Holy magic 「神聖魔法, shinsei mahō」 is a type of elemental magic, requiring a contract with a holy spirit or a god. For the purposes of holy magic, any being capable of manipulating spiritrons is sufficient as a god.[1] Despite being a form of elemental magic, it is considered one of the four main magic types.
Principles[]
For a person to use holy magic, they need to form a "pact" with a god or be a god themselves. The condition to learn holy magic as a believer is simply a heart that believes in miracles. The power of faith 「信仰の力, shinkō no chikara」 turns their strong thoughts or feelings into power, making it accessible to even monsters and daemons. Once a pact is created between the god and believer, the believer uses their god's "name" as a medium to open a soul-based channel between the two, offering mana in exchange for the god's assistance.
On the god's end, since there's no way to assist many people at once, they link together and borrow the cumulative computational power of their believers to share the burden of putting the magic together. Since the burden placed on the user is low, the resulting holy magic's strength depends almost entirely on how much "faith" the user has in their respective god. The stronger the believer's "faith" is, the stronger the connection between the two is, and as a result, the stronger the magic becomes.

This system as a whole is collectively referred to as the Secret of Faith and Grace 「信仰と恩寵の秘奥, shinkō to onchō no hiō」.
Types[]
Holy magic can be split into two distinct categories based on the type of power being borrowed from/used by the respective god.
Basic-level[]
Basic holy magic spells make use of holy power that can purify magicules and heal wounds. While its offensive options are minimal and don't work very well against regular beings, against monsters and especially undead, they're almost always a sure-fire kill.

Recovery
- Healing 「体力回復, hīringu」: A healing magic that restores the target's stamina and lost blood.
- Holy Bell 「聖なる福音, hōrī beru」: A wave of holy power surges outwards from the user in all directions, purifying a large amount of magicules and destroying monsters while the sound of a bell sings their requiem. This magic is traditionally used to purify Undead.
- Holy Cannon 「霊子聖砲, hōrī kanon」
- Holy Field 「聖浄化結界, hōrī fīrudo」
- Alignment Field 「対魔属性結界, araimento fīrudo」
- Prison Field 「四方印封魔結界, purizun fīrudo」
- Recovery 「傷病治癒, rikabarī」: A healing magic that closes wounds and reattaches severed limbs. However, it cannot restore the target's stamina or blood supply.
- Turn Undead 「死者浄化, tān andeddo」
Miracles[]
Miracles of God 「神の奇跡, kami no kiseki」 make use of a god's power to manipulate spiritrons. The magic belonging to this category is immensely powerful and the offensive spells it offers are highly effective on all targets, not just monsters. Even an ultimate skill user with their immunity to lesser forms of magic will find themselves in danger against the power of miracles.

Trivia[]
- Since holy magic is usually associated with the Western Holy Church and monster slaying, it is widely believed in-universe that monsters are not capable of using holy magic. Therefore, most characters react in shock after seeing a monster cast it.
- In Luminism, being able to use "Miracles" is required to advance to the rank of Bishop.
- In Seven Deadly Sins Grand Cross [Oni Princess] Shuna uses Holy Bell as a healing move and with a Holy Relic she can cleanse one debuff excluding Death Matches.
