1 Corinthians 11:23-29 For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the same night in which he was betrayed took bread: 24 And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. 25 After the same manner also he took the cup, when he had supped, saying, This cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me. 26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come. 27 Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. 28 But let a man examine himself, and so let him eat of that bread, and drink of that cup. 29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
It is important to be sure that we are ready to partake of communion. While we do show the Lord's death til He comes, we ought to be sure that we are ready to partake of communion. We are admonished to examine ourselves. All sins prior to communion should be confessed to God. All wrongs we have done to our brethren should be righted. We are not to eat and drink unworthily, of so great a service. Because many people do do this unworthily...
1 Corinthians 11:30-32 For this cause many are weak and sickly among you, and many sleep. 31 For if we would judge ourselves, we should not be judged. 32 But when we are judged, we are chastened of the Lord, that we should not be condemned with the world.
We ought to be prepared for communion. Now, part of the preparation of communion is missing from most of the churches in the world. It was what Jesus instituted to happen before communion was to take place. This is the washing of each others feet.
John 13:1-17 Now before the feast of the passover, when Jesus knew that his hour was come that he should depart out of this world unto the Father, having loved his own which were in the world, he loved them unto the end. 2 And supper being ended, the devil having now put into the heart of Judas Iscariot, Simon's son, to betray him; 3 Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God; 4 He riseth from supper, and laid aside his garments; and took a towel, and girded himself. 5 After that he poureth water into a bason, and began to wash the disciples' feet, and to wipe them with the towel wherewith he was girded. 6 Then cometh he to Simon Peter: and Peter saith unto him, Lord, dost thou wash my feet? 7 Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter. 8 Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me. 9 Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head. 10 Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all. 11 For he knew who should betray him; therefore said he, Ye are not all clean. 12 So after he had washed their feet, and had taken his garments, and was set down again, he said unto them, Know ye what I have done to you? 13 Ye call me Master and Lord: and ye say well; for so I am. 14 If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet. 15 For I have given you an example, that ye should do as I have done to you. 16 Verily, verily, I say unto you, The servant is not greater than his lord; neither he that is sent greater than he that sent him. 17 If ye know these things, happy are ye if ye do them.
After the washing of the feet, they were made "clean". The washing was a type of higher cleansing that Jesus was doing unto the disciples. Not even the disciples were ready to partake in communion at this point. They would not be ready until their hearts had been washed clean from all alienation, all animosity towards one another. Their hearts had to be changed about one another, and this is brought about during the ordinance of foot washing.
This ordinance of humility established by Jesus is missing from most churches. We are to stoop down, and wash each others feet, just before communion. Striving for the highest place has no place among the Christian heart. We are to humble ourselves, and become servants of all. We are to be selfless, and not selfish.
