Comprehensive list of differences between wives and slaves in Scripture

Wives vs slaves: (1) wives are a natural part of the home, slaves are not; (2) wives submit differently than slaves who follow all orders; (3) wives are one flesh with husbands (head-body, Christ-church), slaves are not one with masters; (4) wives' roles are due to created order, slaves' roles are purely situational; (5) wives' roles are desirable and good, slaves' situation is unfortunate ('if you can get free, go'). The only connection in Ephesians is that all three pairs involve some form of submission.
