Was Adam anatomically God's image, as Michelangelo's painting seems to indicate? Under the patronage of Pope Julius circa 1512, Michelangelo painted The Creation of Adam, seen below, in the Sistine Chapel. The painting shows both God and Adam as adult men with navels, and the complementary poses of the two figures allude to the verse, "God created man in his own image, in the image of God he created him" (Gen 1:27)



Does the Catholic Church endorse this painting as an accurate representation of Adam's creation? How is the presence of navels consistent with neither Adam nor God being born of a woman? Was Adam created in the anatomical image of God?
The Catholic Church (my own Tradition) believes that being made in God's image does not have such a physical reality. This 'image' is more a reflection of His own Nature. The closest physical way we 'image' God is that humans are both Male and Female who come together to generate a Third person. This "The Two Become One" is reflecting the Trinitarian Nature of God; where the Holy Spirit proceeds "From the Father and the Son".

God also has no real gender in the same sense that humans have gender. Human gender is a creation of God; which fits into His design of creation. God does ask us to call him Father, and yes, the second person of the Trinity did appear on earth in a Male body; but human Fatherhood and human Sonship are only shadows of God's Perfect Fatherhood and Perfect Sonship. God, aside from the incarnation, as no physical body composed of matter.

One thing I have realized about the various paintings in Catholic Churches is that angels and even God himself (the Father) are depicted as human. This isn't because they 'look' like that; rather the artist is expressing the idea that "These are Persons". Angels are persons: They are pure intellect (and no physical body), and with intelligence comes personality. How much more so for God?

There are more ways that humans 'image God', but I only gave you the ways concerning physical appearance since that is what you are concerned with. I hope this helps.
