Seven Deadly Sins

The Seven Deadly Sins (七つの大罪) is a concept in Christianity that refers to sins that are worse to commit than others, in that they, if succumbed to, can lead one directly to sin even more. These sins are lust (色欲), gluttony (暴食), greed (強欲), sloth (怠惰), wrath (憤怒), envy (嫉妬), and pride (傲慢).

Following this concept is a magic spell the Russian Orthodox Church uses to target Kamijou Touma and Othinus.

Spell
During the manhunt for Othinus and Kamijou Touma, the Russian Orthodox Church headed by Patriarch Krans R. Tsarskiy had constructed a unique spell to use against Othinus, which made use of the concept of the Seven Deadly Sins. It can be called the Russian Orthodox Church's secret spell, requiring funding and preparations on a national level. Before using, a Russian Orthodox believer is within a certain range of the target, the target includes anyone that the Patriarch has deemed an enemy. The Patriarch needs to know the target, however, through the use of a name, a photo, and some way of sensing the target with one of his five senses. When Krans confronted Touma, he communicated with him using a phone, allowing him to hear Touma.

The spell's origins can be traced to Christianity in bringing different belief systems and gods to fit into their own belief system, like gods of Celtic and Norse religions turning into demons, and their heroes turned into their Saints. The spell brings other gods (in this case, the target) into the system of the Russian Orthodox Church and then reevaluates them by judging them according to its rules. By the way Krans have worded, it is implied that there is more to the spell than just the Seven Deadly Sins. This likely refers to other rules that are present in the Russian Orthodox Church that can be used in place of the concept of the Seven Deadly Sins. Using this concept, the spell allows the Patriarch to remove the power of the target has improperly obtained, which is based on the sins he believes can apply on the target. For each sin that he applies, 1/7 of that power is removed from the target. When talking about "power" being removed it is shown to be the control and movement over the muscles. Indeed, Krans has stated that once all seven sins are gathered, the target will lose even the strength needed to move the muscles of the heart. The spell works based on the judgment that is made by the user by finding fault in other religions (belief systems) and strip them of their power. It doesn't matter if the user is right or not in their judgment, as the spell takes the user's one-sided complaints and transforms them into real attacks.

However, when a target is judged to have a sin, and if that target truly doesn't believe that sin applies to them or if the sin truly is inapplicable to the target, they are apparently unaffected by the effects of the spell during that judgment. This is also compounded by the user's confidence in applying the sin on the target. Another weakness of this spell that it doesn't have a "breaker" like the ones used by the Roman Catholic Church for their spells such as the Fish of the Supper, a core that controls the spell. Because of this, the spell can backfire on the user, though it is only shown when the concept of Seven Deadly Sins is used. Here, the target can apply the same judgment on the user, as exemplified by Touma judging Krans with sin after sin, apparently making him faint. Moreover, due to the fact that a believer of Russian Orthodox Church is required for the scope of the spell, any believer will be unable to interfere or bring harm to the target when they have reversed the spell on the user lest they affect the user with the spell as well, which in this case is the Patriarch. Indeed, when Touma begins reversing the spell on Krans, Vasilisa and Sasha Kreutzev are only forced to watch as cutting Touma's words with violence can be viewed as being prideful as well.

The spell is apparently active for only a certain amount of time, or can be apparently deactivated. During this period, after a target has successfully reversed the spell, the user is in danger if any believer of the Russian Orthodox Church is to bring harm on the target.

Background
The spell was constructed at some point during the preparations for the battle against Othinus by the Russian Orthodox Church, to be used against Othinus herself.

Magic God Othinus Arc
During the manhunt for Othinus and Kamijou Touma, when Vasilisa and Sasha Kreutzev confronted Touma, Krans R. Tsarskiy communicated with him over a military radio and used the Seven Deadly Sins spell to incapacitate him. However Touma managed to figure out the mechanics of the spells and turned it against the Patriarch.

Trivia

 * Interestingly, Orthodox Christianity actually adds an eighth sin: Despair. As a result, there are often references made to "succumbing to the eighth deadly sin" in classic Russian literature.
