1) Prayer and confession of sins: Jesus said to christians that they need to pray to God, and believe and what He is going to do with Jesus' death in order to be saved.
2)Baptism and Confirmation: Baptism is the public showing of your faith in Jesus, and "rebirths" you. It makes you like Jesus in the aspect of His burial(going under the water) and His Resurrection (coming back up to the surface)
3)This is the Last Supper. Typically eaten in the mass of the church shortly before Easter. This is to remember Jesus' last meal with His diciples and the breaking of the bread and drinking of the wine(His body and blood)
4) This is what all christians are called to do. We are to be "Fishers of Men" and lead others to Christ. We are to be kind, loyal, and caring. We are to put aside ourselves and become more like Christ in our everyday lives. Or at least try to.
