But the chief contention with us is not a rubric, or a series of canons, or even the parochial episcopacy which we know to be scriptural, but the scriptural doctrines of the gospel. We aim at a careful discrimination between the essential and the non-essential. We propose orthodoxy of faith as the object of supreme regard, and relegate to the rear a punctilious churchmanship. . . . Honest investigation is the honorable way to exchange party for party, and sect for sect. I want all restless Presbyterians to examine first, and venture upon no change without study and prayer. And let them be firmly resolved to serve God for life in a Christian association which they conscientiously regard as the most faithful to the word of God (J. A. Waddell, Letters to a Young Presbyterian, 102).
