The WCC brings together churches, denominations and church fellowships in more than 110 countries and territories throughout the world, representing over 500 million Christians and including most of the world's Orthodox churches, scores of Anglican, Baptist, Lutheran, Methodist and Reformed churches, as well as many United and Independent churches. While the bulk of the WCC's founding churches were European and North American, today most member churches are in Africa, Asia, the Caribbean, Latin America, the Middle East and the Pacific. There are now 348 member churches.
For its member churches, the WCC is a unique space: one in which they can reflect, speak, act, worship and work together, challenge and support each other, share and debate with each other.
