Whenever people say church they either mean a building where religious activity happens, or the hierarchy which runs the religion.
Which is way different than what I mean by it. Or what Jesus and the bible mean by it. When Jesus says ἐκκλησία/ekklisía he means a flock of Christians; a group, assembly, crowd, congregation, collection, bunch, congress, whatever term you wanna use for many of us. People like to take apart that Greek word, and note its word-root is καλέω/kaléo, “to call”—and then analyze the significance of Jesus calling Christians to meet together. Yeah, whatever: By the time people used the word in Jesus’s day, it just meant a gathering. And that’s still what it means.
Still, even Christians tend to use it to mean a church building, or the church leadership. Which is why we tend to forget we are the church. Church isn’t a separate thing from us; it is us. It’s us collectively; it’s why I can’t say “I am the church,” because I all by myself am definitely not the church: Other Christians have to be in it. At least two or three. Mt 18.20 The more the better.
Typically “church” refers to a local group. But sometimes we use the word to refer to every Christian, everywhere: The universal church. The catholic church (as opposed to the Roman Catholic Church, which is only one church within the universal church, although frequently they forget this). Every human who has a connection with Christ Jesus and is part of his body. It’s hardly limited to one sect or denomination; Orthodox Christians are not the only Christians on the planet. Neither are Lutherans, Episcopalians, Baptists, Calvinists, charismatics, Fundamentalists, Emergent Christians, nor Purpose-Driven™ Christians. (Though sometimes we certainly act like it.) We aren’t saved by our affiliations or theology; we’re saved by God through Christ Jesus, and we’re in his kingdom because God adopted us and recognizes a valid, living relationship with us.
Of course, since many Christians are under the delusion we determine who’s a “real Christian” and who isn’t, we tend to limit the universal church to our definitions. If we’re pretty sure real Christians only vote the way we do, every Christian in the opposition party isn’t a real Christian, so they don‘t count as part of Jesus’s universal church. If we’ve got certain doctrines we feel every real Christian holds to, we figure everyone who believes otherwise is heretic, and by definition heretics can’t be in the true church. And so forth. Various Christians like to refer to the visible church, the 2 billion people worldwide who publicly claim allegiance to Jesus, and the invisible church, the unknown number of people whom Jesus really recognizes as his. Depending on how optimistic or pessimistic they are, either the visible church is way bigger than the invisible, or vice-versa.
Meh. I’ve no idea how many people Jesus actually intends to let into his kingdom. I’m an optimist, so I figure God’s way more gracious than we are, and is gonna save way more people than we expect. Not everybody; not that he doesn’t want to; he warned us there are gonna be holdouts. But he doesn’t limit his kingdom like we do. So I expect there’s significant overlap between the visible and invisible churches; and when I say “kingdom” I typically mean his invisible church, which is represented by the 2 billion professing Christians.
