Another place where you may have noticed a difference between churches of Christ and other religious groups is in the Lord's Supper.
This memorial supper was inaugurated by Jesus on the night of his betrayal (Matthew 26:26-28). It is observed by Christians in memory of the Lord's death (1 Corinthians 11:24,25). The emblems - unleavened bread and fruit of the vine - symbolize the body and blood of Jesus (1 Corinthians 10:16).
Churches of Christ are different from many in that we observe the Lord's Supper on the first day of every week. Again, our reason centers in our determination to follow the teaching of the New Testament. It says, describing the practice of the first-century church, "And upon the first day of the week...the disciples came together to break bread..." (Acts 20:7).
Some have objected that the text does not specify the first day of every week. This is true - just as the command to observe the Sabbath did not specify every Sabbath. The command was simply, "remember the Sabbath". Its seems to us that by the same reasoning "the first day of the week" means the first day of every week.
Again, we know from such respected historians as Neander and Eusebius that Christians in those early centuries took the Lord's Supper every Sunday.
