a. "Made under the law" (Galatians 4:4) means Christ was "made" under the Jewish ordinances.
b. "Made under the law" in Gal. 4:4 means Christ was made under the Jewish ceremonial law (cf. commentary on the text, 6BC 966).
c. "Made under the law" in Gal. 4:4 means under the condemnation of the moral law. Thus Christ was expressly not "exempt" from nothing, but chose not to sin. Both Substitute and Exemplar.
