It was a "lamb" that God commanded as the original blood sacrifice of the first PASS OVER.....just as death passed over the Hebrews when the sacrificial lamb's blood was used to to place a mark on those who were to be protected, the Christian is protected by the Blood of Christ.....the perfect sacrificial lamb of God, "Behold the Lamb of God......(Jesus)" -- John 1:36
One must be covered in the same fashion with blood from the Lamb of God.....aka, Christ Jesus, the Messiah of prophecy.
As pointed out one is born again after symbolically placing the old man to death in water baptism (one must be born again of water and the spirit -- John 3:5) This is where one comes into contact with the Blood of the Lamb.....to defeat death and rise as a new born void of sin. (1 John 3:5-6, Mark 1:4, Romans 6:4)
What was Jesus declaring when holding up the Chalice which represented His blood, and the bread which represented His body? Just as the Hebrews offered annual animal sacrifices to hide their sins from God (who cannot look upon sin)......Jesus is instructing His disciples and all those who would follow His teachings to Commune in remembrance of His teachings after His death until His return. Christians are to commune weekly in communion to remind them they are still covered in the Blood of the Lamb as promised by Christ when He was celebrating the Hebrew Passover (He lived and died as a practicing Jew of the Mosaic Covenant).
As instructed by the Apostles of Christ. The Lord's Supper or as more commonly titled "communion" is explained in detail by the Apostle of Christ. The one verse that does use such a translation as the Lord's Supper in place of communion is found in 1 Cor. 11:20. Paul is scolding and chastising members of the Church at Corinth for treating the Lord's Supper, i.e., Communion as an ordinary meal like they would have in their homes (they were making a party of the church gatherings on the 1st day of the week (sunday). -- 1 Cor. 11:20-34.
In this passage the Apostle explains the meaning of the Lord's Supper. The Bread that was broken represents the Body of Christ that was broken for us in our stead (vs. 23-24). The Cup aka your Chalice symbolizes the New Covenant for which Jesus shed His blood for the many (vs. 25, and Mark 14:24). What was in the cup (Chalice)? Fruit of the Vine (Mark 14:23-25). The Lord's Supper is taken weekly on the 1st day of each week (Acts 20:7)
Christianity is all "spiritualism" not "literalism"..........your spirit, aka your mind that eternal energy that controls this sac of flesh called a body (that will perish as does all things physical) is communing with the Holy Spirit of God every time he/she reads from the pages of the revealed word of God, as ALL SCIPTURE IS INSPIRED OF GOD (2 Tim. 3:16)
