Born John Crowley on August 12, 1860 in Millstreet, Cork, Ireland he came to the United States as a young boy. His family settled in Boston. In 1880 he went to the Passionist novitiate in Pittsburgh, Pennsylvania and professed his vows on June 21, 1881 receiving the religious name Celestine. While studying theology he was diagnosed with tuberculosis and in order to improve his health his superiors moved him from one monastery to another. When his health did not improve the superiors told him, he was in Cincinnati, Ohio at the time, to prepare for diaconate and priesthood. Thus, he would have the opportunity to say the Mass prior to his death. He received these offices of the church on August 7 and August 10, 1887, respectively in the monastery chapel at Cincinnati from Archbishop William E. Elder. After this Father Crowley was sent to Pittsburgh where it was thought the climate was beneficial. Fortunately he was able to live for seven more years and was active more as a confessor than a preacher.
