I have often said that I can go much farther down the road together with a serious, biblically oriented, articulate, firmly-believing Arminian than with a jesting, systems-oriented, unclear, wish-washy, Reformed philosopher. 

G. K. Chesterton helps explain why.

It’s not merely true that a creed unites men. Nay a difference of creed unites men—so long as it is a clear difference . . . So a Tory can walk up to the very edge of Socialism if he knows what Socialism is. But if he is told that Socialism is a spirit, a sublime atmosphere, a noble indefinable tendency, why then he keeps out of its way; and quite right too. One can meet an assertion with an argument; but a healthy bigotry is the only way in which one can meet a tendency. (What’s Wrong with the World 22-23)
