What do you think about a church offering an affinity credit card as a fundraising gesture?

People can obtain credit cards with their college, their sports team, their professional organization, et al. Now, I know of a church which wants to offer her own affinity credit card. At the recent embly, I voiced my objection based on fundamental grounds - churches should not be in the business of promoting debt. Yet, many people spoke in favor of the measure. I can see the "good steward" argument in a credit card but given how many people are in debt thanks to credit cards - a church should not place her image on an instrument of debt.
