Phillip Jensen is an Australian cleric of the Anglican Diocese of Sydney and the former Dean of St Andrew's Cathedral. He is the brother of Peter Jensen, the former Anglican Archbishop of Sydney.
Jensen spent the early years of his life living at Bellevue Hill, a suburb in the eastern suburbs of Sydney. His first public statement of faith came at a Billy Graham crusade in 1959. He married his wife Helen in 1969.
Jensen studied theology at Moore Theological College from 1967 to 1970 and won the Hey Sharp prize for coming first in the Licenciate of Theology (ThL), the standard course of study at that time. In the years just after his graduation from Moore College, Jensen worked at St Matthew's Manly and with John Chapman at the Department of Evangelism (now known as Evangelism and New Churches). Jensen became Anglican chaplain to the University of New South Wales (UNSW) in 1975 and Rector of St Matthias' Centennial Park in 1977.
Jensen based his university ministry around expository preaching and "walk-up evangelism". The result was a large number of conversions, large student gatherings at UNSW and the growth of St Matthias' Church from a group of 20–30 in 1977 to well over 1000 by the mid 1990s.
Jensen's work at UNSW included the creation of the Ministry Training Strategy (MTS) which trained young men and women in practical ministry skills, preparing them for church ministry, ordained or otherwise. He also founded the Australian Christian publishing house Matthias Media to allow the publication of Christian literature by Australian authors. From 1974 to 1991 Jensen led the reinvigoration of the Katoomba Christian Convention. He also authored the Two Ways To Live gospel tract and founded The Briefing. He has also been involved in the establishment of some independent evangelical churches and facilitated links between them and the Anglican Diocese of Sydney.
