The Holy Church followed a doctrine that stated humans were above all other species, and preached that humans should reign supreme. Those who were discovered to have the power to use Ancient Magic from the age of the gods, or special magic that only monsters could use, were once considered to be god’s descendants and taken under its protection. Anyone caught insulting the Holy Church would be tabled a heretic and immediately be executed. In addition, anyone that would protect them would also be considered a heretic.
The main purpose of the Holy Church was to manipulate the humans of Tortus for Ehit's twisted game. Because of this, most (if not all) conflicts in Tortus's history were caused by the Holy Church under Ehit's order. This includes the suffering and near extinguish of many races such as the Beasmen, Vampires and Dragonmen. They would likewise enforce their control over everyone on Tortus, not allowing anyone who's extremely powerful to live outside of their dominance. This is shown when they declared Hajime Nagumo and his party heretic.
Many of the high ranking members of the Holy Church were extremely devoted to Ehit and wouldn't hesitate to use the lives of many innocent people just for the sake of their own agenda. Even worse, during the demon invasion on Heiligh Kingdom, all the high ranking members of the church chose to abandoned the kingdom during the invasion because Ehit supported it. While there have been some who spoke out against the Church's teaching among it ranks (such as Simon), they are usually banished under the church's authority. During the war, the Church's temple was destroyed by both Tio and Aiko purposely killing the pope and his bishops within the destruction of the temple.
However, when they learned from both Aiko and Lilliana of being pawns in the "God's" game, the redeemed Holy Church lost all of their faiths and respects for Ehit leaving Tortus as a godless world. While no longer worshiping Ehit anymore, they completely abandoned their decree and teachings hoping to reconcile their relationship with Beastmen. Instead of seeking a god or goddess, they now worships Aiko as their "Goddess of Victory".
The Holy Church was the dominant authority throughout most of Tortus' northern hemisphere, which was primarily populated by humans. They would have a cathedral built in the major cities of every nation under their dominion.
The Templar Knights were the church’s regular army. They were split into four divisions during the age of the Liberators. Members of the Templar Knights who showed exceptional promise were promoted to one of the orders that comprised the "Three Pillars of Radiance":
The first order was the Paladins. They were responsible for guarding the pope and other important religious figures. Though they were the smallest of the orders, each member of the Paladins possessed powerful special magic that could rival even ancient magic.
The second order was the Paragons of Light. They were in charge of capturing, taming, and raising the powerful beasts that the other orders used as mounts. They were the weakest of the three pillars, but also the most versatile.
The third order was the Holy Templar Knights. They were the most powerful and had roughly 300 members. They were described as the "incarnation of God's will", and were only active whenever they would receive Ehit's decree.
It is unknown how to Holy Church came in existence, but they eventually became to dominant religious and political entity among the humans of Tortus. As they enacted Ehit's will, they had orchestrated the rise and fall of many nations throughout history. They even had their own nation called the Elbard Theocracy where the pope also served as its king, though it too would eventually fall.
By the time the Heroes of Earth were summoned to Tortus by Ehit, the church still remained the dominant authority, with over 90% of humans worshiping them and Ehit.
