Those who are in The Good of Love and of Charity
There are many who say that man is saved by faith, or, in their words, if he only has faith; but for the most part they are those who do not know what faith is. Some suppose that it is mere thought; some that it is an acknowledgment of something to be believed; some that it is the whole doctrine of faith, which is to be believed; and others otherwise. Thus in the bare knowledge of what faith is they wander in error; consequently in the knowledge of what that is by which man is saved. Faith, however, is not mere thought, nor is it an acknowledgment of something to be believed, nor a knowledge of all things which belong to the doctrine of faith. By these no one can be saved; for they can take root no deeper than in the thought, and thought saves no one, but the life which the man has procured for himself in the world by means of the knowledges of faith. This life remains; whereas all thought which does not accord with the life perishes, even so as to become none at all. The heavenly consociations are according to lives, and by no means according to thoughts which are not of the life. Thoughts which are not of the life are counterfeit, and such are altogether rejected.
In general, life is twofold, being on the one hand infernal, on the other heavenly. Infernal life is acquired from all those ends, thoughts, and works which flow from the love of self, consequently from hatred against the neighbor; heavenly life, from all those ends, thoughts, and works which are of love toward the neighbor. The latter is the life to which all things that are called faith have regard, and which is procured by all things of faith. All this shows what faith is, namely, that it is charity, for to charity all things lead which are said to be of the doctrine of faith; in it they are all contained, and from it they are all derived. The soul, after the life of the body, is such as its love is.
But as the human race began to will what is evil, to hate the neighbor, and to exercise revenges and cruelties, insomuch that that part of the mind which is called the will was altogether destroyed, men began to make a distinction between charity and faith, and to refer to faith all the doctrinal matters that were of their religion, and call them by the single term faith; and at length they went so far as to say that they could be saved by faith alone - by which they meant their doctrinal things - provided they merely believed these, no matter how they might live. Thus was charity separated from faith, which is then nothing else whatever (to speak by comparison) than a kind of light without flame, such as is wont to be the light of the sun in time of winter, which is cold and icy, insomuch that the vegetation of the earth grows torpid and dies; whereas faith from charity is like the light in the time of spring and summer, by which all things germinate and bloom.
This may also be known from the fact that love and charity are celestial flame, and that faith is the spiritual light therefrom. In this manner also do they present themselves to perception and sight in the other life; for there the Lord's celestial manifests itself before the angels by a flaming radiance like that of the sun, and the Lord's spiritual by the light from this radiance, by which also angels and spirits are affected as to their interiors, in accordance with the life of love and charity that appertains to them. This is the source in the other life of joys and happinesses with all their varieties. And all this shows how the case is with the statement that faith alone saves.
