Well, just my personal opinion, but I would say that debt honestly taken on with the intention and ability to repay is not sinful. I don’t think things changing making one unable to pay the debt makes it sinful either.
However, I would say that deliberately taking on debt with the full knowledge that one doesn’t have the ability to repay it, or with the deliberate intention to not repay it would be sinful as it would be theft.
Taking on huge credit card debt with the intention of declaring bankrupt to avoid repaying it is far different than taking on credit card debt and than having life circumstances change (loss of job/serious illness etc.) affecting your ability to repay it.
In general I would agree with you. But I would add a of very strong caveat. Bear with me, it will take a while to explain.
There is still such as thing as a sin of usury. Now, many people thing of usury as simply charging too high of an interest rate, but that is too simplistic. Usury occurs when one charges an interest rate that will, in and of itself, make repayment of the interest loan a great burden on the borrower. (It is a more complicated than that, but that suffices for my current argument).
There is no doubt in my mind that almost all credit card companies today engage in usurous practices. They are vultures, often accepting credit from the people not able to pay, and then charge high rates; which provide great burden on people. If one looks closely at the business model of credit card companies, they depend on their profit margins from all types of borrowers: those who use CC as transaction tools only (ie paying them off every month) and those who they charge high rates to. If you miss don’t abide by their rules, they impose very high penalties.
So I believe that using CCs today amounts to either *implicit formal cooperation *with evil:
Implicit formal cooperation occurs when the organization denies intending the wrongdoing of the principal agent, but participates in the action directly and in such a way that it could not be done without this participation.
OR at the very least
Immediate material cooperation:
Immediate material cooperation - Doing something that is necessary for the actual performance of the evil act, directly involved.
So I think using a CC is sinful (note, there may be CC companies that do not practise in these ways, but I don’t know who they are). Now, this is VERY subjective on my part, I admit. Many people would say either CC do not practise usury (they would be simply ignorant, I had to clean up my mentally ill brother’s financial mess a few years ago, and you would be shocked) OR that using a CC in a responsible way is at worse *remote mediate cooperation *with evil (which is not sinful).
But me, I think credit card companies, check cashing companies, pay-day loan companies, pawn shops all practise usury and are great evils in our society. So we should not use them.
One of the failures of the Church leadership in this day and age is not doing a better job explaining what usury is in our modern economy and what usury is not. And not speaking out against the widespread practice, which targets and takes advantage of some of the least fortunate of those around us.
