Being an individual member of the Body of Christ =/= “I are Church”
Sure it does.
Individuals make up the body of Christ.
That isn’t what’s being said, obviously. Only that the Church isn’t a building but those who have been saved. The Church is the Bride of Christ, so similarly we should think of ourselves as both, although of course we know individually that we aren’t the only person. The body of Christ has parts, and Paul talks about there being parts to the body, but if someone touches another person’s arm, it’s accurate to say either that the person touched the other person’s arm, or simply touched the person.
