Answer:
The answer is: the Catholic Church
Explanation:
The Catholic Church is not the only religion that opposes loaning money at interest: Muslims, Jews and other Christians also oppose it. It is considered a sin by many, the term they use is usury.
Probably if you think about it in a religious way, you might believe that interest is bad. I agree that businesses that charge higher interest rates than usual to certain groups of people are doing wrong (e.g. payday loans), but what banks do is not.
It is also a matter of personal belief, because it's easier to criticize someone else, but banks sometimes do good things. They help people buy their houses or pay for expensive medical care.
The world has changed, and will keep changing. Many things that we consider normal now will probably be considered outrageous in 50 or 100 years.
