It’s not complicated. Jesus said “Those who accept my commandments and obey them are the ones who love me.”
And what are His commandments?
“‘You must love the Lord your God with all your heart, all your soul, and all your mind.’ This is the first and greatest commandment. A second is equally important: ‘Love your neighbor as yourself.’ The entire law and all the demands of the prophets are based on these two commandments.”
and here are some more details:
“If you lend only to those who can repay you, why should you get credit? … Lend to them without expecting to be repaid”
“Give to those who ask, and don’t turn away from those who want to borrow”
How does this square with austerity measures imposed by the wealthy on the poor?
