There is plenty of Christianity that is philosophical. This is why RC priests usually have a philosophy degree prior to studying theology. The same thought processes apply.
Now I would go as far as say there is nothing in common between Modern or Contemporary philosophy and Christianity...
The problem is that spiritual truths are spiritually discerned, and man, by his own wisdom, cannot come into spiritual truth through human reasoning and thinking (philosophy as it were).
Men MUST be enlightened by the Holy Spirit to understand the things of God.
Which is likely why we will never come up with an adequate explanation of why evil exists and why God appears to be doing nothing to stop it.
But for the purpose of this topic is seems that is all philosophical. At least Arminians try to ground their arguments in Scripture.
And BTW, what is the true benefit of earning a philosophy degree and then seminary? Granted we have folks whondo that, but it is not the norm. Seems kind of backwards to me. Just my 0.02 cents
