[Jervis] Zimmerman paints a compelling portrait of a hard-working but combative parish priest, quick to take offense, and often at the storm center of controversy. Prescott was subjected to four successive heresy trials in Massachusetts between 1850 and 1852. Again, he was put on trial in Pennsylvania for his ritual practices at St. Clement’s in 1880. At the same time, his relations with Fr. Benson, superior of the SSJE, deteriorated; Benson secured Prescott’s resignation from St. Clement’s in 1880 and released him from his life vows in 1882. Prescott served a variety of parishes in his 53 years of ordained ministry, but often stayed no more than two or three years in one place. His longest tenure was as rector of the African-American parish of St. Luke in New Haven, where he served seven years until his retirement in 1900.
Always professing his loyalty to the Episcopal Church, in times of controversy Prescott also insisted on his rights according to the canons. At least twice he resigned as rector because of what he saw as vestry violations of his canonical prerogatives. When bishops tried to suppress his ritual practices, he argued that such practices were nowhere forbidden by the church’s formularies and that his duty was to defend his parish’s rights against infringement by low-church bishops, who tended to argue that what was not explicitly authorized was forbidden. In other words, Prescott consistently resisted rule by the personal whim of those in positions of ecclesiastical authority. Tellingly, his fundamental disagreement with Benson arose from the latter’s refusal to provide a written constitution for the SSJE despite earlier promises to do so.
