Tocqueville wrote (p. 297 of the Lawrence-Mayer ed.):
As long as religion relies only upon the sentiments which are the consolation of every affliction, it can draw the heart of mankind to itself. When it is mingled with the bitter passions of this world, it is sometimes constrained to defend allies who are such from interest rather than from love; and it has to repulse as adversaries men who still love religion, although they are fighting against religion's allies. Hence religion cannot share the material strength of the rulers without being burdened with some of the animosity roused against them.

Just the other day I received a note from a friend of mine, a pastor, who told me he no longer uses the label “evangelical” to describe himself, even though he meets every element of its historical definition, “because the term is now so stained as to ruin my ability to be what evangelicalism was supposed to be.”
Another pastor who is a lifelong friend told me, “Evangelical is no longer a word we can use.” The reason, he explained, is that it’s become not a religious identification so much as a political one. A third person, who heads a Christian organization, told me the term evangelical “is now a tribal rather than a creedal description.” In October, the Princeton Evangelical Fellowship, a campus ministry for more than 80 years, changed its name to the Princeton Christian Fellowship. “We’re interested in being people who are defined by our faith and by our faith commitments and not by any sort of political agenda,” according to Bill Boyce, who has led the campus group for decades.
