[GoLightly]

How exactly does one speak to the "CHURCH UNIVERSAL" (i.e. the set of all believers)?

Just say it in a language that a small percentage of the people understand & say you've done it.

Speaking to another person is not speaking to the set of all believers. My point to Quix is that the idea that the Church is the set of all believers is completely foreign to the NT, and makes no sense of verses like Matt 18:17.
