Will you sing it with unchanged faces?

THOMAS CRANMER [writing]:
Lift up your hearts.
THE SINGERS:
We lift them up unto the Lord.
CRANMER [writing]:
Let us give thanks unto our Lord God.
THE SINGERS:
It is meet and right so to do.
CRANMER [writing]:
It is very meet, right, and our bounden duty, that we should at all times and in all places, give thanks.
THE SKELETON:
Ah how the sweet words ring their beauty:
It is meet, right, and our bounden duty.
But will you sing it with unchanged faces
when God shall change the times and the places?
[from Charles Williams, "Thomas Cranmer of Canterbury"]
