Interchurch

Interchurch is a term used to describe cooperation, dialogue, and joint action between different Christian churches or denominations. It denotes both the process of building relationships across church lines and the concrete programs that arise from such collaboration. The scope includes formal organizations such as interchurch councils and federations as well as informal networks that unite diverse Christian groups for shared purposes.

The modern interchurch or ecumenical dimension broadens past denominational distinctions to emphasize common mission. Its roots are in the 19th and 20th centuries, with increasing formalization in the 20th century. The establishment of international and national bodies aimed at cooperation, dialogue, and service marked a turning point. The World Council of Churches, founded in 1948, is often cited as a landmark development in the broader ecumenical movement, though many interchurch initiatives operate independently of it.

Interchurch activity typically includes joint worship or prayer services, shared social action, disaster relief, development projects, theological dialogue, and advocacy on social issues such as poverty, peace, and justice. Although participating churches maintain their own governance and doctrinal identities, they cooperate on common goals such as humanitarian aid, community service, and environmental stewardship.

In contemporary usage, interchurch activities are sometimes distinguished from broader ecumenical aims or from strictly interdenominational efforts. They can range from local community projects to international networks, reflecting a continuing interest in unity, practical cooperation, and mutual support among Christian communities.
