162. AN INSCRIPTION WITH A POINT

On the comparatively new organ at Ober Ammergau, on a brass plate above the keyboard, is the following Latin inscription:—

QVI CHRISTI LAVDES CANTANT
SANCTÆ PASSIONIS SVÆ VIRTVTE
IN IPSO ET PATRE VNVM SINT

which may be freely rendered—“May those who sing the praises of Christ be, by virtue of His Sacred Passion, one in the Father and in Him.”

These lines contain a hidden point, beyond their obvious interpretation. Can you discover it?
