The apostle was reading the archives of the church:
"10000 years ago the world was ruled by witches. They numbered only in thousands but controlled millions of lives. If you disrespected any witch your whole family would be destroyed. If you had a daughter with witch power you have to offer her to the Witch Association. Witch Association also collected boys. If they were lucky they were used as a sacrifice and died young. Some were used as slaves for years before being tortured to death.
Few people knew that a man ruled the association. When he just created the Witch Association he wanted to help people and with the help of witches' power he helped a lot of people. But over the time he got bored and the power corrupted him. He began to think about the life, what is life, why have I come into this world? Unknowingly he began to believe that he's a strongest so he's a god. Since he was the strongest he can do anything he wishes for. So Witches Association instead of helping people started to abuse them.
Witches rule went on for 1000 years, after which a rebellion took place. Witches were very strong, 1000s of people died to kill just one witch. Then after some time an organization was built to fight the churches. It captured newly awakened witches and experimented on them, they also brainwashed other witches to join them. It was cruel but anything to fight the witches. Over the time because the witch population kept decreasing and human advancement on witch magic they won the war. Millions of lives were lost in that war that lasted for 100s of years.
After the war the organization proclaimed itself as church. It helped to rebuild the human nations, helped people in need. The churches one of the roles was to prohibit of another witch organization."
