I want to know the answer to the following question:
When was the Massey conference held?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: yes
