Matrimony is the marriage contract between Christians raised by Christ to the dignity of a sacrament. The theological and dogmatic treatment of this sacrament does not look very much to its main features of unity and indissolubility which are basic characteristics of all marriage in natural ethics; they are rather premisses, though of course they attain greater significance and depth and stability in marriage as a sacrament. The fact, then, that these features take up a considerable amount of space in Church documents must not be allowed to hid the theological content of this sacrament which comes to us from revelation and belongs to the supernatural order. As a sacrament matrimony is entirely oriented on man's supernatural goal. Matrimony and Holy Orders are the two sacraments which not only serve the individual in reaching this goal but are there for the benefit of the community. Matrimony is there for the mutual help of the spouses and the increase of the people of God. Devotion to his twofold end is the way of salvation for married couples, a way sanctified by the sacrament. 'Yet she shall be saved through childbearing; if she continue in faith, and love, and sanctification, with sobriety' (1 Tim:2:15).
