Arthur Ritchie (June 22, 1849 - July 9, 1921) was a prominent American Anglo-Catholic priest, author, and leader.
The parish's current building was completed to Anglo-Catholic specifications in 1902 during Ritchie's tenure, featuring a tabernacle for reservation of the Blessed Sacrament, built-in confessional booths, permanent stoups for holy water, and a de-emphasized pulpit (which was itself removed in 1929).
A prolific author, Ritchie was the editor of the major Anglo-Catholic periodical The Catholic Champion from December 1, 1888, to November 1, 1901.
He was also a founder with his brother Robert of the Clerical Union for the Maintenance and Defense of Catholic Principles.
He was unmarried, and he was buried from St. Ignatius of Antioch at Rockland Cemetery in Sparkill, New York.
