Marriage and the Mystery of Christ and the Church
Ephesians addresses wives and husbands within the preceding call to Spirit-filled life and submission. Husbands receive an especially extensive command: love their wives as Christ loved the church and gave himself for her, nourishing and cherishing rather than exploiting. Paul describes Christ sanctifying and cleansing the church with “the washing of water by the word,” then quotes Genesis 2:24—two becoming one flesh—and declares that the mystery is great because he is speaking about Christ and the church.
