We celebrate the Lord's Supper every Sunday, which was a practice in the New Testament (Acts 20:7). All believers in Jesus are welcome to participate by coming to one of the tables to receive the emblems.  We normally partake in unison.  The bread and juice are in 2 cups: bread on the bottom, juice on the top. We do this to remember the sacrifice of Jesus, to welcome His presence among His people and to look forward to His return.
