Christ and the church broke the social rules of HIS day.  He gave honor and rights to groups that were not very high on the social ladder.

He recognized women as important.  Women were among his followers and special mention is made of them in the gospels.  In 1 Timothy  speaks of deaconesses and 1 Corinthians 7 protects womens marital rights.

In Philmon Paul urges his friend to treat his servant with honor, love and respect.

Galatians 3: 28 There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.
