ISB ~ 1 Corinthians 6 v17

one spirit with him:The point is, not that sexual union (6:16) is a mere reflection of our spiritual union with Christ, but that even our bodies become united with Christ through the Spirit (15:45). This union with Christ’s humanity—which is sacramental, not sexual—has its beginning in Baptism (12:13) and is strengthened by the Eucharist (10:16-17).
