Inconsequential? Read a history book!! The Reformers NEVER thought their differences were inconsequential!!!
Donald Bloesch
Well-known and respected evangelical theologian Bloesch excoriates the divisions of Protestantism (which are characteristic of its whole history), in a section entitled The Scandal of Disunity:
The disunity of the Christian church today . . . is indeed deplorable. But even more scandalous is the disunity that plagues the evangelical family . . . Christian disunity is a contradiction of Christ's prayer that his people be one (John 17:20-23). It also conflicts with Paul's declaration that there is only one body and one Spirit . . . one Lord, one faith, one baptism (Eph 4:4-5). Disunity on theological and even sociological grounds betrays an appalling ignorance of the nature of the church. Indeed the classical marks of the church of Jesus Christ are oneness, holiness, apostolicity and catholicity. The last term denotes universal outreach and continuity with the tradition of the whole church. It is incontestable that the church, and especially the evangelical church, has lost much of its credibility on the mission field because of the bitter infighting between missionary boards and churches.
