The article doesn't claim that so it seems your Christian sensitivities have skewed your reading comprehension.
It's referencing a Forbes article using the term to distinguish between thoughtless arbitrary giving vs. giving with purpose:
"Even the most generous Christian philanthropists often don't see the purpose of their giving," says Dr. Mark Rutland, the new ORU president and founder of the Global Servants evangelical ministry. "There are impulse givers, people who give to their alma mater or their church or some particular ministry with which they become familiar—but the Greens are Kingdom givers. ... They consider it an honor; they consider it a mission."
