The Reformed Church in America is considered the oldest continuous denomination in the country with roots going back to the establishment of New Amsterdam (New York City) and Fort Orange (Albany) in 1628.  While Dutch in heritage, the RCA now focuses on a multicultural future in the mold of Revelation 7.

The Reformed Church is confessional church directly flowing from the events of the Reformation in 1517. Official creeds and confessions used to guide our faith and life include the Apostles' Creed, Nicene Creed, Heidelberg Catechism, and the recently adopted Belhar Confession. Such creeds and confessions speak of God's movement within the world through Jesus Christ as well as the role of the church to be a community of faithful servants with and for our savior.

The Reformed Church is governed by regional bodies of collected elders and ministers called consistories, classes, regional synods and the yearly general synod. Trinity actively belongs to the North Grand Rapids Classis and is also involved with area ecumenical efforts and initiatives.
