Book excerpt: A Plain Account of Christian Perfection by John Wesley is about the theory of perfection according to Christian theology. Excerpt: "1. WHAT I purpose in the following pages is, to give a plain and distinct account of the steps by which I was led, during the course of many years, to embrace the doctrine of Christian Perfection. This I owe to the serious part of mankind; those who desire to know all the truth as it is in Jesus. And these only are concerned with questions of this kind. To these I would nakedly declare the thing as it is, endeavoring all along to show, from one period to another, both what I thought, and why I thought so."
