I have heard that on the 50th anniversary of the Saint's departure to heaven, they are then canonized and are then allowed to have their names mentioned in the Commemoration of the Saints. Some people told me that their relics are finally exhumed from their shrines and relics are to be given to the churches. But my church has many cylinders with the relics of the saints whom haven't even been canonized by the Holy Synod. Does the Saint have to be canonized in order to have relics distributed in the churches ? And can anyone clarify if there is any truth to the special ceremony on their 50th anniversary ??
