In the early church, cults were managed by Ecumenica councils of the church. Most of the cults alter the interpretation of the bibles and perceive it in their own language and idea. They at a times perform true Christianity by sharing with the poor and doing charity work. Cults alienates one from the love of God and they later die and the word of God remains.
In genesis 1;1 God is the creator of heaven and earth. This is what orthodox church believes. They believe that God made everything on earth. Consequently, they believe that the bible reveals God himself and the salvation rather than scientific booklet as other Christians believe.
