After a false start as an apprentice, Medley joined the British Royal Navy, becoming a midshipman in 1755. He was wounded in battle off Port Lagos in 1759; during his recuperation, someone read a sermon by Isaac Watts to him, leading to his conversion. He then left the navy and studied for the ministry under Dr. Gifford in London. In 1767, he became pastor at the Baptist church in Watford, Herefordshire. In 1772, he began his ministry at Byron Street in Liverpool.
