(b) Affirmative Precepts.—The positive modes of observing temperance (i.e., rules on fasting) are not prescribed in the Decalogue. For the law confines itself to general principles that, are of universal application, whereas the manner of practising fasts and abstinences has to be suited to conditions of time and place. Hence, it pertains to the Church to settle by her legislation the details of mortification in eating and drinking, so that they may be suited to the ever-changing conditions of human life (2469).
Question III
THE DUTIES OF PARTICULAR CLASSES OF MEN
2573. The theological and moral virtues treated in the previous Question are obligatory upon all states and conditions, for all men have the same supernatural destiny, and all alike are bound to govern their acts and their passions by the rule of reason. But not all have the same calling or office, or consequently the same particular ends to be striven for or the same special means to be used; wherefore, there are moral duties proper to particular classes and particular ways of life. Those special obligations, however, do not constitute new virtues, but are applications of the seven general virtues to the states of man diversified in reference to the acts and habits of the soul. The diversities now spoken of may be reduced to the three mentioned by St. Paul (I Cor., xii. 4 sqq.), namely, diversities of graces (i.e., some are gifted to edify the Church in marvellous ways by knowledge, speech or miracles), diversities of operations (i.e., some are called to the life of contemplation, others to active life), and diversities of ministries (i.e., there are various stations, ranks, occupations, both in ecclesiastical and non-ecclesiastical life). The higher graces and ways of the spiritual life of man are treated in works of ascetical and mystical theology, and we shall confine ourselves here to two subjects: (a) the duties of men as members of the Church, that is, the general duties of the faithful and the special duties of clerics and religious; (b) the duties of men as members of domestic and civil society.
Before proceeding any further, a word is in order regarding the role of the laity in the Church.
“We desire that all who claim the Church as their mother should seriously consider that not only the sacred ministers and those who have consecrated themselves to God in religious life, but the other members as well of the Mystical Body of Jesus Christ, have the obligation of working hard and constantly for the upbuilding and increase of this Body” (Pius XII, _Mystici Corporis_).
The Catholic layman, long a silent partner in the Church’s apostolate, has assumed a more active part in recent years. His role, his apostolate, his milieu, his special claims to divine graces, his spiritual prerogatives—all have been made subjects of theological investigation particularly by European writers. Controversy, uncertainty, at times even error have characterized their efforts as they grope their way in a new area of theology. Their efforts ultimately will lead to the elaboration of a developed theology of the laity, an extremely important and equally necessary body of knowledge, for “the laity are in the front line of the Church’s life; through them the Church is the vital principle of human society. Accordingly they especially must have an ever clearer consciousness not only of belonging to the Church, but of being the Church....” (Pius XII, _Allocution to the Sacred College, AAS_, 38-149).[1]

Art. 1: THE DUTIES OF MEMBERS OF THE CHURCH
2574. The General Duties of the Faithful.—The Church has the power to make laws which will promote the common good of the whole body and the individual good of the members (see 418). Chief among the laws that bind the faithful in general are the six known as the Precepts of the Church, namely, the laws on the observance of Sundays and holydays, on fasting and abstinence, on yearly confession, on Easter Communion, on the support of pastors, and on marriage.
