The Catholic or Eastern Orthdox Churches are creedal; so, as I understand it, is the Anglican/Episcopal Church. These churches accept the historic Christian Creeds as binding definitions of Christian doctrines. Although the Anglicans have 39 Articles of Faith, these Articles are not strictly binding on Anglicans as a test of orthodox Anglican belief.
Lutherans, Presbyterians, some Reformed Churches are confessional: they have denominational confessions (the Augsburg Confession, the Westminster Confession) which at least in theory are binding on their members.
I only heard this distinction a few days ago in another thread so hopefully I have parsed it correctly. If not someone will correct me.
