He never told us when to have communion either, Reckon why?
There may be a VERY good reason for that, He told us to observe the Passover...
Joh 13:17 If ye know these things, happy are ye if ye do them.
Paul kept the Passover and Days of Unleavened Bread...
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 11:23 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:
Luk 22:19 And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me.
Luk 22:20 Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
Luk 22:21 But, behold,
the hand of him that betrayeth me is with me on the table.
Christ and the disciples were not eating chocolate bunnies and rolling colored eggs this night, they were keeping the Passover.
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.
These are the New Testament Passover symbols that Christ instituted...
Luk 22:15 And he said unto them, With desire I have desired to eat this passover with you before I suffer:
Luk 22:16 For I say unto you, I will not any more eat thereof, until it be fulfilled in the kingdom of God.
Luk 22:17 And he took the cup, and gave thanks, and said, Take this, and divide it among yourselves:
Luk 22:18 For I say unto you, I will not drink of the fruit of the vine, until the kingdom of God shall come.
Luk 22:19 And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me.
Luk 22:20 Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
