Yes and no. It was a false premise that was used as an excuse. Catholic teachings consider ALL non Catholic religions as false. In other words, only one "true" religion, that being the Catholic church. What did Christ say about church and debt? Mathew 18:20-27
20For where two or three gather together in My name, there am I with them.”
21Then Peter came to Jesus and asked, “Lord, how many times shall I forgive my brother who sins against me? Up to seven times?”
22Jesus answered, “I tell you, not just seven times, but seventy-seven times!e
23Because of this, the kingdom of heaven is like a king who wanted to settle accounts with his servants. 24As he began the settlements, a debtor was brought to him owing ten thousand talents.f 25Since the man was unable to pay, the master ordered that he be sold to pay his debt, along with his wife and children and everything he owned.
26Then the servant fell on his knees before him. ‘Have patience with me,’ he begged, ‘and I will pay back everything.’
27His master had compassion on him, forgave his debt, and released him.
