Church of Paulist Fathers, ca. 1910.

The history of the Church of St. Paul the Apostle provides a case study of the birth and growth of a missionary parish in the years immediately before and following the Civil War. The parish had its origins in an 1858 agreement with Archbishop John Hughes, in which the new Paulist Fathers community was given the responsibility for a territory initially extending on the west side of Manhattan from 59th Street to 109th Street. Isaac T. Hecker, C.S.P. (1819-1888), a New York-born Catholic convert of German heritage, was both the first pastor of St. Paul's and the first leader of the Paulists. In 1858, Hecker received Papal authorization to found the first male religious community organized within the Archdiocese of New York and the United States, the Congregation of Missionary Priests of St. Paul the Apostle (better known as the Paulist Fathers). Establishing both a community and a parish required immediate fundraising. The Paulists sought pledges toward the erection of a parish church and community house, with an initial contribution from Archbishop John Hughes, and the largest donation coming from Isaac Hecker's brother George, developer of "Hecker's Self-Rising Flour." The Paulist Fathers acquired land at 59th Street, west of Ninth Avenue, which remains the parish center. As the building rose from its foundations using stone recycled from the old Croton Aqueduct, the Greenwich Elevated Railroad reached Ninth Avenue and 59th Street. In 1876, the north boundary of the parish was reduced from 109th to 75th Street. The Catholic population of the neighborhood increased, until it peaked at some 27,000 in the 1890s. In 1890, artist John Lafarge directed the redecoration of the interior of St. Paul the Apostle. New altars were fashioned from rare Numidian marble, Mexican onyx, and porphyry. Derricks, with their blocks and tackle, were used to lift the altars into position. Harper's noted that the church never closed; work proceeded while "service at St. Paul the apostle never ceases."
In the early 20th century, the Paulist Fathers' Church was known for its music as well as for its preaching. Its choir of men and boys achieved a national reputation when the Paulist Choristers toured widely and performed regularly on the Paulist radio station WLWL. Seats for festival Masses such as the Christmas Eve Midnight Mass were reserved for ticket holders.
