Christianity
The other way was creating unions for different churches to join together. Congregationalist, Methodist, and Presbyterian churches joined together in 1925 to form the United Church of Canada, and in 1977 to form the Uniting Church in Australia. The Church of South India was formed in 1947 by the union of Anglican, Methodist, Congregationalist, Presbyterian, and Reformed churches. And other such formations have been done by different Christian groups throughout the years.
