1 Corinthians 11; 23 -26: 23 For I received from the Lord what I also passed on to you: On the night when He was betrayed, the Lord Jesus took bread, 24 gave thanks, broke it, and said,“This is My body, which is for you. Do this in remembrance of Me.”
25 In the same way, after supper He also took the cup and said, “This cup is the new covenant established by My blood. Do this, as often as you drink it, in remembrance of Me.” 26 For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes.

On the first Lord Supper it was celebrated just before Jesus death on the cross during on Passover week on the first day. Than Jesus took the bread gave thanks and broke it and said “This is My body, which is for you. Do this in remembrance of Me. Took the cup gave thanks and said this is a new covenant established by My blood it is shred for many for the forgiveness of sins. Do this, as often as you drink it, in remembrance of Me.” “
The apostle Paul wrote these words,”So a man should examine himself; in this way he should eat the bread and drink from the cup.” He also wrote, “ Therefore whoever eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord. For this reason many among you are weak and sick, and a number sleep.” According to 1964 CRC Celebration Of The Lord Supper wrote these words, words,”Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. A man ought to examine himself before he eats of the bread and drinks of the cup. For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself. However, this only a caution for those who do believe in the atoning work of Jesus Christ.

To those who believe atoning work they welcome to the Lord Supper, as it stated same doctrine, ”Let all of us, therefore, consider our sin and guilt. God’s anger against sin is so great that he has punished it in his beloved Son with the bitter and shameful death of the cross; and let us examine whether our hearts accordingly are filled with that “godly grief ” that “produces a repentance that leads to salvation.”

Let us also search our hearts to see whether we truly believe in Jesus Christ as our only Savior, and accept God’s gracious promise that for the sake of the passion and death of Christ all our sins are now forgiven and we are clothed with the perfect righteousness of the Son of God. Finally, let us examine our consciences to see whether we resolve sincerely and gratefully to serve Jesus Christ as Lord and to live by his commandment: “You shall love the Lord your God with all your heart, and with all your soul, and with all your mind . . . and . . . Your neighbor as yourself.”
As we thus examine ourselves, let us be assured that God will certainly receive in grace and welcome to the table of his Son all those who repent and walk in faith.
However, the Lord admonishes those who do not believe or have not repented to abstain from the holy supper so as not to eat and drink judgment on themselves.”
As believer in Jesus Christ we’re celebrating the Lord Supper remembering that He sacrifice Himself took our sins and replace it with His righteousness, took His Father wrath, and His Father is satisfied with the payment, and now we’re reconciled with His Father and have access to his heavenly throne. I am strong believing that the Lord Supper should be celebrating weekly as John Calvin is and back it up with scripture. “ And they continued steadfastly in the apostles’ doctrine and fellowship, and in breaking of bread, and in prayers. And upon the first [day] of the week, when the disciples came together to break bread. I also believe confessing your sins regularly. When you sin against your fellow human race , you need to acknowledge before them your sins and seek their forgiveness.
John Stott wrote,” They are given to us we receive them. And as we eat the bread and drink the wine physically, so spiritually by faith we feed on Christ crucified in our hearts. Thus, in both sacraments we are more or less passive, recipient not donors, beneficiaries not benefactors.
