The Golden Chain - Robert J. Wieland

Philippians 2:7, where he says that Christ was
"made ... in the likeness of men." Thus the word
cannot mean mere appearance or outward form. To
interpret it so in Philippians would be the heresy of
Docetism (which denies the true humanity of
Christ). If the word "likeness" means reality in
Philippians it must also mean reality in Romans. It
was in His human flesh that Christ "condemned
sin." The sinless Adam had no such problem in his
flesh. It would be unnecessary and even impossible
for Christ to "condemn sin" in sinless flesh, for
such would be meaningless and irrelevant to us.
Since Christ already "had" a sinless nature, the
only nature He could "take" would be our sinful
nature.
Hebrews 2 enlarges on this idea. "Jesus ... was
made a little lower than the angels, for the
suffering of death" (verse 9). As man is since he
became subject unto death, this is what we "see
Jesus" to be. Death could not have touched Him
had He come in the sinless nature of Adam before
the Fall. He "took not on Him the nature of angels:
but He took on Him the seed of Abraham" (verse
26
