I can't begin to tell you how THRILLED I was to find you actually agreed with me about something - or maybe not "agreed" put "don't exactly disagree"! It's almost like Christmas morning accessing my pings and seeing this!
The part of your comments that I exactly DO disagree with is your contention that, "Obviously, if someone makes money and then donates all of it, then he is fine per the Gospel". This sounds suspiciously like buying ones way into heaven. Is this what you are saying? I'd point you to that great wedding chapter of I Corinthians 13, where Paul states, "If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing." (I Cor. 13:3) So, sorry, even IF one gave everything they owned to the "poor", it would NOT be fine per the Gospel. Receiving the gift of everlasting life by the grace of God through faith is what saves and is perfectly fine per the TRUE gospel.
Well, no, obviously, the donation must be in love, just like St. Paul says. But it must be made, -- in love -- or else the wealth has gotten hold of the rich man's soul. It is very, very hard to be rich and gain salvation; the idea that economic life can be separated from life of piety and humility is one of the greatest damages Luther did to mankind.
