Apocalypse Explained#142
142. (Verse 15) So hast thou also them that hold the doctrine of the Nicolaitanes, which thing I hate. That this signifies those who separate good from truth, or charity from faith, which is contrary to Divine order, is evident from what was said and shown above, n. 107, where similar words occur. To which must be added, that those who separate truth from good, or faith from charity, turn away from themselves all influx of heaven into the good works which they do, in consequence of which their good works are not good; for heaven flows in, that is the Lord, through heaven, into the good of man's love, therefore he who casts out the good of charity from the doctrine of the church, and instead of it receives only those things which are said to belong to faith, is excluded from heaven, the truths pertaining to him not having life. And it is the life of truth, which is good, that conjoins, but not truth without life, or faith without charity. (But more may be seen concerning these things in The Doctrine of the New Jerusalem, where it treats concerning charity, n. 84-107, and concerning faith, n. 108-122.)

84. Love for Our Neighbor, or Caring
First of all, I need to define neighbor, because this is the one we are to love and the one toward whom caring is to be extended. Unless we know what neighbor means, we may extend caring in basically the same manner indiscriminately-just as much to evil people as to good ones. But in that case our caring can become the opposite of caring, because although the good people will use what they have been given to do good to their neighbor, the evil people will use it to do harm.
