Reformed Churches began through the efforts of reformers within the Roman Catholic Church in various areas of mainland Europe during the 16th century Protestant Reformation.  The theology of John Calvin helped to coalesce the movement and differentiate it from Lutheranism.  Reformed churches were state churches in various areas of western Europe and the movement spread to the British Isles, where the Church of Scotland became the parent church of Presbyterians.

In the U.S., various groups formed around national groupings and split and merged to form various groupings of Reformed Churches, Presbyterian Churches, and Congregational Churches (many of which are now part of the United Church of Christ). 

Many Reformed Churches in the U.S. have extensive disabilities ministries and resources.  Explore these links to learn more.
