A Reformed Church utilizes many statements of philosophy & faith. These include a historic Apostles Creed, Nicene Creed, and Athanasian Creed; the traditional Reformed Belgic Confession, Heidelberg Catechism, and Canons of Dort; and a modern "Our Song of Hope".

Its oldest class action of congregations, a (Collegiate) Reformed Protestant Dutch Church of the City of New York, now called a Collegiate Church Corporation, was founded inside 1628 in New Amsterdam. These are a oldest Protestant church with a continuous ministry - & as well the oldest corporation - within North America. Although a British captured a New Netherlands in 1664, all RCA ministers were however trained in the Netherlands and all services in the Reformed Church remained in the Dutch language until 1764. Dutch language utilise faded therafter until the future wave of Dutch immigration in the mid-1800s, which prompted a irregular revival of it. Many churches left a denomination within 1857 to form a Christian Reformed Church (CRC), and supplementary churches left inside 1882 for the CRC. around the post-Globe War II years a church expanded in Canada, which was the destination of a big class action of Dutch emigre. Between 1949 and 1958 the church opened 120 churches among non-Dutch suburban communities.
