I'm engaged on a study programme with the Interfaith Foundation here in the UK, and yesterday I was reading up some summarised information about Judaism. It was a shock to find out that I'm Jewish after all.
Ignoring the racial and cultural (and surgical!) elements, which I'm never going to have as a 'goy,' and simply focusing on the core tenets of belief, I found that I had almost no objections to the basic propositions of Judaic belief. Certainly I had no more objections than I do to the Christian faith I was raised in.
Perhaps this is what St Paul referred to as the circumcision of the heart. No doubt there would be many obstacles in adopting a new faith like Judaism (the non-cardiac circumcision being one of them) so I'm fairly certain I won't be doing that any time soon. But the tantalising possibility is emerging of being not only a Citizen of the World, but perhaps also, in the same way Prince Charles has spoken of, being if not a member, at least a Defender of Faith.
