Take Protestantism, drop it in the American context, and what do you get? A proliferation of schisms and denominations.
Protestantism broke off of the Roman Catholic Church in the sixteenth century and quickly formed different streams of Protestants after Martin Luther and Huldrych Zwingli failed to find agreement over the meaning of the Lord’s Supper. Fast forward to the early years of the United States when the young republic disestablished religion, and there you find Christian sects—and some not so Christian—forming even more rapidly.
Now in the twenty-first century, with the vast diversity of Protestant denominations, one wonders what unifies this colorful array of Christians? Anthony Chute, Christopher Morgan, and Robert Peterson suggest that denominationalism is not essentially at odds with evangelical unity, and in their book, Why We Belong: Evangelical Unity and Denominational Diversity (Crossway, 2013), they probe this question from several angles, pooling the insight of evangelicals in several denominations to offer a helpful foray into the tension of unity and diversity in the church today.
