Imago Dei is taken from the Latin meaning the "Image of God". This concept and theological doctrine states that human beings are created God's image and therefore have inherent value independent of their utility or function.
The term imago Dei refers most fundamentally to two things: first, God's own self-actualization through humankind; and second, God's care for humankind. To say that humans are in the image of God is to recognize the special qualities of human nature which allow God to be made manifest in humans. In other words, for humans to have the conscious recognition of their being in the image of God means that they are the creature through whom God's plans and purposes can be made known and actualized; humans, in this way, can be seen as co-creators with God. The moral implications of the doctrine of imago Dei are apparent in the fact that if humans are to love God, then humans must love other humans, as each is an expression of God. The human's likeness to God can also be understood by contrasting it with that which does not image God, i.e., beings who, as far as we know, are without self-consciousness and the capacity for spiritual/ moral reflection and growth. Humans differ from all other creatures because of their rational structure - their capacity for deliberation and free decision-making. This freedom gives the human a centeredness and completeness which allows the possibility for self-actualization and participation in a sacred reality. However, the freedom which makes the human in God's image is the same freedom which manifests itself in estrangement from God, as the myth of the Fall (Adam and Eve) exemplifies. According to this myth, humans can, in their freedom, choose to deny or repress their spiritual and moral likeness to God. The ability and desire to love one's self and others, and therefore, God, can become neglected and even opposed. Striving to bring about the imago Dei in one's life can be seen as the quest for wholeness, or one's "essential" self, as pointed to in Christ's life and teachings.
Imago Dei
Imago dei is the biblical belief that humans are created in the image of God. God is not human. But humanity is created in God's image. From this we know that humans are not physically in God's image but spiritually made in His Image. This means that humans have a limited amount of his invisible attributes. This amount of attributes are enough according to the bible for humans to be called created in the image of God. This is not saying humans are Gods. But humans are linked to God by the invisible gifts he has given them. These invisible gifts may be creativity, imagination, the ability to think, reason, and so on.
