251. The reason why the “serpent” means all evil in general, and specifically the love of self, is that all evil has had its rise from that sensuous part of the mind, and also from that memory-knowledge [scientifico], which at first were signified by the “serpent;” and therefore it here denotes evil of every kind, and specifically the love of self, or hatred against the neighbor and the Lord, which is the same thing. As this evil or hatred was various, consisting of numerous genera and still more numerous species, it is described in the Word by various kinds of serpents, as “snakes” “cockatrices” “asps” “adders” “fiery serpents” “serpents that fly” and “that creep” and “vipers” according to the differences of the poison, which is hatred. Thus we read in Isaiah:

Rejoice not thou, whole Philistia, because the rod which smiteth thee is broken, for out of the serpent’s root shall go forth a cockatrice, and his fruit shall be a flying fire-serpent (Isaiah 14:29).The “serpent’s root” denotes that part of the mind, or that principle, which is connected with the senses and with memory-knowledge [est sensuale et scientificum]; the “cockatrice” denotes evil originating in the falsity thence derived; and the “flying fire-serpent” the cupidity that comes from the love of self. By the same Prophet also similar things are elsewhere thus described:

They hatch cockatrice’s eggs, and weave the spider’s web; he that eateth of their eggs dieth, and when it is crushed there cometh out a viper (Isaiah 59:5).

The serpent described here in Genesis is called in the Revelation the “great and red dragon” and the “old serpent” and also the “devil and satan” that “deceives the whole world” (Revelation 12:3, 9; 20:2), where, and also in other places, by the “devil” is not meant any particular devil who is prince over the others, but the whole crew of evil spirits, and evil itself.

209. For thou hast some power, and hast kept My word, and hast not denied My name, signifies that they have power from the Lord against evils and falsities, in the measure in which they make truths from the Word to be of the life, and acknowledge the Divine of the Lord in His Human. This is evident from the signification of "having power," as being power from the Lord against evils and falsities; and as those who are in faith from charity are treated of, it is said that they "have some power" (of which presently). It is evident also from the signification of "to keep My word," as being to make truths from the Word to be of the life; for to keep truths or commandments means not only to know and perceive them but also to will and do them, that is to keep them; and those who will and do, make the truths that they know and perceive from the Word to be of their life (See also above n. 15). It is evident also from the signification of "not denying My name," as being to acknowledge the Divine of the Lord in His Human (See above, n. 135).

[2] It should be known that there are two principal things of the church, namely, the acknowledgment of the Lord's Divine in His Human, and making the truths from the Word to be of one's life; moreover, no one can be in the one of these unless he is at the same time in the other; for all truths that are made to be of the life are from the Lord, and this is done with those who acknowledge the Divine in His Human. For the Lord flows in with all, as well in the heavens as on the earth, from His Divine Human, and not from the Divine separately. Consequently those who in their thought separate the Divine of the Lord from His Human, and look to the Divine of the Father not as in the Human but as beside it or above it, thus separated from it, receive no influx from the Lord nor thus from heaven, for all who are in the heavens acknowledge the Lord's Divine Human (See concerning this in the work on Heaven and Hell 2-12, 59-72, 78-86. From this it is clear that all truths that are made of the life are from the Lord with those who acknowledge the Divine in His Human, that is the Divine Human. Truths become of the life when man loves them, thus when he wills them and does them, for he who loves, wills and does; in a word, truths are made of the life when man from affection lives according to them. Such truths are from the Lord because the Lord flows into the love with man, and through the love into truths and thus makes them to be of the life.

[3] Something shall now be said about the power that man has from the Lord against evils and falsities. All power that angels have and also that men have is from the Lord; and the measure in which they receive the Lord is the measure of their power. He who believes that any power against evils and falsities comes from what is man's own [proprium] is greatly mistaken; for it is evil spirits, conjoined to the hells, that induce evils and falsities thence with men, and these spirits are numerous, and each one of them is conjoined to many hells, in each of which also there are many spirits, and no one except the Lord can turn these away from man, for the Lord alone has power over the hells, and man has no power at all from himself or from what is his own [proprium]; therefore man has power to the extent that he is conjoined to the Lord by love. There are two loves that reign in the heavens and constitute the heavens, namely, love to the Lord and love towards the neighbor; love to the Lord is called celestial love, and love toward the neighbor is called spiritual love. Those who are in celestial love have much power, but those who are in spiritual love have some power; and because what is written to the angel of this church, treats of those who are in love towards the neighbor, or in charity and in faith therefrom, which love is spiritual love, it is said, "Thou hast some power."

[4] But it is to be noted, that all the power that angels and men have from the Lord is from the good of love; and since the good of love does not act from itself but through truths, therefore all power is from the good of love through truths, and with those who are spiritual, from the good of charity through the truths of faith. For good takes on a quality through truths, good without truths having no quality and where there is no quality there is neither force nor power. From this it is clear, that good has all power through truths, or charity through faith, and neither charity apart from faith nor faith apart from charity has any power. This is meant also by the keys given to Peter, for "Peter" there means, in the spiritual sense, truth from good which is from the Lord, thus faith from charity; and the "keys" given to him the power over evil and falsities. These things were said to Peter when he acknowledged the Divine of the Lord in His Human; which means, that those have power who acknowledge the Divine of the Lord in His Human, and from Him are in the good of charity, and in the truths of faith. That these things were said to Peter when he acknowledged the Lord is shown in Matthew:

Jesus said to the disciples, Who say ye that I am? Simon Peter answered and said, Thou art the Christ, the Son of the living God. And Jesus answering said unto him, Blessed art thou Simon Bar-Jonah; for flesh and blood hath not revealed this unto thee, but My Father who is in the heavens. But I also say unto thee, thou art Peter, and upon this rock I will build My church; and the gates of the hells shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven (Matthew 16:15-19).

(But of Peter and his keys, see what is said above, n. 9; also what is shown in The small work on The Last Judgment 57, and in The Doctrine of the New Jerusalem 122; and that truth has all power from good, which is from the Lord, in the work on Heaven and Hell 228-233, 539, and Arcana Coelestia 3091, 3387, 3563, 4592, 4933, 6344, 6423, 7518, 7673, 8281, 8304, 9133, 9327, 9410, 10019, 10182).
