Imago Dei ("image of God")
Is a theological term, applied uniquely to humans, which denotes the symbolical relation between God and humanity. The term has its roots in Genesis 1:27, wherein "God created man in his own image. . ." This scriptural passage does not mean that God is in human form, but rather, that humans are in the image of God in their moral, spiritual, and intellectual nature. Thus, humans mirror God's divinity in their ability to actualize the unique qualities with which they have been endowed, and which make them different than all other creatures: rational structure (see logos), complete centeredness, creative freedom, a possibility for self-actualization, and the ability for self-transcendence.
