"Several times here I have expressed concern that some Calvinists are attempting to take over churches by stealth. I frequently hear from church members (mostly Baptists but occasionally also Pentecostals and other evangelicals) that their new pastor turned out to be a five point Calvinist without their knowing that when he was called. They only contact me about this when the new pastor attempts to impose Calvinism on the congregation—for example by insisting that all deacons and elders be Calvinists, etc. Numerous reports of this have arisen from especially Southern Baptist congregations that traditionally allowed leaders to be either Calvinist or non-Calvinist.Now I am beginning to hear reports of denominations that have traditionally included both Calvinists and non-Calvinists subtly attempting to impose Calvinism by means of new statements of faith or amendments to old statements of faith. Usually this happens under the guise of attempting to rule out open theism."
Roger Olson warns of the Calvinist takeover of Evangelicalism.
