It was good enough for these Gentiles...
1Co 5:6 Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?
1Co 5:7 Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us:
1Co 5:8 Therefore let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth.
1Co 11:20 When ye come together therefore into one place, this is not to eat the Lord's supper.
1Co 11:21 For in eating every one taketh before other his own supper: and one is hungry, and another is drunken.
1Co 11:22 What? have ye not houses to eat and to drink in? or despise ye the church of God, and shame them that have not? What shall I say to you? shall I praise you in this? I praise you not.
1Co 11:23 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:
1Co 11:24 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.
1Co 11:25 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.
1Co 11:26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
Notice this is not about the resurrection? It is about His death in our stead.
1Co 11:27 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.
1Co 11:28 But let a man examine himself, and so let him eat of that bread, and drink of that cup.
1Co 11:29 For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
1Co 11:30 For this cause many are weak and sickly among you, and many sleep.
And Christ said this about the Passover He kept with His disciples after instituting the foot-washing, bread and wine...
Joh 13:4 He riseth from supper, and laid aside his garments; and took a towel, and girded himself.
Joh 13:5 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.
Joh 13:6 Then cometh he to Simon Peter: and Peter saith unto him, Lord, dost thou wash my feet?
Joh 13:7 Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter.
Joh 13:8 Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.
Joh 13:9 Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head.
Joh 13:10 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.
Joh 13:11 For he knew who should betray him; therefore said he, Ye are not all clean.
Joh 13:12 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?
Joh 13:13 Ye call me Master and Lord: and ye say well; for so I am.
Joh 13:14 If I then, your Lord and Master, have washed your feet; ye also ought to wash one another's feet.
Joh 13:15 For I have given you an example, that ye should do as I have done to you.
An example that they should do? Why, He was crucified the very next day, os apparently that did not put an end to this.
Joh 13:16 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.
Joh 13:17 If ye know these things, happy are ye if ye do them.
I weep for those who are so blinded they can't even see the simple Passover service Christ instituted for His.
