I want to know the answer to the following question:
What types of churches have had rapidly declining memberships?
All the background I'm provided with is that "One, but not the only expression of the ecumenical movement, has been the move to form united churches, such as the Church of South India, the Church of North India, the US-based United Church of Christ, the United Church of Canada, the Uniting Church in Australia and the United Church of Christ in the Philippines which have rapidly declining memberships.". Is that enough to answer the question?
Answer: yes
