48. BRIEF ANALYSIS.
Before this is demonstrated, we shall first explain the origin and nature of charity, and the origin and nature of faith, and thus the origin and nature of good works, which are called fruits. Faith is truth, wherefore the doctrine of faith is the doctrine of truth; and the doctrine of truth is of the understanding, and thence of the thought, and from this of the speech; wherefore it teaches what we are to will and do, thud that evils and what evils are to be shunned, and that goods and what goods are to be done. When man does goods then goods thence conjoin themselves with truths, because the will is conjoined with the understanding, for good is of the will, and truth is of the understanding; from this conjunction the affection of good exists, which in its essence is charity, and the affection of truth, which in its essence is faith, and these two united together constitute a marriage. From this marriage good works are produced, as fruits from a tree; and hence they are the fruits of good, and the fruits of truth; the latter are signified in the Word by grapes, but the former by olives.
