The most evident distinction between Franklin Graham and his illustrious father, is Frank's willingness to ruffle feathers.
At the risk of calling Franklin's allegedly hell-raising past a "good thing", I will simply observe that his illustrious father has not been willing to "ruffle feathers" for nigh on 35 years.
Given the influence of Bad Theology and (unavoidable) comparisons to his father, I admit the fear that Franklin's "apple" will not fall far from the "tree". Certainly the "moderate evangelicals" hope that this will be the case -- that Franklin will take up his father's "mantle", and continue Billy's ecumenical habit of turning American Baptistry into the ECT "Roman Baptist Auxiliary" of the Roman Catholic Church.
But, in view of recent events, I have some hope the Franklin's teen-age Rebellious streak will manifest itself in productive ways. The Pope kissed the Koran; and Billy has endorsed the Pope in practically every way short of genuflecting and kissing the Papal Ring. But Franky still calls Islam an "evil religion" (which, of course, it is).
Keep it up, Franky. You need not fill your Father's shoes.... big shoes they are indeed -- but a little fashion-conflicted in Baptist terms, if you get my drift.
You've got the all-important "Big Name"; and, in terms of "Compassionate Conservatism", no-one can doubt the Compassion of your Samaritan's Purse organization. So you've definitely got the "political capital" to strike a blow for theological Christian Conservatism, if you care to.
Keep ruffling those feathers, Franky.
