Not by the wildest of longshots. Hardly a jovial chap (Matthew 10:34, Luke 19:27 and 22:36, Mark 3:5, John 2:15); not a big proponent of plants (Matthew 21:18-19) or animals (Matthew 8:32); held questionable family values (Luke 14:26, Matthew 8:22 and 10:35-36, John 2:4); didn't mind slavery (Luke 12:47); propagated poverty (Mark 14:3-7); had no sense of time (Matthew 16:28, Revelation 3:11); was far from humble (Matthew 12:6, 12:41, and 12:42); and occasionally ignored his own advice (Mark 2:23, Matthew 21). Most of his parabolic examples are shrouded in a fog that can range from intentionally mysterious to dangerous, and his more-lucid instructions (Matthew 5:13-16, 5:29-30, 5:32, 5:39, 5:41-42, 6:19-20, 6:34, and 19:12, Luke 6:30, 12:33, and 19:23-26, John 6:27) are routinely ignored by the overwhelming majority of his followers. His only ethical contribution was the concept of infinite punishment for finite crimes. He could have imparted some wisdom concerning science or medicine (being omnipotent and all), but seemed oblivious to it all. The Golden Rule was cute, but Confucius had already done it 600 years earlier. No, the inquiring mind has always been and will always be the greatest teacher known to human beings.
