Why/how do churches do communion?

(Message recorded 10-07-2012) 1 Corinthians 11:26 (NLT) For every time you eat this bread and drink this cup, you are announcing the Lord’s death until he comes again. BIG IDEA: Communion is an experience that weaves us into the PAST, PRESENT and FUTURE of Christ. Greek Word: εὐχαριστέω (eucharisteō) to recognize an undeserved gift and give thanks. • Sacrament or Ordinance. • Literal or Symbolic. • Formal or Informal. Check your readiness for communion: 1. Take a minute to reflect on the selfish and sinful attitudes that tend to guide your actions. 2. Are you sorry for rebelling against God by pursuing your selfish way instead of His righteous way? 3. Do you recognize that God loves you so much that He sent His only Son to take on the full penalty for your selfishness and sins—past, present and future? By faith, do you accept His gracious gift of forgiveness? 4. Do you trust that as Christ died for your sins, He also rose from the dead to give you a new, eternal life? 5. Do you call Jesus your Savior who saves you from the eternal penalty of sin, and also call Jesus the Lord of your life who leads you into righteousness? If you honestly answered “yes” to the questions above, participate in communion—to remember Christ’s past sacrifice, to celebrate His righteousness covering you today, and to look forward to His future kingdom. If you’re not sure, use this time to silently express your doubts to God, and open your heart to His lead.
