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.

Fish represent knowledge. Fish laid upon the fire, as in John 21:9, represent the reformation of the natural man by the good of love, of which description were all the men of that time, in consequence of the complete vastation of the church. Fish signify sensual affections which are the ultimate affections of the natural man. Fish sometimes also represent people in common truth or conversely in external falsity. Broiled fish, as in Luke 24:42, signify the truth of good relating to the natural and sensual man, and honeycomb, the good of the same truth. To make as the fishes of the sea, signifies to make altogether sensual. Fish, as in Habakkuk 1:14-16, signify people in faith separate from charity.
