Also, the Lord's Supper, well, was actually a supper, both originally with the twelve (i.e., you know, the “last” one) and as the church had been gathering in the New Testament and unto about 300 AD. Also we have the Marriage Supper of the Lamb (Revelation 19:6ff.) as a picture of the gathered-church from all ages at the end of time (as we know it). Listen to how God through Isaiah the prophet (25:6-9) envisioned the future of His gathered-people:
On this mountain the Lord of hosts will make for all peoples
These pictures demonstrate that to be church (i.e., the gathered-church) was both local and missional in nature. We need to reimagine church.
