Mike's conclusion assuming Junia was an apostle: she was a missionary, not highest-rank

Even granting that Junia was a female apostle, the majority view is correct: she was not an apostle like the Twelve or Paul. Neither she nor Andronicus appear in Acts or any other context. Two obscure apostles being more notable than the Twelve without any mention elsewhere is very unlikely. The word apostle has legitimate varied meanings, leaning toward 'missionary.' Even several egalitarians (Linda Belleville) agree she became Christian only at Pentecost. Junia was reasonably a missionary, possibly focused on women's ministry.
