The Matthew passage compresses the last supper — the event we remember in communion — into three verses. Matthew mentions singing a song… and the Jesus says that the disciples will betray.

Matthew 26:26-35

26While they were eating, Jesus took a loaf of bread, and after blessing it he broke it, gave it to the disciples, and said, “Take, eat; this is my body.” 27Then he took a cup, and after giving thanks he gave it to them, saying, “Drink from it, all of you; 28for this is my blood of the covenant, which is poured out for many for the forgiveness of sins. 29I tell you, I will never again drink of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom.”

30When they had sung the hymn, they went out to the Mount of Olives.

31Then Jesus said to them, “You will all become deserters because of me this night; for it is written, ‘I will strike the shepherd, and the sheep of the flock will be scattered.’

We are fallen. We are inconstant. With the best of intentions at the beginning of the day, by the end we have strayed. It is wrong. It is also very human. We strive, but fail.

And the Gospels record the Apostles failures. And many readers have, sanctimoniously, said they would not have fallen, forgetting that was exactly what the apostles said before they abandoned Jesus.
