"And if you believe strongly in all this, wouldnt the stock market be the house of sin?"
Oh, but it is a house of sin, that many of us all gamble in. Here's what Jesus thought of money grubbers like many of us are; "Jesus calls money “unrighteous” because when we live for it, it makes us evil."
"If wealth is wrong then why is the Catholic church one of the worlds wealthiest entities?"
Good point, but some may even say its hypocrisy, also.
"And I believe that many people can love God and still be wealthy."
Ahh, but some may not believe and still become wealthy, too, a little dilemma going on here.
