Criteria for selecting the true church

This is just one of the best quotes I've read in a long, long time; it just slapped me upside the head. I was led here by a very offensuve anti-Mormon propaganda video series that made me look up LDS on my favorite religion website, www.religioustolerance.org, which, as it is often wont to do, led me into a series of random essays about religions.

Criteria for selecting the true church:
"If Christians really could have assessed the will of God [through prayer], the original conflicts between Jewish Christians and Pauline Christians in the first century CE -- and the thousands of conflicts since -- would have been resolved, and there would have been only a single Christian church throughout history."
