The passage clearly indicates that churches were consecrated before, and that accordingly the anniversaries of the dedication might now be publicly celebrated._ > _Of course, what the precise form of this consecration was is not entirely clear, but "we find occasional notices of the vigil kept before the consecration, of the translation of the relics, and of the tracing of the Greek and the Latin alphabet on the pavement of the church... Often only the Greek alphabet or the Latin was written twice; and sometimes to the Greek and Latin the Hebrew alphabet was added (Martène, De Antiquis Ecclesiæ Ritibus, II)."
