"What doth it profit, my brethren, if a man believe he hath faith, but hath not works? can that faith save him? If a brother or sister be naked and in lack of daily food, and one of you say unto them, Go in peace, be ye warmed and filled; and yet ye give them not the things needful to the body; what doth it profit? Even so faith, if it have not works, is dead in itself. But some one will say, Thou hast faith, and I have works: Shew me thy faith which is without works, and I, by my works, will show thee my faith. Thou believest there is one God; thou doest well: the demons also believe, and tremble. But wilt thou know, O vain man, that faith without works is dead? Was not Abraham our father justified by works when he offered up Isaac his son upon the altar? Thou seest that faith wrought with his works, and by works was faith made perfect.... Ye see that by works a man is justified, and not only by faith.... For as the body without the spirit is dead, so faith is dead without works." (James ii. 14-26.)
James says that the indication of faith is the acts that it inspires, and consequently that a faith which does not result in acts is of words merely, with which one cannot feed the hungry, or justify belief, or obtain salvation. A faith without acts is not faith. It is only a disposition to believe in something, a vain affirmation of belief in something in which one does not really believe. Faith, as the apostle James defines it, is the motive power of actions, and actions are a manifestation of faith.
The Jews said to Jesus: "What signs shewest thou then, that we may see, and believe thee? what dost thou work?" (John vi. 30. See also Mark xv. 32; Matt. xxvii. 42). Jesus told them that their desire was vain, and that they could not be made to believe what they did not believe. "If I tell you," he said, "ye will not believe" (Luke xxii. 67); "I told you, and ye believed not.... But ye believe not because ye are not of my sheep" (John x. 25, 26).
The Jews asked exactly what is asked by Christians brought up in the Church; they asked for some outward sign which should make them believe in the doctrine of Jesus. Jesus explained that this was impossible, and he told them why it was impossible. He told them that they could not believe because they were not of his sheep; that is, they did not follow the road he had pointed out. He explained why some believed, and why others did not believe, and he told them what faith really was. He said: "How can ye believe which receive your doctrine (δόξα[19]) one of another, and seek not the doctrine that cometh only from God?" (John v. 44).
To believe, Jesus says, we must seek for the doctrine that comes from God alone.
"He that speaketh of himself seeketh (to extend) his own doctrine, δόξαν τὴν ἴδιαν, but he that seeketh (to extend) the doctrine of him that sent him, the same is true, and no untruth is in him." (John vii. 18.)
The doctrine of life, δόξα, is the foundation of faith, and actions result spontaneously from faith. But there are two doctrines of life: Jesus denies the one and affirms the other. One of these doctrines, a source of all error, consists of the idea that the personal life is one of the essential and real attributes of man. This doctrine has been followed, and is still followed, by the majority of men; it is the source of divergent beliefs and acts. The other doctrine, taught by Jesus and by all the prophets, affirms that our personal life has no meaning save through fulfilment of the will of God. If a man confess a doctrine that emphasizes his own personal life, he will consider that his personal welfare is the most important thing in the world, and he will consider riches, honors, glory, pleasure, as true sources of happiness; he will have a faith in accordance with his inclination, and his acts will always be in harmony with his faith. If a man confess a different doctrine, if he find the essence of life in fulfilment of the will of God in accordance with the example of Abraham and the teaching and example of Jesus, his faith will accord with his principles, and his acts will be conformable to his faith. And so those who believe that true happiness is to be found in the personal life can never have faith in the doctrine of Jesus. All their efforts to fix their faith upon it will be always vain. To believe in the doctrine of Jesus, they must look at life in an entirely different way. Their actions will coincide always with their faith and not with their intentions and their words.
In men who demand of Jesus that he shall work miracles we may recognize a desire to believe in his doctrine; but this desire never can be realized in life, however arduous the efforts to obtain it. In vain they pray, and observe the sacraments, and give in charity, and build churches, and convert others; they cannot follow the example of Jesus because their acts are inspired by a faith based upon an entirely different doctrine from that which they confess. They could not sacrifice an only son as Abraham was ready to do, although Abraham had no hesitation whatever as to what he should do, just as Jesus and his disciples were moved to give their lives for others, because such action alone constituted for them the true meaning of life. This incapacity to understand the substance of faith explains the strange moral state of men, who, acknowledging that they ought to live in accordance with the doctrine of Jesus, endeavor to live in opposition to this doctrine, conformably to their belief that the personal life is a sovereign good.
The basis of faith is the meaning that we derive from life, the meaning that determines whether we look upon life as important and good, or trivial and corrupt. Faith is the appreciation of good and of evil. Men with a faith based upon their own doctrines do not succeed at all in harmonizing this faith with the faith inspired by the doctrine of Jesus; and so it was with the early disciples. This misapprehension is frequently referred to in the Gospels in clear and decisive terms. Several times the disciples asked Jesus to strengthen their faith in his words (Matt. xx. 20-28; Mark x. 35-48). After the message, so terrible to every man who believes in the personal life and who seeks his happiness in the riches of this world, after the words, "How hardly shall they that have riches enter into the kingdom of God," and after words still more terrible for men who believe only in the personal life, "Sell whatsoever thou hast and give to the poor;" after these warning words Peter asked, "Behold, we have forsaken all and followed thee; what shall we have therefore?" Then James and John and, according to the Gospel of Matthew, their mother, asked him that they might be allowed to sit with him in glory. They asked Jesus to strengthen their faith with a promise of future recompense. To Peter's question Jesus replied with a parable (Matt. xx. 1-16); to James he replied that they did not know what they asked; that they asked what was impossible; that they did not understand the doctrine, which meant a renunciation of the personal life, while they demanded personal glory, a personal recompense; that they should drink the cup he drank of (that is, live as he lived), but to sit upon his right hand and upon his left was not his to give. And Jesus added that the great of this world had their profit and enjoyment of glory and personal power only in the worldly life; but that his disciples ought to know that the true meaning of human life is not in personal happiness, but in ministering to others; "the son of man came not to be ministered unto, but to minister, and to give his life a ransom for many." In reply to the unreasonable demands which revealed their slowness to understand his doctrine, Jesus did not command his disciples to have faith in his doctrine, that is, to modify the ideas inspired by their own doctrine (he knew that to be impossible), but he explained to them the meaning of that life which is the basis of true faith, that is, taught them how to discern good from evil, the important from the secondary.
To Peter's question, "What shall we receive?" Jesus replies with the parable of the laborers in the vineyard (Matt. xx. 1-16), beginning with the words "For the kingdom of heaven is like unto a man that is a householder," and by this means Jesus explains to Peter that failure to understand the doctrine is the cause of lack of faith; and that remuneration in proportion to the amount of work done is important only from the point of view of the personal life.
