Genesis 1:27 says that humanity was created in God’s image.
For me, the key revelation here is in which definition is used for “man”. Just like in English, “man” can be the singular, the species, the male gender, or the collective members of any of those other definitions. But the reading I find epiphanous is “man” referring to the collective members of the group. The scripture isn’t informing us so much that God has 10 fingers and toes and all that so he made us that way (i.e. the “species” reading, although I’m sure that reading is also valid), but that God is a community of beings working together in perfect harmony, and so he always intended for mankind to be the same way.
