Shared ground
Paul’s point is about the Corinthian community, not merely a religious building. He says “you” are God’s temple and that God’s Spirit lives “in you” (plural), describing God’s real presence among them. That claim is presented as something they should already understand (“Don’t you know…”).
Because the community is God’s temple, Paul treats damage to the community as damage to something that belongs to God and is marked off for God. That is why the warning is so severe: the one who “destroys” God’s temple will face God’s own opposition in a matching way.
Where interpretation differs
Who “you” refers to. Many read the “temple” mainly as the whole gathered church (the local community as a unit). Others also see an implication for each believer, since the Spirit is said to live “in you,” and elsewhere Paul can speak of the body in temple terms. Still, in this immediate context the main “you” is the group.
What “destroy” means. Some take it as actions that fracture and ruin the church—division-making, corrupt teaching, or leadership that tears down rather than builds up. Others include severe moral corruption that poisons the community. A smaller number also extend it to literal physical harm, but the surrounding context about “building” and factionalism makes community-damaging behavior the most direct target.
What “God will destroy him” refers to. Some understand it as God’s future judgment in the end. Others take it as a broader principle that God may also act within history to oppose and bring down those who devastate the church. The text itself does not specify timing; it stresses certainty and seriousness.
Why the disagreement exists
The Greek “you” can be plural while still sounding singular in English, and Paul uses temple language in more than one way in his letters. Also, the verb translated “destroy” can carry the sense of “ruin/corrupt,” which can be applied to different kinds of harm (relational, doctrinal, moral, or even physical). Finally, Paul’s wording about God’s response is absolute but not time-stamped.
What this passage clearly contributes
Explicitly, Paul identifies the Corinthian believers together as of God, states that God’s Spirit dwells among/in them, calls that temple “holy” (set apart), and warns that God will oppose and bring down the person who ruins God’s temple (1 Corinthians 3:16–17). As theological inference, the passage frames church life as sacred space under God’s protection, making the integrity of the community a matter of direct accountability to God, not merely interpersonal preference or social politics.
