A dedicated high churchman, but with evangelical spirit, Ravenscroft was known for his booming voice and strident promotion of the Episcopal Church, including his own story of knowing sin and being saved by God's grace. He attended several General Conventions, as well as every diocesan convention. His missionary journeys beginning in 1818 took him over the Cumberland Gap into Tennessee and Kentucky. He confirmed Tennessee's future first bishop, James Hervey Otey, during his 1824 visitation. During his last such trip, on July 1, 1829, he chaired the organizational convention of what eventually became the Episcopal Diocese of Tennessee. Travel or other circumstances, however, took a toll, and in 1828 he gave up the rectorship in Raleigh in favor of the smaller St. John's Church in Williamsboro where his protege Rev. Green lived.
