Sacraments, or also known as Gospels, are the fourth sealing language of the world. This language originated on Angels, thus this is the first verbal sealing language of all.
Sacraments created and teached to the world because of Aramaic. The spells usually are kind and healing, but occult on demons. Upon later, the Grand Library accepted Sacramental books, and later some books which already collected was revised into Sacraments.
