Biblical Answer

The concept of "one flesh" is deeply rooted in the biblical understanding of marriage. The phrase is first introduced in Genesis 2:24, where it is stated that "a man shall leave his father and mother and be joined to his wife, and they shall become one flesh." This passage sets the foundation for the biblical understanding of marriage as a union between two people who become one in body, mind, and spirit. In this context, "one flesh" refers to the personal union of a man and woman at all levels of their lives, including their physical, emotional, and spiritual aspects.

The concept of "one flesh" is further developed in Ephesians 5:28-32, where Paul describes the relationship between Christ and the church as a mystery that is revealed in the marriage relationship. He writes that the relationship between a husband and wife is a symbol of the relationship between Christ and the church, and that this relationship is characterized by a deep and intimate union. In this context, "one flesh" refers to the spiritual union that exists between a man and his wife, and between Christ and the church.

In the context of marriage, the phrase "one flesh" points to the physical intimacy that is a part of the marriage relationship. This is suggested by the reference to nakedness in Genesis 2:25, and is further emphasized by Paul's warning in 1 Corinthians 6:16 that a man should not unite with a prostitute physically unless he is also willing to unite with her in a spiritual sense. In this sense, "one flesh" refers to the physical and emotional union that exists between a man and his wife, and is a key aspect of the biblical understanding of marriage. Overall, the concept of "one flesh" is a rich and multifaceted one that speaks to the deep and intimate union that exists between a man and his wife, and between Christ and the church.
