I Corinthians 6:19

Your body is the temple of the Holy Ghost - What an astonishing saying is this! As truly as the living God dwelt in the Mosaic tabernacle, and in the temple of Solomon, so truly does the Holy Ghost dwell in the souls of genuine Christians; and as the temple and all its utensils were holy, separated from all common and profane uses, and dedicated alone to the service of God, so the bodies of genuine Christians are holy, and all their members should be employed in the service of God alone. And ye are not your own? - Ye have no right over yourselves, to dispose either of your body, or any of its members, as you may think proper or lawful; you are bound to God, and to him you are accountable.

What? know ye not? &c.--Proof that "he that fornicates sinneth against his own body" (Co1 6:18). your body--not "bodies." As in Co1 3:17, he represented the whole company of believers (souls and bodies), that is, the Church, as "the temple of God," the Spirit; so here, the body of each individual of the Church is viewed as the ideal "temple of the Holy Ghost." So Joh 17:23, which proves that not only the Church, but also each member of it, is "the temple of the Holy Ghost." Still though many the several members form one temple, the whole collectively being that which each is in miniature individually. Just as the Jews had one temple only, so in the fullest sense all Christian churches and individual believers form one temple only. Thus "YOUR [plural] body" is distinguished here from "HIS OWN [particular or individual] body" (Co1 6:18). In sinning against the latter, the fornicator sins against "your (ideal) body," that of "Christ," whose "members your bodies" are (Co1 6:15). In this consists the sin of fornication, that it is a sacrilegious desecration of God's temple to profane uses. The unseen, but much more efficient, Spirit of God in the spiritual temple now takes the place of the visible Shekinah in the old material temple. The whole man is the temple; the soul is the inmost shrine; the understanding and heart, the holy place; and the body, the porch and exterior of the edifice. Chastity is the guardian of the temple to prevent anything unclean entering which might provoke the indwelling God to abandon it as defiled [TERTULLIAN, On the Apparel of Women]. None but God can claim a temple; here the Holy Ghost is assigned one; therefore the Holy Ghost is God. not your own--The fornicator treats his body as if it were "his own," to give to a harlot if he pleases (Co1 6:…

What? know ye not that your body is the temple of the Holy Ghost,.... What is said in Co1 3:16 of the saints in general, is here said of their bodies in particular. The Holy Spirit, in regeneration and sanctification, when he begins the good work of grace on a man, takes possession of his whole person, soul and body, and dwells therein as in his temple. So the Jews (o) call the body of a righteous man the "habitation" of the Holy Spirit. Now it is most abominably scandalous and shameful that that body, which is the dwelling place of the Holy Spirit, which is sacred to him as a temple, should be defiled by the sin of fornication: it is added, which is in you, which ye have of God; meaning the Holy Spirit which was in them, as in his temple; which dwelt in their hearts, and influenced their bodies, lives, and conversations; and which they received of God as a wonderful instance of his grace and love to them; that he should be bestowed upon them, to regenerate, renew, and sanctify them, to implant every grace, to make them a fit habitation for God, and meet for the inheritance of the saints in light: and ye are not your own: their own masters, at their own dispose, to live to their own lusts, or the lusts of men; men have not power over their bodies to abuse them at pleasure by fornication, or such like uncleanness, neither single nor married persons; see Co1 7:4 and of all men, not the saints, who are neither their own nor other men's, nor Satan's, but God's; not only by creation, but by choice and covenant; and Christ's by gift, by purchase, and powerful grace, and in a conjugal relation to him; wherefore fornication ill becomes them.

In this chapter the apostle, I. Reproves them for going to law with one another about small matters, and bringing the cause before heathen judges (Co1 6:1-8). II. He takes occasion hence to warn them against many gross sins, to which they had been formerly addicted (Co1 6:9-11). III. And, having cautioned them against the abuse of their liberty, he vehemently dehorts them from fornication, by various arguments (Co1 6:12 to the end).
