“Imago Dei” comes from the Latin version of the Bible, translated to English as “Image of God.”
"Image of God" is defined as the metaphysical expression, associated uniquely to humans, which signifies the symbolical connection between God and humanity.
The phrase has its origins inGenesis 1:27, wherein "God created man in his own image..." This biblical passage does not imply that God is in human form, but that humans are in the image of God in their moral, spiritual, and intellectual essence.
Thus, humans reflect God's divine nature in their ability to achieve the unique characteristics with which they have been endowed.
These unique qualities make humans different than all other creatures: rational understanding, creative liberty, the capacity for self-actualization, and the potential for self-transcendence.
