Love is more than a feeling. A priest and a rabbi teaching together has been a very rich experience, because Christians get a little lazy when they talk only to themselves.
Interpreters miss nuances and understandings when they try to interpret scripture in a vacuum.
I've learned a great deal from my rabbi friend, and from Jewish participants in this course, about the Jesus that I thought I already knew. One of the most important things I learned was that we have been one-dimensional and unfair to the Sadducees and the Pharisees. Good church-going people who were accustomed to hear the round of gospel readings, we are more or less conditioned to give a hissing response when we hear about the Pharisees. At the hands of the varied perspectives of the gospel writers, the Pharisees are usually the enemies. The Pharisees are said to argue with Jesus, to trap him in his own words, or to expose a flaw in his understanding of the scriptures.
