This chapter seeks to enhance Adventist remnant ecclesiology by exploring the possibility of developing an Adventist version of communio ecclesiology. It outlines what the various mainstream Christian communio ecclesiologies hold in common, in the expectation that this material, with appropriate adjustments, might contribute to an ecclesiology that is genuinely Adventist. The author beliefs that Adventists, too, can accept the prevailing contemporary consensus that the ‘the church is the communio of the faithful’ as a formal theological principle, while, like other Christians, making additional specifications in line with their own distinctive theological heritage and priorities. The elements of overlap and difference here open up the possibility of dialogue between Adventists and other Christians on ecclesiological matters. Since this has not been the usual route taken by Adventists thus far, this chapter provides the theological grounds for highlighting this particular concept of koinonia or communio, as well as some preliminary explanation of how this proposal might work.
