Ephesians 5:29-32 NIV
29 After all, no one ever hated their own body, but they feed and care for their body, just as Christ does the church— 30 for we are members of his body. 31 “For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.” 32 This is a profound mystery—but I am talking about Christ and the church.
In this passage, Paul is confusing. He changes gears talking about marriage then says he is really talking about Christ and the church. Why?
