Of course if don’t believe the New Testament, you can always turn to that great defender of wealth and privilege, the Old Testament:
“Woe to those who make unjust laws, to those who issue oppressive decrees, to deprive the poor of their rights and withhold justice from the oppressed of my people, making widows their prey and robbing the fatherless. What will you do on the day of reckoning, when disaster comes from afar? To whom will you run for help? Where will you leave your riches?”
— Isaiah 10:1-3
"This is what the Lord Almighty said: “Administer true justice; show mercy and compassion to one another. Do not oppress the widow or the fatherless, the foreigner or the poor. Do not plot evil against each other.” — Zechariah 7:8-10
If anyone is poor among your fellow Israelites in any of the towns of the land the Lord your God is giving you, do not be hardhearted or tightfisted toward them. Rather, be openhanded and freely lend them whatever they need.
— Deuteronomy 15:7-8
Whoever oppresses the poor shows contempt for their Maker, but whoever is kind to the needy honors God. — Proverbs 14:31
Do not exploit the poor because they are poor and do not crush the needy in court, for the Lord will take up their case and will exact life for life. — Proverbs 22:22-23
There are, of course, many, many more passages like this. Maybe it’s just me, but it sure looks like God is pretty worked up about helping the poor. Maybe we should be, too.
