The Catholic Church has been divided some centuries ago in three main different streams. One of them is the Protestants stream that has gained much popularity since then.
If you’d like to have information about it, you should check out this site then. Prca.org is the unofficial site for the Protestant Reformed Churches in America. There you will find lots of data about their origins and main beliefs. On the site there are diverse links, like: history and government, practices, institutions and publications, liturgy, church order, declaration of principles, etc. In addition, there is a link containing a list of all protestant reformed churches. Furthermore, there is some literature available, both online and in print. If you wanted to read the salmons, they are available in audio format. The site also includes catechism books, pamphlets and articles, theological school, their mission, etc. If you’d like to know what’s going on now, check out their views and news.
