I Corinthians 3:17

If any . . . defile . . . destroy--rather as the Greek verb is the same in both cases, "destroy . . . destroy." God repays in kind by a righteous retaliation. The destroyer shall himself be destroyed. As temporal death was the penalty of marring the material temple (Lev 16:2; Dan 5:2-3, Dan 5:30), so eternal death is the penalty of marring the spiritual temple--the Church. The destroyers here (Co1 3:16-17), are distinct from the unwise or unskilful builders (Co1 3:12, Co1 3:15); the latter held fast the "foundation" (Co1 3:11), and, therefore, though they lose their work of superstructure and the special reward, yet they are themselves saved; the destroyers, on the contrary, assailed with false teaching the foundation, and so subvert the temple itself, and shall therefore be destroyed. (See on Co1 3:10), [ESTIUS and NEANDER]. I think Paul passes here from the teachers to all the members of the Church, who, by profession, are "priests unto God" (Exo 19:6; Pe1 2:9; Rev 1:6). As the Aaronic priests were doomed to die if they violated the old temple (Exo 28:43), so any Christian who violates the sanctity of the spiritual temple, shall perish eternally (Heb 12:14; Heb 10:26, Heb 10:31). holy--inviolable (Hab 2:20). which temple ye are--rather, "the which (that is, holy) are ye" [ALFORD], and, therefore, want of holiness on the part of any of you (or, as ESTIUS, "to tamper with the foundation in teaching you") is a violation of the temple, which cannot be let to pass with impunity. GROTIUS supports English Version.

In this chapter the apostle, I. Blames the Corinthians for their carnality and divisions (Co1 3:1-4). II. He instructs them how what was amiss among them might be rectified, by remembering, 1. That their ministers were no more than ministers (Co1 3:5). 2. That they were unanimous, and carried on the same design (Co1 3:6-10). 3. That they built on one and the same foundation (Co1 3:11-15). III. He exhorts them to give due honour to their bodies, by keeping them pure (Co1 3:16, Co1 3:17), and to humility and self-diffidence (Co1 3:18-21). IV. And dehorts them from glorying in particular ministers, because of the equal interest they had in all (Co1 3:22 to the end).
