covered in leather (the skin of a dead animal) because the Word of God is considered to be life-giving. Traditionally, the Gospel is covered in gold or cloth. Eastern Orthodox Christians are encouraged to read and study the Bible daily, especially making use of the writings of the Holy Fathers for guidance. Recent essays have been written by various contemporary Eastern Orthodox scholars which attempt to reconcile and react to both the creationist interpretation of Genesis 1-2 and the Darwinian theory of human evolution. God Trinity Eastern Orthodox Christians believe in a monotheistic conception of God (God is only one), which is both transcendent (wholly independent of, and removed from, the material universe) and immanent (involved in the material universe).

Throughout the ages this has been a point of contention between schismatic Christian theological factions (heterodox) and the mainstream body of Christian believers (orthodox). Christ had a divine will, or set of desires and spiritual incentives, and a human will with fleshly drives. He had
