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.

2551. 'What did you see, that you have done this thing?' means a looking into the cause. This is evident without explanation, as well as from what follows where the cause is stated. The reason ideas of how the Lord perceived and thought regarding the doctrine of faith, and regarding the rational, whether it should be consulted, are presented in that particular order in the internal sense is that it is angel-like to think about them in such a sequence. The internal sense of the Word exists in particular for angels, and has accordingly been rendered suitable to their perceptions and thoughts. For them these are experiences of delight, indeed of bliss and of happiness, when they are thinking about the Lord, about His Divinity and His Humanity, and about how the latter was made Divine. For when thinking about these they are encompassed by a celestial and spiritual sphere which is filled with the Lord, so that it may be said of them that they are in the Lord. Consequently nothing is more blissful and happy for them than to think in accordance with those things which belong to that sphere and to the affection resulting from this. What is more, they are at the same time instructed and perfected, in particular in the matter of how as He grew up the Lord by degrees and from His own power made Divine the human into which He had been born, and thus how, by means of knowledge and cognitions which He revealed to Himself, He perfected His rational, gradually dispelled its shadows, and brought it into Divine light. When the Word is being read, these and countless other realities are presented to angels in a celestial and spiritual fashion, together with thousands and thousands of representatives in the light of life. But these matters which to angels are so precious are to men of little importance since they are above and beyond them and so are lost in the darkened parts of their understanding. Conversely those which are precious to men, such as hold worldly matters within them, are to angels of little importance since they are beneath their state of existence and so are lost in the darkened parts of their wisdom. Thus, wondrous to tell, the very things which enter the darkened parts of man's mind, and almost into his contempt, pass into the light angels enjoy and into their affection, as do many things which belong to the internal sense of the Word.
