For I received from the Lord what I also handed on to you, that the Lord Jesus on the night when he was betrayed took a loaf of bread, and when he had given thanks, he broke it and said, “This is my body that is for you. Do this in remembrance of me.” In the same way he took the cup also, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes. Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be answerable for the body and blood of the Lord. Examine yourselves, and only then eat of the bread and drink of the cup. For all who eat and drink without discerning the body, eat and drink judgment against themselves. (1 Corinthians 11:23-29, NRSV)
Here we have the words of institution most of us use in worship service for celebration of the Lord’s Supper. No, the words don’t come out of a gospel, but an epistle from Paul to the Corinthians. He is telling them what he heard happened, and are the words we still use today.
Eat this bread and drink this cup, they are my body and blood, do this as often as you will in remembrance of me.
But what is an unworthy manner? And how does one examine oneself?
And how does one examine oneself?
And whose body are we discerning?
You can eat and drink judgment on yourself. You can eat and drink salvation on yourself.
How do we know for sure?
Remember what this meal is. And who this meal is. And what He has done for you, broken and poured out for the many.
In that we can then trust in the promises of God and hold fast to His grace.
