Every individual member of the community should have this living faith and should exercise this confessorship. It will be exercised in infinitely various ways according to each one’s particular qualities, according to his bent of mind, the graces he receives, his special vocation, his environment and fortunes. For the one revealed truth may be expressed and applied in an infinite variety of ways. And every one of these various expressions reveals new vistas of its hidden beauty and power, displays new types of the Christian ideal and sets before us new incentives to imitation. The characteristic types of the Christian life—confessor, martyr, prophet, hermit, monk, virgin, widow— change into ever new forms, and each new form contains a creative tendency to further forms, until the whole content of the Christian life is exhausted. The most fundamental, the simplest, and the most effective form in which living faith becomes inspiring testimony will certainly always be found in the Christian family. The family reflects, as no other social institution does, the mystery of the Church, her real union with Christ, her Head (Eph. v, 32). The family illustrates, as it is illustrated nowhere else, the priesthood of the laity and shows it in all its beauty. For bride and bridegroom, in virtue of their priestly character, are themselves the ministers of the sacrament of their union, and, entering upon the life so consecrated, propagate in their children and children’s children their own devout faith. The Christian family is the nucleus of the lay apostolate, of that faith which awakens and enkindles faith, which continually flames up anew and through whole generations gives testimony to Christ.
