The dedication of the Church of the Holy Sepulchre in Jerusalem in 335, was performed with remarkable magnificence. After the Synod of the Eusebians at Tyre in this year, many bishops at the invitation of the imperial representative proceeded to Jerusalem, for the great basilica which Constantine had commenced to build on Mount Calvary was now finished. The dedication took place on the 14th September, the day on which the Empress Helena had found the Holy Cross, and which, as the Gallic Pilgrim states, was observed later as an annual festival. Two anniversaries fell, in this case, on the same day and consequently we are unable to conclude that the anniversary of a church’s dedication was at this time already celebrated as a regular thing. It became customary to do so, however, shortly afterwards both in the East and in the West.[433] To the same period belongs the consecration of the so-called Golden Basilica at Antioch, also commenced by Constantine but completed under Constantius in 341. On this occasion also a Synod was held.[434] Unfortunately nothing definite regarding the ceremonies employed at the dedication of a Church can be gathered from Eusebius’ wordy description. He says: “The bishops performed the divine service, and the priests fulfilled their functions, and very magnificent were the ecclesiastical ceremonies. One heard the psalms and the other hymns which come from God, and saw the mystic rites of the service performed; the mystical symbols of the saving Passion were there also. Moreover each of the bishops present delivered a festal address and strove to the best of his ability to promote the festivity.” In the West, even in the fourth century, special ceremonies of dedication were in use, and Ambrose mentions them as generally observed, but the particulars of which they were composed, we cannot now ascertain. However, one of the ceremonies was the placing of relics of the martyrs in the new church, if there were not some there already. In an unconsecrated church there could be no performance of divine service.[435]
