Worship and Communion in the Early Church (1Corinthians 11:26)

Proclaiming the Lord's Death (11:26)
Verse 26 is not part of the Words of Institution, but a comment upon them. Let's look at this sentence in detail:
"For whenever you eat this bread and drink this cup, you proclaim the Lord's death until he comes." (11:26)
"Proclaim" (NIV, NRSV) or "shew" (KJV) is katangellō, "to make known in public, with implication of broad dissemination." The word is frequently used in the literature of public decrees. Every time we partake of the Lord's Supper, we hear a clear explanation of Jesus' death for our sins. In our day, when unbelievers are sometimes present at the Lord's Supper, they hear the gospel, and though they are not invited to partake, they gain understanding into what Christ's death means for them. Just like baptism is an enacted proclamation of cleansing from the old life and resurrection to a new one, so the Lord's Supper is an enacted proclamation of Christ's death and atonement for our sins.
We can expect to partake of the Lord's Supper up until the time of Christ's return.

Q3. (1 Corinthians 11:26) In what way is the Lord's Supper a proclamation? To whom is the proclamation made? Why is this important? What happens to the church when its proclamation shifts to a different central theme?
