David,
Please allow me to reason with you for just a bit about there being no church in the Old Testament. Several months ago I brought Acts 7:38 up to you, and you never responded. You assert things that you need to prove to the frustration of many of our participants. I even wrote to you privately to discuss your tendency to state your views as fact even when your view is the subject under debate. Among many other things I said, "Just repeating your view doesn't lend itself to debate." You only answered that you were referencing the 1689 Confession.
So here's the verse again. Please tell us why there was no church in the wilderness.
Acts 7:38
This is he, that was in the church [ἐκκλησία] in the wilderness with the angel which spake to him in the mount Sinai, and with our fathers: who received the lively oracles to give unto us:
Here's another thought.
Paul is writing to the Ephesian Gentiles (vs. 11) welcoming them into full membership of "the covenants of promise" (vs. 12)
Notice also that Paul says that there is one "holy temple" made up of all believers, past and present, Jew and Gentile.
Ephesians 2:19-21
19 So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God,
20 built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone,
21 in whom the whole structure, being joined together, grows into a holy temple in the Lord.
Another question.
Who do you think the 24 elders are in Revelation? There were 12 Apostles and 12 what? You can say it, David. It's not that hard. I think the 24 together picture to whole Church from the Adam to eternity. 12 Apostles plus the 12 Patriarchs. (See Revelation 4)
