Isaiah 62:8-10 Amplified Bible

8 The Lord has sworn [an oath] by His right hand and by His mighty arm,
“I will never again give your grain as food for your enemies,
Nor will [the invading] foreigners drink your new wine for which you have labored.”
9 But they who have harvested it will eat it and praise the Lord,
And they who have gathered it will drink it [at the feasts celebrated] in the courtyards of My sanctuary.

10 Go through, go through the gates,
Clear the way for the people;
Build up, build up the highway,
Remove the stones, lift up a banner over the peoples.

Here in these passages I find the meaning and source of communion.

It begins with the oath sworn by our Lord.

Psalm 132:11 The Lord swore to David a sure oath from which he will not turn back: “One of the sons of your body I will set on your throne.”

His promise was kept in Jesus. 

Communion: “a having in common (koinos), partnership, fellowship” Strong’s g2842

One of the oldest issues of making a contract was in celebrating a shared meal between the two parties, the breaking of bread together. This oath of the Lord is one that declares He will not covenant with the enemies of Christ.

The next issue is the celebration of the feast. Remember our recent conversation about agape love defined as a love feast.

To eat and drink in the courtyard of His sanctuary requires that those invited to participate in this communal feast, this love feast, must be deemed holy.

Psalm 5:7 But I, through the abundance of your steadfast love, will enter your house. I will bow down toward your holy temple in the fear of you.

1 Peter 1:16 since it is written, “You shall be holy, for I am holy.”

The last issue is the banner, a sign to everyone, of our Lord’s oath to us.

John 6:51 I am the living bread that came down from heaven. If anyone eats of this bread, he will live forever. And the bread that I will give for the life of the world is my flesh.”
