A one-of-a-kind work written from the Reformed perspective.

The author notes,

"I deem it right to state that I attribute to the Brethren no doctrines they do not hold, that I give ample quotations from their works, fairly representing all their opinions, and that I confine myself strictly to the business of refuting their arguments from Scripture. I have followed Hodge, the American divine, closely, almost verbally, in my treatment of the true doctrine of the Church and its unity."
