The Yangtze River's waves drive forward, the preceding wave dies on the sand.
Catholicism initially promoted 'justification by works,' where 'works' represent the righteous people in the Bible, the cherished of God, those close to the deity.
But this 'works' is not about actions, it doesn't mean doing good deeds makes you righteous, rather it's about spending money to buy indulgences from the Holy See; the more you buy, the closer you are to God.
So everyone saw this and thought you are treating people like fools, thus Martin Luther came up with 'justification by faith,' which developed into the Lutheran Church.
As long as you believe in God, you're righteous, no need to go to the Holy See to buy indulgences.
This concept was indeed advanced at the time, but everyone wanted to seize the right to interpret the Bible for personal gain, using religion to ease their moral guilt from wrongdoing.
