I have no doubt that some who signed the statement simply wanted to affirm the important truth that evangelical Christianity is defined by the lordship of Christ and not by political partisanship. Issuing what is inevitably perceived as a politically partisan manifesto is an ill-chosen means for achieving that purpose. Only the naive or disingenuous among the signers will express surprise that the media depicted the manifesto as an election-year effort to drive a wedge between conservatives and what is portrayed as a more authentic evangelicalism. Whatever the good intentions of some signers, the reporters got the story right.
The fact that Jim Wallis is among the signatories is a dead giveaway.
Update: Stanley Carlson-Thies reminds us that there are some distinctive elements of the evangelical witness that shouldn’t be let behind, so to speak.
