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.

286. Lord God Almighty, who was, and who is, and who is to come. That this signifies who is the Infinite and the Eternal is evident from the signification of Almighty, as denoting that He is the Infinite, of which we shall speak presently, and from the signification of, who was, who is, and who is to come, as denoting that He is the Eternal (concerning which see above, n. 23). There are two things which can be predicated of Jehovah alone, that is, of the Lord - infinite and eternal; infinite, of His Being (esse), which is the Divine good of His Divine love; eternal, of His manifestation (existere) from that Being (esse), which is the Divine truth of His Divine wisdom. These two are Divine in themselves. From these the universe was created; therefore also all things in the universe have reference to good and truth, and good is everywhere the being (esse) of a thing, and truth is the manifestation (existere) therefrom; but these two in all things of the universe are finite. This is why it is here said "Lord God"; for Lord signifies the Divine good of the Divine love, and God the Divine truth of the Divine wisdom. (That Jehovah in the Word is called Lord from Divine good, may be seen, Arcana Coelestia 4973, 9167, 9194; and that He is called God from Divine truth, n. 2586, 2769, 2807, 2822, 3921, 4287, 4402, 7010, 9167). From these considerations it is clear that Almighty signifies the Infinite, and that who was, who is, and who is to come signifies the Eternal.
