Galatians 3:28

There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.

There is in [ eni (G1762)] this sonship by faith in Christ no class privileged above another, as the Jews under the law were above the Gentiles (Romans 10:12; 1 Corinthians 12:13; Colossians 3:11).

Bond nor free - Christ belongs by faith to the "bond" as much as to the "free." Notes, 1 Corinthians 7:21; Ephesians 6:8.

Neither male nor female - Greek, 'there is not male AND female.' Alterable social distinctions are contrasted by "neither ... nor:" the unalterable human one of sex, by "and" (Mark 10:6). Male and female form a unity, the one supplementing the other. There is no distinction, spiritually, into male and female. Difference of sex makes no difference in Christian privileges. But under the law the male had great privileges. Males alone had in their body circumcision, the sign of the covenant, (whereas baptism applies to male and female alike); they alone were capable of being kings and priests, whereas all of either sex are now "kings and priests unto God" (Revelation 1:6); they had prior right to inheritances. In the resurrection the relation of the sexes shall cease (Luke 20:35).

One, [ heis (G1520)] - 'one man;' masculine, not neuter; "one new man" in Christ (Ephesians 2:15).
