So I finally got a reply from my MP - I'd actually given up hope. He's Conservative, very right wing, and I disagree with a lot of his voting record. However, I wrote in the vain hope that he would actually get it. He's not on twitter and replies with actual letters so takes a while to get hold of.
I never expected him to quote the Pope in his reply (he's C of E). I haven't been able to post that part as he uses my name close by, but it made me smile.
This all makes for strange bedfellows.
