When it comes to communion, we believe that Jesus Christ is the host, the One who invites each of us to the table. You are invited to share in the Lord's Supper whether you are a member of our church, another church, or not a member of any church—anyone who wants to get closer to Jesus, to have Jesus be more Lord of their lives than when they came.
What about children? That's up to parents. The rule of thumb is that children are welcome to have communion when they are old enough to understand what it means. Some parents encourage their children to have communion as young as they are able. Other parents ask their children to wait until they are baptized/confirmed. Parents make the call.
