For anyone interested in discussions on “openness” in the past there was an exchange primarily between I.L. Kephart and the Rev. T. Williston in vol. 3 of Wilford’s Microcosm (1883).

Several others also contributed to the discussion. It will take some effort to scroll through the volume to find it all. Kephart was a prominent United Brethren professor and editor of the official UB magazine. He was influenced by McCabe and advanced the “openness” position. The discussion continued in Vols. 4 & 5 but most of it is found in Vol. 3. I don’t think the subsequent volumes are available at Google Books at this time.
