Jesus gives his disciples a new commandment: love one another as I have loved you. The message of love is not a new one: love of God and of neighbour were the two great commandments of the Old Testament. But Jesus calls on his disciples to love one another ‘as I have loved you:’ and he gives them this commandment at the Last Supper. He has just shown them an example of loving service by washing their feet, and the next day, he will give his life on the Cross. To love one another as Christ has loved us is to give ourselves without reserve; there is no greater love than to lay down one’s life. And, by his life and his teaching, Jesus shows us that love of neighbour includes not only those who are like us, but the whole human race. He sets no limits to his love, and he calls his disciples to do the same. It is by our love for one another that we will be known as disciples of Christ. What a challenge.
