A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.@John 13:34

Beneath the shadow of the cross
As earthly hopes remove,
His new commandment Jesus gives,
His blessèd word of love.

O bond of union, strong and deep!
O bond of perfect peace!
Not even the lifted cross can harm,
If we but hold to this.

Then, Jesus, be Thy Spirit ours!
And swift our feet shall move
To deeds of pure self-sacrifice,
And the sweet tasks of love.
