On this date, March 19. 1730, Philip Doddridge was ordained to the ministry. If you are not familiar with Doddridge, he wrote the book The Rise and Progress of Religion in the Soul that was essential in the conversion of William Wilberforce to Christianity.
Wilberforce, one of my heroes, was one of the main forces behind the Slave Trade Act that abolished slavery in English territories in 1807. If you have never read about Wilberforce, I highly recommend Amazing Grace by Eric Metaxes. One of the best biographies on Wilberforce that I have ever read.
