Owen was an independent, not a congregationalist. He held to a non-binding form of inter-church association, and that the locval Church was ruled by Teaching and Ruling Elders.

Congregationalism is the view that the "root court" of the Church is the congregational meeting. Hence, ordination, excommunication, reception of members, etc. all done by the "gathered Church" in a congregational meeting. It is often called the "New England Way" from the history of the congregational churches of New England. There are a few historical books by Williston Walker, himself a congregationalist, (but theologically liberal) on Congregationalism.

History of the Congregational Churches in the US

Also, The Congregational Way, by Arthur Rouner is a modern resource on congregationalism.

Our best marks can contribute nothing to our justification, ...that is proper to faith. Faith cannot lodge in the soul alone, and without other graces; yet faith alone justifies before God.--G. Gillespie
