John Charles Chapman (23 July 1930 – 16 November 2012), affectionately known as "Chappo", was an Australian preacher, Bible teacher and evangelist[1][2] associated with the Sydney Anglican diocese.
He wrote several books, including A Fresh Start; Know and Tell the Gospel; Setting Hearts on Fire, A Sinner's Guide to Holiness; and Making the Most of the Rest of Your Life, all published by Matthias Media.
This is where he met Preston Walker, Aborigines Welfare District Officer and member of the Moree Methodist Church who later joined the British and Foreign Bible Society.
For 25 years he was the Director of the Anglican Department of Evangelism in Sydney, after beginning his career as a school teacher prior to theological training.
In his retirement he continued to teach at Bible colleges, to speak at conventions[3] around the world and to find time for the occasional game of tennis and golf.
