For born again Christians Holy Communion is not optional. It is one of the commandments Jesus gave to His followers.
John 6:48, 53-58
48 “I am the bread of life.”
53 Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you.
54 “Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day.
55 “For My flesh is food indeed, and My blood is drink indeed.
56 “He who eats My flesh and drinks My blood abides in Me, and I in him.
57 “As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me.
58 “This is the bread which came down from heaven–not as your fathers ate the manna, and are dead. He who eats this bread will live forever.” (NKJV)
PURPOSE OF THE SACRAMENT
“And He took bread, gave thanks and broke it, and gave it to them, saying, ‘This is My body which is given for you; do this in remembrance of Me’” (Lk 22:19).
A Remembrance Offering
The Lord instituted Holy Communion as a remembrance offering for what He did on the Cross of Calvary when He said: “It is finished.” The world has substituted that with a ceremony called Christmas to remember His birthday. December 25 is not the birthday of Jesus Christ. Nobody can know the date Christ was born for the Lord has chosen to keep it secret. December 25 is the birthday of Tammuz a pagan deity. Christmas is a heathen ceremony. Nowhere in the Scriptures are Christians required to remember or celebrate the date Jesus was born. God in His infinite wisdom hid the date Christ was born. Jesus was not born on December 25 as some suppose.
Also, Holy Communion is a remembrance of the new covenant sealed with the blood of Jesus on the Cross of Calvary. That is why Jesus urges His followers to take it until the next time He will celebrate it with His saints in the second heaven, in the presence of Satan and his cohorts after the rapture of the church. As a prophet David foresaw that and declared “You prepare a table before me in the presence of my enemies; you anoint my head with oil; my cup runs over.” (Ps 23:5).
A Memorial Offering
It is a re-enactment of the breaking of His body and shedding of His blood. It is important in the humdrum activities of daily life to memorialise Christ’s death and its purpose till He comes. ‘Till He comes’ acknowledges the fact of His resurrection from the dead, ascension and session at the right hand of God in heaven as well as His second coming.
A Testimonial Offering
It is a demonstration of an inward work of the Holy Spirit in the similitude of water baptism; an outward witness of an inward reality, bringing to the fore the need to eat the flesh of Jesus and drink His blood spiritually both in public and in private.
A Confirmatory Offering
It is a confirmation of the fulfilment of Old Testament promise to make a new covenant with the blood. The New Testament church is entered into only by the blood of Jesus (Heb 12:24).
A Proclaiming Offering
It is proclaiming that Jesus is indeed coming back to earth to judge the quick and the dead and showing the Lord’s death till He comes. Proclaiming the Lord’s death means acceptance of the substitutionary death of Jesus, for He did not die for Himself.
A Confessional Offering
It is an announcement and notice to the kingdom of darkness to not touch the anointed of the Lord who bear His mark and do not want to partake of the table of the devil. “Also I say to you, whoever confesses Me before men, him the Son of Man also will confess before the angels of God” (Lk 12:8).
A Judgmental Offering
If we judge ourselves, we shall not be judged. By judging ourselves we avoid being chastised by the Lord. It portrays expectation of the soon return of the Lord to judge the living and the dead.
