-A8
And I told you which one it couldn’t be.
Jesus said, “Those who are not against us are for us.”
That’s early in the gospel of John. Should I look it up. Therefore, it’s inappropriate to put restrictions on saying that all true believers are His church.
I would encourage you to look at the notion advanced in Rev 2 that a “church” can have its candlestick removed. In other words, it is no longer “light,” so why waste a perfectly good candlestick.
