What is biblical equality? It is the belief that all people are equal before God and in Christ. All have equal responsibility to use their gifts and obey their calling to the glory of God. God freely calls believers to roles and ministries without regard to class, gender, or race. We believe this because the Bible and Jesus Christ teach it to us.
Explorations of Genesis 2 intent on recovering God's ideal for the interrelationship between male and female often zoom in on the creation of Eve. We are better able to appreciate how the narrative supports that ideal when we engage the whole chapter.
"Although the people living in the Greco-Roman world might not have been able to imagine a world in which slavery does not exist, Paul’s churches leave the hierarchy of slavery behind as part of the world that is passing away, along with ethnic division and gender hierarchy. Paul removes the power differential from Philemon and Onesimus’s relationship (in their church), and he replaces that differential with koinōnia by asking Philemon to receive Onesimus as if he were Paul."
