[T]he Hebrew word for ‘image’ is also employed by P of Seth’s likeness to Adam (Gen 5.3), following a repetition of Genesis 1’s statement that humanity was created in the likeness of God (Gen. 5.1), which further supports the notion that a physical likeness was included in P’s concept. It is also noteworthy that the prophet Ezekiel, who was a priest as well as prophet at a time not to long before P, and whose theology has clear parallels with P’s, similarly speaks of a resemblance between God and the appearance of man. As part of his call vision in Ezek. 1.26, he declares of God, ‘and seated above the likeness of a throne was something that seemed like a human form’ (the word demut, ‘likeness’, is used, as in Gen. 1.26). Accordingly, there are those who see the image as simply a physical one. However, although the physical image may be primary, it is better to suppose that both a physical and spiritual likeness is envisaged, since the Hebrews saw humans as a psycho-physical totality.
The use of selem elsewhere in Genesis and of demut in Ezekiel certainly tells against the view of those scholars who see the divine image in humanity as purely functional in nature, referring to humanity’s domination over the natural world that is mentioned subsequently (Gen. 1.26, 28), an increasingly popular view in recent years. Although the two ideas are closely associated, it is much more likely that humanity’s rule over the world (Gen. 1.26-28) is actually a consequence of its being made in the image of God, not what the image itself meant.
