Some Thoughts by John Wesley on the Sufficiency of Scripture

I have been reading through John Wesley's various writings about the Church of Rome.  In his Popery Calmly Considered, Wesley makes the following comments concerning the "Sufficiency of Scripture":

St. Paul says, "3.  All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be perfect, thoroughly furnished unto all good works."

The Scripture, therefore, being delivered by men divinely inspired, is a rule sufficient to itself: So it neither needs, nor is capable of, any farther addition.

. . . 6. (3.) In all cases, the Church is to be judged by the Scripture, not the Scripture by the Church.  And Scripture is the best expounder of Scripture.  The best way, therefore, to understand it, is carefully to compare Scripture with Scripture, and thereby learn the true meaning of it.
