it may sometimes be dissolved, etc.
