Query: The Massey conference eventually led to developing what seminars?
Context: In the United Kingdom, Colin Urquhart, Michael Harper, David Watson and others were in the vanguard of similar developments. The Massey conference in New Zealand, 1964 was attended by several Anglicans, including the Rev. Ray Muller, who went on to invite Bennett to New Zealand in 1966, and played a leading role in developing and promoting the Life in the Spirit seminars. Other Charismatic movement leaders in New Zealand include Bill Subritzky.
