Today there are over a dozen Presbyterian or Reformed denominations in the United States. The PCA (Presbyterian Church in America) began in December of 1973 in Alabama. It shares ties with many other Christian denominations that trace their heritage to the 16th century Protestant Reformation in Continental Europe and the British Isles. Presbyterian and Reformed churches and denominations now exist around the globe in many cultures and languages. They seek to guard and promote the truths of the historic Christian faith (as expressed in the Apostles' Creed and Nicene Creed) and practice.
