NOTES for Joh 13:21-38
Jesus has gathered His disciples for the final meal, the meal of the covenant. He gives them a new law unlike the old one. His commandment concerns love within His community. It is so easy, after all, to love those who share your beliefs, your brothers...
But the Lord tells them that one of them is a traitor. His commandment now becomes almost impossible to fulfill: how can they love one another if any one of them may suddenly prove to be an enemy? Each tries to distance himself from the dreadful stigma of traitor, but Jesus stops them. He predicts that they will all prove unfaithful—and very soon, before morning.
The disciples, and after them all believers, are not divided into good and bad, faithful and unfaithful. They are united by one human weakness and one incomprehensible commandment: to love one another without trying to guess who will prove to be an enemy, and to imitate the love of the Teacher, who loves them unconditionally.
