Glenn was a school teacher prior to his theological study at Westminster Theological Seminary and Moore Theological College.
After two years in parish ministry at St Stephen’s Willoughby, Glenn was invited to join the faculty of Moore College as a lecturer in Old Testament. At the end of 1985 he took a two-year study leave in England where he gained his PhD from Sheffield University. Glenn returned from overseas in 1988 to take up a position as a lecturer in New Testament. In the following year he also became the Registrar of the College, holding both positions until his resignation in 1995, when he was appointed as rector of St Luke’s Miranda. Glenn left Miranda after being consecrated bishop in December 2001. He was the Bishop of North Sydney for more than ten years, before being overwhelmingly elected Archbishop in 2013.
Glenn is married to Dianne and they have two married daughters and three grandchildren
