The Lord’s Supper, consisting of the elements – bread and the fruit of the vine is the symbol expressing our sharing the divine nature of our Lord Jesus Christ. It is a memorial of His suffering, death and a prophecy of His second coming. Jesus Christ commanded the church to do it in His remembrance. The bible record also shows the early church took this commandment seriously.
