Introduction
(Summa Theologica, II-II, qq. 1-9.)
The order of the theological virtues here followed is that given by St. Paul in I Cor., xiii. 13—viz., faith, hope, charity. The order of these virtues is twofold: (a) according to dignity the order is charity, hope, faith; (b) according to time, the order is that of I Cor., xiii. The habits of these three virtues are infused at the same time (i.e., at the moment when grace is conferred), but their acts are not simultaneous, and one must believe before one can hope or love.
Excellence of the Virtue of Faith
Excellence of the Virtue of Faith.—(a) Faith is the beginning of the supernatural life, the foundation and the root of justification, without which it is impossible to please God and arrive at fellowship with Him. (b) It is an anticipation of the end of the supernatural life, for by faith we believe that which we shall behold in the beatific vision: “All these died according to faith, not having received the promises, but beholding them afar off, and saluting them and confessing that they are pilgrims and strangers on the earth” (Heb., xi. 13).
Utility of Faith for the Individual
Utility of Faith for the Individual.—(a) Through faith the intellect receives a new light, which discloses to it a higher world—“the wisdom of God in a mystery” (I Cor., ii. 7)—and which illuminates even this lower world with a heavenly brightness, that man may know more quickly, more surely, and more perfectly the natural truths that pertain to God and duty. (b) The will is strengthened to perform duties valiantly through the motives and examples which faith offers: the patriarchs of old “by faith conquered kingdoms, wrought justice, obtained promises, recovered strength from weakness” (Heb., xi. 33). In adversity faith is a stay and a consolation: “For what things soever were written, were written for our learning, that through patience and the comfort of the scriptures, we might have hope” (Rom., xv. 4).
Utility of Faith for Society
Utility of Faith for Society.—(a) Domestic society is defended in its security and happiness by faith, which teaches the sacramental character of marriage, which offers the model of the Holy Family to Christian homes, which never ceases to declare in the name of God the duties of husbands and wives, parents and children. (b) Without faith and religion civil society cannot be maintained in strength and prosperity. It is faith in God more than laws or armies that gives security to life, reputation, and property, with order and peace at home and abroad.
