William Wilberforce was born on August 24, 1759. Several years ago, my husband and I enjoyed the movie Amazing Grace so much that we gave everyone in our families a copy of the DVD for Christmas. While it may not have emphasized the connection between Wilberforce's faith in Jesus Christ to his humanitarian efforts, which included child welfare and the end of the slave trade, of slavery, and other ethical and moral issues, like the prevention of cruelty to animals, it made it clear that he was a Christian and a good man.
Wilberforce was an evangelical Anglican, yet his sons were all influenced in one way or another by the Oxford Movement. Three of his sons followed Blessed John Henry Newman and Henry Manning into the Catholic Church (William, Henry, and Robert). The other son, Samuel, was Bishop of Oxford and then of Winchester. Wilberforce at first had opposed Catholic Emancipation but he later supported its passage in 1829, although he was out of office by then.
