For most American fundamentalists, the Greek Orthodox Church is utterly strange and foreign. Few fundamentalists read Orthodox material and even fewer understand it. For a good introduction into the East, read Understanding the Greek Orthodox Church, by Demetrios J. Constantelos, currently in its fourth edition.
The two channels by which truth is conveyed represent the two aspects of God’s involvement in history, the visible and the invisible, the physical and the metaphysical. God as Spirit, Power, and Essence is invisible but God as creative energy active in creation is visible and physical. God as the ultimate cause of laws, decrees, principles of morality, the urge of the human person to seek communion with the divine, the desire of the human being to rise about nature, is revealed in the world through various ways and diverse manners. Because of the commonality between divinity and humanity, man reachers out for God and when the reach becomes unattainable, God reaches out for man. This is the background of the Greek Orthodox belief that there is a natural and supernatural revelation of truth.
