Did you know that you don’t have to be a Christian to say a prayer talking about ‘crosses’ and ‘churches’? No, neither did I. And did you know that suggesting that Jews might not be comfortable saying such a prayer is being as intolerant as the worst fundamentalist? No, neither did I.
‘Crosses’ and ‘churches’ are Christian symbols – exclusively. They have no place in Jewish religious rituals (I can only speak as Jew in this instance). Many Jews would find mentioning those words in a prayer abhorrent. How could they forget that thousands of other Jews were murdered in the name of the Church, by hordes of devout Christian brandishing crosses? The Christian religion is not universal (it might have wanted to be, once upon a time, but it didn’t manage it, quite). There are prayers that mention god without being so specific; those are fine.
During the war, trying to escape from the Gestapo in la France profonde, my mother was hired as a companion by an old woman, who had portraits of Hitler and Pétain above her bed (could there be a safer place to take refuge in?). Every night, on her knee, the woman prayed God for them. My mother was trying to ‘pass’ as a Christian: she had dyed her hair blonde; she wore a cross and went to church. She was forced to: her life was at stake. She played that difficult role for a few months, until the woman, who was very kind to her and completely unaware of her real identity, gave her away – unwittingly – to a member of the French milice. Luckily, my mother had heard them talking and she left at the earliest opportunity.
I am not a religious Jew, but I would only consider wearing a cross if my life depended on it. As for churches, I like visiting them, for their beauty, their architecture, their art, and I have attended the odd wedding/funeral in them, but I would not worship there.
I don’t care what you believe; just don’t impose your beliefs or your religious symbols on me. And don’t accuse me of intolerance when I object to your trying to do so.
