Faith in the widest sense of the word, is assent to the truth, or the persuasion of the mind that a thing is true. In ordinary popular language we are said to believe whatever we regard as true. The primary element of faith is trust. The Hebrew word אָמַן means to sustain, to uphold. In the Niphal, to be firm, and, in a moral sense, to be trustworthy. In the Hiphil, to regard as firm, or trustworthy, to place trust or confidence in. In like manner the Greek πιστεύω (from πίστις, and that from πείθω, to persuade), means to trust, i.e., to be persuaded that a person or thing is trustworthy. Hence the epithet πιστός is applied to any one who is, and who shows himself to be, worthy of trust. In Latin credere (whence our word credit) has the same meaning. In mercantile matters it means to lend, to trust to; and then in general, to exercise trust in. “Crede mihi,” trust me, rely on my word. Fides (from fido, and that from πείθω), is also trust, confidence exercised in regard to any person or thing; then the disposition, or virtue which excites confidence; then the promise, declaration, or pledge which is the outward ground of confidence. In the cognate words, fidens, fidelis, fiducia, the same idea is prominent. The German word “Glaube” has the same general meaning. It is defined by Heinsius (Wörterbuch): “der Zustand des Gemüthes, da man eine Sache für wahr hält und sich darauf verlässt,” i.e., “that state of mind in which a man receives and relies upon a thing as true.” The English word “faith” is said to be from the Anglo-Saxon “fægan” to covenant. It is that state ef mind which a covenant requires or supposes; that is, it is confidence in a person or thing as trustworthy. “To believe,” is defined by the Latin “credere, fidem dare sive habere.” “The etymologists,” says Richardson, “do not attempt to account for this important word: it is undoubtedly formed on the Dut. Leven; Ger. Leben; A.-S. Lif-ian, Be-lif-ian; Goth. Liban, vivere, to live, or be-live, to dwell. Live or leve, be- or bi-live or leve, are used indifferently by old writers, whether to denote vivere or credere… . . To believe, then, is to live by or according to, to abide by; to guide, conduct, regulate, govern, or direct the life by; to take, accept, assume or adopt as a rule of life; and, consequently, to think, deem, or judge right; to be firmly persuaded of, to give credit to; to trust, or think trustworthy; to have or give faith or confidence; to confide, to think or deem faithful.”
The Primary Idea of Faith is Trust.
From all this it appears that the primary idea of faith is trust. The primary idea of truth is that which is trustworthy; that which sustains our expectations, which does not disappoint, because it really is what it is assumed or declared to be. It is opposed to the deceitful, the false, the unreal, the empty, and the worthless. To regard a thing as true, is to regard it as worthy of trust, as being what it purports to be. Faith, in the comprehensive and legitimate meaning of the word, therefore, is trust.
In accordance with this general idea of faith, Augustine1 says, “Credere, nihil aliud est, quam cum assensione cogitare.” Thus, also, Reid2 says, “Belief admits of all degrees, from the slightest suspicion to the fullest assurance… . . There are many operations of the mind in which … . we find belief to be an essential ingredient… . . Belief is an ingredient in consciousness, in perception, and in remembrance… . . We give the name of evidence to whatever is a ground of belief… . . What this evidence is, is more easily felt than described… . . The common occasions of life lead us to distinguish evidence into different kinds, … . such as the evidence of sense, the evidence of memory, the evidence of consciousness, the evidence of testimony, the evidence of axioms, the evidence of reasoning… . . They seem to me to agree only in this, that they are all fitted by nature to produce belief in the human mind.”
The more limited Sense of the Word.
There is, however, in most cases a great difference between the general signification of a word and its special and characteristic meaning. Although, therefore, there is an element cf belief in all our cognitions, there is an important difference between what is strictly and properly called faith, and those states or acts of the mind which we designate as sight or perception, intuition, opinions, conclusions, or apodictic judgments. What that characteristic difference is, is the point to be determined. There are modes of statement on this subject current among a certain class of philosophers and theologians, which can hardly be regarded as definitions of faith. They take the word out of its ordinary and established meaning, or arbitrarily limit it to a special sphere of our mental operations. Thus Morell3 says, “Faith is the intuition of eternal verities.” But eternal verities are not the only objects of faith; nor is intuition the only mode of apprehending truth which is of the nature of belief. The same objections bear against the assertion that “Faith is the organ for the supernatural and divine; “or, as Eschenmayer expresses it,4 “Ein vom Denken, Fühlen und Wollen verschiedenes, eigenthümliches Organ für das Ewige und Heilige; a special organ for the eternal and the holy.” The supernatural and divine, however, are not the exclusive objects even of religious faith. It is by faith we know that the worlds were made by the word of God; it was by faith Noah prepared the ark, and Abraham, being called of God, went out not knowing whither he went. The objects of faith in these cases are not what is meant by “eternal verities.” It is, moreover, an arbitrary assumption that faith is “a special organ,” even when things supernatural and divine are its object. Our nature is adapted to the reception of all kinds of truth of which we can have any idea. But it is not necessary to assume a special organ for historical truths, a special organ for scientific truths, and another for the general truths of revelation, and still another for “the eternal and the holy.” God has constituted us capable of belief, and the complex state of mind involved in the act of faith is of course different according to the nature of the truth believed, and the nature of the evidence on which our faith is founded. But this does not necessitate the assumption of a distinct organ for each kind of truth.
