A 22-year-old atheist writes:
…here’s my proposal. Everytime I come home, I pass this old Irish church. I promise to go into that church every day– for a certain number of days– for at least an hour each visit. For every $10 you bid, I will go to the Church for 1 day. For $50, you would have me going to mass every day for a week.
My promise: I will go willingly and with an open mind. I will not say/do anything inappropriate. I will respectfully participate in service, speak to priests, volunteer with the church if possible, do my best to learn about the religious beliefs of the church-goers, and make conversation with anyone who is willing to talk. (Though I do reserve the rights to ask the person questions about the faith.)
Here is the ebay link, there has been plenty of bidding, and thanks to Josh Glassman for the pointer.
