Yes similarly, I was a relatively convinced and practicising Christian for approaching twenty years but the Christian claim that the Rabbis do not correctly recognise the messiah because they are "stiff-necked", "hypocrites" and "blind guides" never really sat comfortably with me.
It doesn't make sense when you think about it. Why would G-d choose the Jews to be His Chosen People if they were unable to recognise His most important message and needed to be educated in this by the rest of us?
The problem, I quickly realised once I started looking into it, was that i was looking at the problem the wrong way round. It is like looking the wrong way down a periscope. If you look at Judaism through the lens of Christianity all you can see is a restrictive dark container. Once you look the right way through the periscope, you can see the light.
