Your Greek Orthodoxy priest seems to ignore all the other passages in the new testament that go to the heart of the matter of earthly wealth. Christ is saying that you cannot have two gods and it is very likely that if you have enormous wealth, you have placed a God before His/Him. He did not say it was impossible, merely improbable. When a rich man asked Him what he should do in order to gain the Kingdom of heaven, he was told to sell all of his posessions and give the money to the poor. I defy you do explain that as a screw up in translation. I have often seen or heard the rich try to alter the meaning of the admonitions in the bible regarding the rich because they want to claim that God blessed them more than He did the poor. Those want the riches of Heaven AND the riches of earth, in many cases because they are greedy. This very fact seems to demonstrate their inherent inability to comprehend God's word. You don't get to have both unless you are very very very careful and being that careful is not in the inherent nature of the wealthy.
Shall we compare the horrors of rapists and murderers when compared to some - I repeat - some, of the wealthiest? Some of the wealthy gain their wealth by trading arms - so they are in a sense, mass murderers. Some gain it by lying on a massive scale, some by vending poisons or spreading poisons upon the ground or into the air or the water. Can you rightly compare one who kills an entire family with one who sickens entire towns? One who rapes a few women with one who rapes the land itself?
But, this pertains only to those who proclaim to be Christian. Those who are not, well, there is still the scientific studies.
