"Do you have any idea of how those money changers were worse than today's false preachers?"
No I don't.
I invite you sincerely to educate me.
The "money changers" are targeted as the bad guys by the early Jewish gospel writers, to avoid friction with the Temple. The gospel writers were not as fearless as has been supposed.

Just to get started, the currency of the time was a mix of coinage (no paper) which reflected the multicultural nature of the Roman Empire and included Jewish shekels, Greek drachmas and Roman denarii and various lesser currencies. Exchange rates between them all were well determined before Yeshua.

My study of Jewish culture of the 1st century AD suggests that there money changers in the Temple who exchanged Roman and Greek currency for Jewish currency, which was the only tender the Temple would accept for sacrificial services. The reason was because the Tyrian shekel minted in the city of Tyre was the only coinage of the time that bore no image of a mortal king (refer ten commandments). The sacrifice money was for the Mosaic prescribed preparation and ritualised and prayer ladened despatch of the live animal sacrifices by the priests who were Pharisees and Saducees.

Sacrificial animals, meeting the strict sacrificial requirements of purity and ranging from small birds to large animals, sold in the Temple court yard, could be paid for in any currency. I have not ascertained if the priests were involved in this trade but I feel certain they had to be involved in approving the sacrificial purity and most likely for another fee.
Luke 12:6 mentions what may have been an early "five for the price of four" deal, five sparrows, presumably for sacrifice, not much meat on a sparrow to eat, for a mere two farthings, cheap as chips.

As the Temple in Jerusalem was the only sanctified place where blood sacrifices could be made in all Judea, it was a thriving concern.
For those who had to travel long distances to the Temple and did not bring their own, or for those urban locals who had an "impulse" need, sacrificial animals were available for sale. The Temple would have looked sounded and smelled like a combination livestock sales yard, abattoir, and Ray's Barbecue Shack (without any special sauce). Its no wonder Yeshua got the shits about the ritual shenanigans in the sacred Temple.

Of course the money changers charged a fee for their service but they also had to pay a stall-holder lease to the Temple for their spot in the courtyard. Visitors to the Temple, sacrificing or not, paid a Temple tax of two drachmas or two denarii per head. A single denarii was equivalent to a day's wages for a labourer at the time. so the price of admission was a hefty one.

So your poor worshipper arrives at the Temple with no sacrifice, pays two denarii to the Temple just to enter, can spend up to any amount on a sacrifice to the stall holders, but must pay the money changers a fee for exchanging their drachmas and denarii for shekels to pay the priests to make their sacrifice and all he can do is hope his considerable investment, his sacrifice, his plea to his god is answered.
This was the massive lucrative confidence trick to which folks like Yehsua ben Josef objected to that led to his supposed trashing of the Temple courtyard. Yeshua is quoted as preferring worship to be private, modest and only between the believer and his god, just as he prescribed in the Sermon on the Mount.

The "money changers" were tagged as the "bad guys" by the gospel writers instead of the Temple and its requirement for blood sacrifice and coin in exchange for intercession with "God". They knew the Temple authorities had already commercialised the faith but they deflected the charge because early followers of Yeshua still worshipped in synagogues when as tolerated heretics it would have been most imprudent to offend the Temple.

If you were looking for a comparison for the wealthy megachurches in the world today, its not found in the 'money changers'. but rather in the basic business plan erected over 2,000 years ago by the Temple in Jerusalem, which was only merely an early megachurch that enjoyed a monopoly and charged money at every conceivable point of contact with worshippers and small business operators. And, just by the by, the priests were also allowed to take a free share of the meat from the sacrifices as well for their own consumption.

At worst the money changers were making a profit on currency exchange, not by peddling any 'prosperity gospel'. They weren't preventing the Jews from understanding their traditional relationship with Yahweh, they were facilitating the means of their worship as prescribed by their Torah, the Law and the Temple. You seem to be confusing Christian and Mosaic faiths by demonising the Jewish money lenders as being more evil than modern Christian personality based mega churches.

@FishNChips007: Al, you are woefully ignorant

Oh dear. Did I touch a nerve?

The money changers were conducting a perfectly legal business. People came from all over to the temple and needed local money to buy animals for sacrifice. So the money changers were helping to meet a demand created by your god's strange appetite for burnt flesh. At least they weren't burning people yet.

The Nazis? Of course they had "Gott mitt uns" on their belts. They were doing god's work. Hitler said as much in "Mein Kampf". The Holocaust was part of a long Christian tradition.

BTW, do you know which government was the first to sign a treaty with the Nazis? Look up Reichskonkordat.

Yes I'll judge god and Jesus and all their deluded followers for all the harm they've caused and continue to cause.

FishNChips007 Al, Did you even read what I wrote?

Now that's a fucking irony overload, you never honestly address what people post.

FishNChips007 "Sounds pretty arrogant and self-righteous to me,"

Ahahahahahahahhahha, from the man who believes the entire universe and everything in it was created for one evolved species of ape he happens to belong to.

FishNChips007 "Just because someone claims to be Christian does not mean they are. Someone who follows Christ will not murder, be a war-monger, or rape a child."
"

Bullshit, and again this is a No True Scotsman Fallacy, and a spectacularly stupid one as well, as it is manifestly untrue, try reading the fucking bible ffs, the followers of the deity portrayed in there, and the deity, do nothing but commit murder. As for raping children it is endemic amongst the priesthood of the largest oldest christian church in the world ffs.

@ Hey Fishy!!! RE: "I told you I would be twice dead if I got what I deserved."

FINALLY!! We are all in fucking agreement.

'Your debt has been paid? Ha ha ha ha ha ha ha... you are fucking delusional." There are no get out of jail free cards. There are only assholes who pretend they have "get out of jail free" cards. You are personally responsible for all you do. LEARN TO FUCKING LIVE WITH IT! Your stupid fucking God does not get to forgive you for the asshole things you have done to others. GO FUCK YOURSELF.
