1n 1867, Fr. Charles Menard, the founding Pastor of St. Joseph Church originally located on Highway 1, went to Rome to request a relic that he could bring back to Thibodaux for strengthening the faith of and catechizing the local people. Of the two relics offered him, Fr. Menard chose Saint Valerie, Virgin and Martyr. The relic was placed in the arm of a wax effigy resembling a young girl depicting St. Valerie. She was encased in a glass display box called a brier, gilded and decorated with copper, and made in the Netherlands. The crate containing the brier was shipped to the Port of Orleans in early 1868.
The effigy of St. Valerie arrived from across the Atlantic and was immediately transported to Thibodaux via Bayou Lafourche onboard the steamer Nina Simmes. When it arrived in Thibodaux on April 18, 1868, the brier was hoisted on a fire truck and taken to the Church of St. Joseph accompanied by approximately 4,000 people.
Little is known about the real identity of St. Valerie. However, the local people, especially the youth, grew very fond of her and considered her the patroness against natural calamities.
On May 26, 1916, fire broke out in the sacristy of the old St. Joseph Church located on Highway 1. The fire quickly engulfed the church and local people desperately tried to save what they could. Weighing almost 500 pounds, the brier containing the effigy and relic of St. Valerie was one of a few items saved by responding firemen. The firemen brought the brier to the Mount Carmel Convent Chapel a few blocks away, where it stayed until the new church was built. On April 28, 1940, the brier of St. Valerie was ceremoniously transferred aboard a fire truck from Mount Carmel Convent to its current location in St. Joseph Church.
From her arrival in 1868, surviving the church fire in 1916, and her transfer to the new church, St. Valerie has been associated with the firemen of Thibodaux. For 200 years, St. Valerie has been protecting Thibodaux from major disasters and natural calamities. Her umbrella of protection extends to the firefighters and their families, ancestors of those firemen who first welcomed her on her arrival, saved her from the burning church, transported her to her new home, and continue to honor her with an annual procession on the yearly anniversary of her arrival.
