If you’re in the UK*, please consider adding your name to this petition that supports Pope Benedict’s visit to the UK. At the time of writing there are 759 signatures. The National Secular Society has already collected more than 15,000 signatures in their poll that protests the state paying part of the costs of the papal visit (although that is normal for any state visit: the inviting party, in this case the British government, supplies part of the funds).
The Catholic Church having to pay the full cost of the visit would be like you or I being invited to a party and having to pay for the decorations, the band and the food ourselves.
Credit to Fr. John Boyle for writing about this in his blog.
*Or not. The petition doesn’t seem too bothered by the nationalities of the people who sign.
