Jesus instituted the ordinances of water baptism and the Lord's Supper, both of which are to be observed by His followers until He returns (Matthew 28:19-20; 1 Corinthians 11:23-26).
Water Baptism: The Scripture teaches that all who repent and believe in Jesus Christ are to be baptized by immersion (Matthew 28:19). Baptism is a public profession of faith in Christ. It is symbolic of Jesus Christ's death, burial and resurrection. It also declares to the world that we have died to sin and have been raised with Christ to walk in newness of life (Romans 6:4).
Communion: The Lord's table consists of two elements, the bread and the cup. These elements symbolize the body and blood of Jesus Christ (Matthew 26:26-28). Communion is a memorial of Christ's sufferings on the cross, a celebration of our salvation (1 Corinthians 11:24-25) and His promised return (Matthew 26:29; 1 Corinthians 11:26). Participation is for every follower of Jesus Christ, a right they have and should exercise only after solemn self-examination
(1 Corinthians 11:27-29).
