Jesus came and spoke to them, saying, "All authority has been given to Me in heaven  and on earth.  JESUS' said  as his last command was for us to go and make disciples of all nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all things that I have commanded you;

                                                                                                                 Matthew 28:18-20a

The Lord's Supper

  "And as they were eating, Jesus took bread, blessed it and broke it, and gave it to them and said, "Take, eat, this is my body". And then He took the cup, and when He had given thanks, He gave it to them, and they all drank from it. And He said to them, "This is my Blood of the new covenant which was shed for many. Assuredly, I say to you, I will no longer drink of the fruit of the vine until that day when I drink it new in the kingdom of God." (Mark 14:22-25)

What is the Lord's Supper?

There is a paradox here. The feast, as it was celebrated in the Bible, was always eaten with two simple elements, bread and the fruit of the vine. The Lord has chosen two common and ordinary elements to remind us whenever we eat them, of His sacrifice and love for us. While these elements become especially meaningful at the time of communion, they are also there to remind us of this love at every meal of the day. The paradox is, that though the elements are only natural food, the Lord has caused us to think of them as representing His Body  and Blood. We, who are saved, who are covered by the Blood of the Lamb and who are part of the Body of Christ, are instructed at this time to judge ourselves rightly so that we will not be judged (I Corinthians 11:31). Thus, we are provided a special time for repentance.
