Protestantism today has an idolatry problem. Not merely in the sense of worshipping false gods—of pleasure, wealth, or politics—but in the sense of worshipping the Triune God of Scripture according to images and ideas of our own devising. Whether it’s a God who suffers and changes alongside his creatures, or a “Trinitarian circle dance” of divine personalities, or a hierarchically-arranged Trinity that serves as a blueprint for gender relations, modern evangelical theology has strayed far from historic Christian orthodoxy.
