Homoiōma
Homoiōma (ὁμοίωμα) is a Greek neuter noun for "likeness" which is particularly common in Jewish Koine Greek texts. The meaning of the word in several well-known New Testament verses is related to discussion in Christology about the relation of Christ to man. Etymology. The noun comes from the adjective "homoios", "like". Usage. Classical usage. Use of the word as "image" is relatively common in Attic texts; the use in the singular is found in Plato ("Phaedra" 250a) and Aristotle ("Rhetorica" 1356a31). The word is found in inscriptions on ostraca and in the Tebtunis papyri. Septuagint usage. The word  is more common in Jewish usage than pagan. It appears frequently in the Septuagint, often in relation to idols. The term is used by Josephus in a similar way. The essential contrast is between the reality of God and a "homoiōma" or artifice. The representation may be two-dimensional such as a diagram graffiti or mural or three-dimensional such as carvings or figurines. The word may also be used in a qualitative or figurative sense; men "like the son of a king", daughters "adorned like a temple" creatures "with the likeness of a man." or, in Sirach as the  likeness ("homoiōma") of a face to a face. New Testament usage. The word appears 6 times in the New Testament and in the KJV is rendered "likeness" "made like to" "similitude" and "shape". Two of these uses are fairly straightforward, following directly on from Septuagint usage - idols in the "likeness" of animals, and locusts with the "likeness" of horses. Another; a sin in the likeness of Adam's sin, is understandable within secular Greek usage. This leaves three other uses, one the "likeness" of death in Rom 6:5, two more in Paul's description of the "likeness" of Christ to  other men. Interpretation. The "likeness" of death. In Romans 6:5 Paul introduces the concept of "homoiōma" between Christians and Christ in a grammatical structure which although it only employs the word once, duplicates it with a double "of his death...also [in the likeness] of his resurrection" The "likeness" of sinful flesh. Discussion in Christology centres on the significance of "homoiōma" in the writings of Paul, and in particular whether "homoiōma" in Romans 8:3 and Philippians 2:7 indicates a merely external or internal likeness with other men. Moo (1996) in discussing Romans 8:3 maintains that Paul cannot mean that  Christ had only the "appearance" of sinful flesh. yet the meaning is constrained by the need to balance Paul's use of the same word in Philippians 2:7. Eucharist. In Patristic usage, and later in Greek Orthodox tradition the concept of "homoiōma", being more than just external likeness, is developed in concepts of eucharistic prayer and the rite of the eucharist.
