Rob, we obviously define "certain" quite differently. You must mean exhaustive knowledge when you say "certainty", or what else could explain your claimed uncertainty about everything except uncertainty ... and even I, considering your philosophy, don't know why that should be exempt. Can I ask you how you can be certain of this one thing?
I'm not sure what you're trying to do with the rest of your post. You seem to be saying that christians are certain but not certain. This seems like semantics on route to avoidance to me.
That's exactly what I'm saying ... though not exactly. Certain about some things, uncertain about others, not having exhaustive knowledge about all questions of "how" and "why", though having enough to not doubt the thing in consideration. And though the subject matter may be different than, let's say, astrology or a committed relationship, the principles are very similar.
Christians, like most people who are not Christians, believe things certainly while possessing only partial knowledge of them ... on authority, on trust, on experience. If God communicates at all, it wouldn't be unreasonable to expect some degree of trust and authority would properly come into play. The interesting thing is, is that you can't escape this principle, whatever you believe. There is mystery about everything. I've never heard a scientist describe the question "how" comprehensively, much less the question "why". And yet I've never known a scientist who doubted that gravity is a reality, though perhaps he doubted the sufficiency of models and descriptions. But Gravity transcends Newton, Einstein, and Heisenberg.
