When the Bible makes threats and promises to church communities, with a few exceptions, it is always speaking to this community. Most of the seven churches in Revelation are gone today because of various reasons of infidelity. Jesus gave specific warnings to them, which they either heeded or didn’t. Paul tells the specific church of Rome that it can be cut off. Protestants get accused of saying that “the church fell after the apostles” (though I don’t know any Protestant who actually says that), but it seems like Paul is saying precisely that.
Of course, there are promises in Matthew 16 and 28 that talk about what looks like the church in general. Given the above, this easily fits within an invisible/visible church narrative.
