The Rev. Dennis Schmidt of the Ste. Genevieve Catholic Church in Ste. Genevieve said the relics were found in a zip-locked baggie after the 6 a.m. mass Monday, the St. Louis Post-Dispatch reported Tuesday.
Schmidt said the items, which were taken around Christmas, were returned with a note apologizing for the thefts and asking forgiveness.
The pastor said the thief has been forgiven, but the culprit's identity and motive for the theft remain a mystery.
Lt. Jasen Crump of the Ste. Genevieve Police Department said the case is not being investigated at Schmidt's request.
