The Feast of the Exaltation of the Holy Cross, celebrated on the 14th September recalls three events:

1. The finding of the True Cross by Saint Helena.
2. The dedication of churches built by Emperor Constantine on the site of the Holy Sepulchre and Mount Calvary.
3. The restoration of the True Cross to Jerusalem in AD 629 by the Byzantine emperor Heraclius, after it had fallen into the hands of the Persian Emperor Chosroes II in the AD 614 Sasanian conquest of Jerusalem.

This Sung Mass is offered by the Venerable David Gunn-Johnson and falls within the Heritage Open Days weekend events at St Michael and All Angels.
