36. People who have separated faith from love do not even know what faith is. When they do entertain an idea about faith, some of them see it only as mere thought, others as thought directed towards the Lord, and a few as the doctrine of faith. But faith involves not only knowledge of all the things that the doctrine of faith embraces and the acknowledgment of them; it is first and foremost obedience to everything that doctrine teaches. The primary point that it teaches for men's obedience is love of the Lord and love of the neighbour. Whoever is devoid of this is devoid of faith, a point which the Lord teaches so plainly in Mark as to leave absolutely no room for doubt,

The first of all the commandments is, Hear, O Israel, the Lord our God is one Lord. Therefore you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength. This is the first commandment. The second is also like it, You shall love your neighbour as yourself. There is no other commandment greater than these. Mark 11:28-33.

In Matthew, He calls the former 'the first and great commandment', and says 'on these commandments the Law and Prophets depend', Matthew 22:35-40. The Law and the Prophets are the doctrine of faith in its entirety and the whole of the Word.

777. And upon his horns ten diadems. That this signifies that power from the appearances of truth in abundance, is evident from the signification of horns, as denoting power, of which we have just above treated; and from the signification of ten, as denoting much, thus also abundance; concerning which see above (n. 675); and from the signification of diadems, as denoting truths in the last degree of order, which are the truths of the sense of the letter of the Word; concerning which also see above (n. 717). They also denote the appearances of truth, because the truths of the letter of the Word are, for the most part, appearances of truth; and the power of those who are meant by the beast is therefrom. These are they who, by reasonings, confirm the separation of faith from life. For the truths of the letter of the Word - which are appearances of truth, which they also connect by reasonings so as to appear like genuine truths - are what are here signified by diadems. But when those truths are connected together by reasonings from falsities and fallacies, they are no longer truths in appearance, but truths falsified, and thus falsities; according to what was shown above (n. 719), and illustrated by the apparent progression of the sun.

The reason why upon the heads of the dragon there appeared seven diadems, but upon the horns of the beast ten diadems is, that by the head of the dragon is signified a knowledge of the holy things of the Word, which are falsified and adulterated, thus truths in appearance, which are the truths of the letter of the Word; but by the horns are signified their great power when the same are connected together and confirmed by reasonings from the natural man. This great power, however, is not from reasonings, but by means of reasonings from the truths of the letter of the Word.
