I’d like to offer a different perspective. It isn’t exactly a theological case, though not because there isn’t one. As I’ve written elsewhere, theologically speaking, there is one reason and one reason only to go to church: God.
If the God of the gospel is the one true and living God, then every one of us should be at church every Sunday morning (and more). If not—if Jesus did not rise from the dead—then the church is built on a lie, our faith is futile, and “we are of all people most to be pitied” (1 Cor. 15:16–19). If the gospel were false, church would be a waste of time, even if it added decades to our lives and absolutely ensured our total personal flourishing. If the God of Abraham is fictional, if he is not the maker of heaven and earth, it would be better to live in the truth and be miserable than to playact the liturgy and be happy.
But by definition, Christians believe the gospel is true. And if it is true, then church—“the church of the living God, the pillar and bulwark of the truth” (1 Tim. 3:15, NET) and Christ’s “body, the fullness of him who fills all in all” (Eph. 1:23, ESV)—is a vital element of human life lived to the utmost.
That’s why the instinct to meet our culture’s critique or ignorance of the church by downplaying its import is so misguided. Church is not an optional add-on to Christian faith. It is how we learn to be human as God intended. Indeed, it makes possible truly human life before God.
