Sacred Apostles

Sacred Apostles are members of Vatican that consist of highly trained exorcists that operate outside of the normal church jurisdiction. In the past, they were the main commanders and leaders of the heaven faction. However, in modern days, they have slowly faded into ambiguity and the common consensus is that they don't exist anymore.

Summary
The Sacred Apostles originally function as leaders of the church, so that even the lowest ranking member was at least a priest at minimum. In the current times, they function as the "dark side" of the church, doing such jobs as eliminating devil worshipers much like how Freed Sellzen did during his time as a "stray-exorcist". Because doing such actions in public can bring a bad image to the group overall, they are kept hidden and are more like a secret assassination-type group under the leader of the church.

The group is partly introduced in chapter one due to the introduction of one of it's low-ranking members, called Aleksandor Quarta, who is the brother of Xenovia Quarta; a famed exorcist in her own right.

Usually, the group's individual's never reach the higher half of the double-digits numbers, and thus, only a selective few are allowed within the ranks of the group. All former Sacred Apostles hold either high ranks in the Church or live luxurious lives away from battle. One example of a former Apostle would be The Church’s Device of Violence; Vasco Strada

They are led by the top ten highest ranking Sacred Apostles, which are called the Ten Divine Apostles.

Strength
The Sacred Apostles are a fairly powerful group of individuals. Nearly all of them are expert weapon masters in their own right and are able to use Holy Aura to the level of a mid-class devil despite being human.

Of course, each of the Sacred Apostles have their individual nuances, but a high-level mid-ranked member like Aleksandor Quarta was able to defeat fifty-two stray devils, with four of them possessing low high-class devil tier strength in one night. However, this feat may be an outlier as Aleksandor Quarta was trained by Vasco Strada himself.

All of the known Sacred Apostles are rated to be at least S-Class by the Underworld.

Ten Divine Apostles
The ten mysterious Sacred Apostles of the organization. They are dressed in a single white coloured leather hooded coat; but previously, they wore a black version of this dress during the Great War. Typically, they can be found in Vatican City in their "office" which is a single white room with ten chairs that extend upwards to a ridiculous degree.

All of them are addressed by numbers. The leader of the group is called "First" and it goes downwards from there, with the lowest ranking member called "Tenth".
