Mitt Romney's commencement address at Liberty University offers a smorgasboard of shout-outs to Christians from every branch of the faith: Martin Luther King, Jr., C.S. Lewis, Billy Graham, William Wilberforce, Rick Santorum. It also, very gingerly, touches on Romney's Mormonism without mentioning it by name.

People of different faiths, like yours and mine, sometimes wonder where we can meet in common purpose, when there are so many differences in creed and theology. Surely the answer is that we can meet in service, in shared moral convictions about our nation stemming from a common worldview. The best case for this is always the example of Christian men and women working and witnessing to carry God’s love into every life – people like the late Chuck Colson.
