On December 8, 2020, Bishop Francis Malone of the Diocese of Shreveport declared him to be a Servant of God, opening the diocesan phase of inquiry into a Cause of Beatification and Canonization.
Born in Lanloup, France to Guillame and Claudine Pierre, he entered the Petit Seminaire de Tréguier on 3 August 1845, weeks before his fourteenth birthday.
He joined a student association known as The Congregation of the Most Holy Virgin, a community dedicated to the cultivation of deeper personal piety.
Bishop Augustus Marie Martin recruited him to come to the newly erected Diocese of Natchitoches in Louisiana and Pierre departed the port of Le Havre on 8 October 1854.
[4] Pierre became the first pastor of Holy Trinity Catholic Church (Shreveport, Louisiana) and was serving there when the Yellow Fever Epidemic of 1873 struck the city.
