ISB ~ 1 Corinthians 6 v13

The body . . . for the Lord:Paul hints that just as the body of a bride belongs to her husband through the covenant of marriage (7:4), so the body of the believer is consecrated to Christ through Baptism (6:11). Christ’s spousal right over the body is thus violated when believers are involved in sexual impurity—a fact that makes promiscuity equivalent to adultery (2 Cor 11:2-3).

The general resurrection puts this moral crisis in perspective:because our bodies belong to the Lord and are destined for eternity, they should not be desecrated by evildoing (1 Cor 6:14; CCC 796, 989, 1004).
