John Newton: From Slave Trader to Abolitionist

John Newton (4 August 1725 – 21 December 1807) was an English evangelical Anglican cleric and slavery abolitionist. He authored the hymns “Amazing Grace” and “Glorious Things of Thee Are Spoken,” and lived to witness the British Empire’s abolition of the African slave trade in 1807, just months before his death.

Early Life and Education

Newton was born in Wapping, London, on 4 August 1725, the son of John Newton the Elder, a shipmaster in Mediterranean service, and Elizabeth (née Scatliff), daughter of an instrument maker. His mother, raised as a Nonconformist, died of tuberculosis in July 1732 when Newton was six. He attended boarding school for two years before moving to Aveley in Essex to live with his father’s new wife.

At age 11, Newton went to sea with his father and sailed six voyages before his father retired in 1742. His father then arranged for him to work at a sugarcane plantation in Jamaica, but Newton instead signed on with a merchant ship bound for the Mediterranean.

Career and Achievements

In 1743, Newton was pressed into the Royal Navy and became a midshipman aboard HMS Harwich. After attempting to desert and receiving a flogging, he was reduced to common seaman. While the ship sailed toward India, he transferred to Pegasus, a slave ship bound for West Africa engaged in the triangular trade. In 1745, Newton traded to a slaver and was taken to the coast of Sierra Leone, where he worked as a servant.

Early in 1748, a sea captain hired by Newton’s father found and rescued him, returning him to England aboard the merchant ship Greyhound. Newton then obtained a position as first mate aboard the slave ship Brownlow and made three voyages as captain of the Duke of Argyle (1750) and African (1752–53 and 1753–54). A severe stroke in 1754 ended his seafaring, though he continued to invest in slaving operations.

In 1755, Newton was appointed tide surveyor of the Port of Liverpool. He studied Greek, Hebrew, and Syriac in his spare time and was ordained as a Church of England cleric, serving as parish priest at Olney, Buckinghamshire, for two decades. After moving to the City of London as rector of St Mary Woolnoth Church, he contributed to the Committee for the Abolition of the Slave Trade, formed in 1787, and wrote “Thoughts Upon the African Slave Trade.”

Notable Events and Milestones

On 21 March 1748, during his return voyage aboard the Greyhound, Newton experienced a Christian conversion. Awakening to find the ship caught in a severe storm off County Donegal, Ireland, and about to sink, he prayed for God’s mercy. The storm subsided, and after four weeks at sea, the ship reached port in Lough Swilly. Newton marked this date as an anniversary for the rest of his life. By the time he reached Great Britain, he had accepted Christian doctrine, though he later reflected in 1764 that his true conversion came considerably later.

On 12 February 1750, Newton married his childhood sweetheart, Mary Catlett, at St. Margaret’s Church, Rochester. He adopted his two orphaned nieces, Elizabeth Cunningham and Eliza Catlett, from the Catlett side of the family.
