I don't know about accursed, but ive recently fallen into a fascination with Belial.
According to the key of Solomon Belial is summoned to grant offices and gain favor with friends and foes. They appears as two beautiful angels in a flaming chariot, and proudly declares they were the second to fall after Lucifer. Other texts place them as the ruler of the second dark world. They are a well known deceiver, double timing two faced, which reinforced my perception of their affinity with the number 2.
While some speculate that Belial is a god form from Babylon, given that Bel= Lord and Al=god; and while not mutually exclusive, it is certainly the case that when used in the bible the name comes from the is derived from the Hebrew word for worthless or useless. I's sometimes debate weather Belial is a proper name for a daemon at all be cause of this. Most instances of its usage are in relation to the sons or daughters of Belial, or the useless sons and daughters. though 2 Corinthians 6:14-15 does place Belial in direct opposition to Christ.
14 Do not be yoked with unbelievers. For what do righteousness and wicked ness have in common? Or what fellow ship can light have with darkness?
15 what harmony is there between Christ and Belial? What harmony is there between a believer and an unbeliever
There are some extraneous texts to the bible that seem to support this conclusion. The Testament of the 12 Patriarchs, for example, again places Belial in direct opposition to god as a tempter, and the Ascension of Isiah places them as a lawless ruler of the Earthly world. Similarly the _Dead Sea Scrolls_ depict Belial as the Leader of the Army of Darkness in the cosmic war against the light. The Testament of Arman reconfirms this by placing Belial in opposition to the Michael in the war. IT also grants him the titles of "Price of Darkness" and "King of Evil", titles later falsely granted to Lucifer. Belial is constantly placed with the most powerful of demons, alongside Lucifer, Leviathan, Satan, Asmoday and Bileth. The Pseudomonarchia Daemonum credits them with being the seducer of all other angels that fell. A fitting accusal for the deity supposedly worshipped at Soddam and Gammorah. There are also those that claim Belial (Bel-Al) as the Dark personification of Ein Soph.
This last one is of significant personal interest to me. I have been thinking of the initial catastrophe and the fall from the garden. Originally Adam Kaddamon was created to distribute divine light down through the Tree of Life, but when the top three sephirot captured the light they were shattered and 288 divine sparks dropped into the abyss in which Lucifer fell. Later, when the fruit of knowledge is consumed, the garden that was previously defined by a stagnant static unity beyond borders is infected by death. Adam Kaddamon falls and becomes Adam Belliayyal, the useless, subject to all constrictions of the material realm of Malkuth. Adam and Eve become cursed by god to be slaves to utility, forced to toil the earth for their bread.
Kaddamon being Belial would place them in them in the proper order to be the second fallen and from a height even above that of Lucifer, additionally explaining the pride in the declaration of being second (though why ought we give primacy to one anyway?). They're in an order to be the seducer of the other angels as well, agreeing well with their reputation of deception. It places them in a proper role of opposition to Michael, the yellow sun, being the former distributor of the divine cosmic light itself now fallen into darkness. As a rebellion against God and Christ, being a deity of uselessness they fight against the condition of imposed utility. A condition which the pursuit of knowledge is able to offset by freeing excess beyond that which must be maintained for the continuation of base life. Interestingly when Da'ath falls from the tree into the abyss the perfect state of knowledge becomes altered. It is now accompanied in a state of desire, of pursuit, where it is acquired to change oneself and the environment. When Adam and Eve eat the fruit of knowledge they become like gods, able to create, as death, change, enters the garden. It is then easy enough to surmise that the divine sparks that fell into the abyss were death, which allows for the change in the state of knowledge. Destruction which is required for creation. Temptation for which is carried by the serpent into the garden. Some Gnostic sects claim the serpent as the savior, bringing knowledge and creation to human kind, and freeing them of the stagnant state to which they had been placed by god. Is is simply then common sense to see Belial as the origin of this salvation through change, through chance, as the origin of the sparks, and the punishment they received.
