Ephesians 5:32 (ESV) This mystery is profound, and I am saying that it refers to Christ and the church. This verse is talking specifically about marriage! Paul says, “This mystery of marriage is profound, it refers to Christ and the church.” Paul is revealing that marriage is God’s created relationship reflecting Christ and his church! This great eternal secret reveals God’s purpose for mankind. Paul declares this mystery just after quoting Gen.2:24, “Therefore a man shall leave his father and mother and hold fast to his wife, and the two shall become one flesh” which clearly shows that the unity of marriage reflects unity between Christ and the church. They are one!
