What does the title “Sanctified Unity Ecclesiology” mean or stand for?

"Sanctified Unity Ecclesiology" was a phrase used in a couple of comments on Stack about seven years ago. One person asked what the O.P. meant by it. The response was that it is a name given for the pursuit of attaining Christian unity, while seeking to harmonize divergent views. In the OPs question there were answers with premillennial and dispensational views (which has nothing to do with this question here). The OP was happy to consider both them and amillennial and non-dispensational views. Sanctified Unity Ecclesiology was said to be one of “various tools of interpretation for understanding the scriptures.” Searching on-line only brought up links and books on the doctrine of ecclesiology and the doctrine of sanctification. I found nothing about “the pursuit of attaining Christian unity while seeking to harmonise divergent views.” Can anyone explain what this, as a title, has sprung from, and how it is used as a tool to interpret the Bible, plus whether there are any particular denominations involved in this? There is a p.d.f. with this link from a newsletter giving a review of a book on Early Holiness-Pentecostalism 1880-1909 by Joseph L. Thomas, "Perfect Harmony". The review gives that very phrase. https://urbanatheologicalseminary.org/wp-content/uploads/2023/09/201409-The-Flame.pdf Thanks to Grateful Disciple for providing this.
