My brother passed away in 2002. He was cremated and his remains stayed in a storage (for this purpose) area in a chapel at his church until about late 2004, early 2005 when they were removed to a crematorium in an outdoor garden next to St. Matthews RC church in Charlotte, NC. It is a very peaceful area conducive to prayers and quiet reflection.
Columbarium. We have one at St. Luke's, too.
However, Bishop Jugis has said that no new columbaria are to be built in the Charlotte Diocese at this time. He believes that the Church's preference for burial over cremation should be expressed by their making Catholic cemetery space available, rather than space for cremated remains.
