A relic is a remnant of a saint, venerated by Catholics as a way to bring one closer to the saint. In most cases, these relics are a part of the saint’s body; items belonging to saints and pieces of cloth pressed against a saint’s bones are also considered relics. Relics are usually contained in cases called thecas and reliquaries; these cases can be quite ornate, or they can be small enough to slip into a pocket.
The majority of Saints Peter and Paul’s collection is housed within special cabinets in the sacristy (shown below), which is displayed in front of the Marian altar each year in commemoration of All Saints Day. Others can be found year-round in the Church or St. Francis of Assisi Chapel.
