Where did Mitt get his seed money

Does anyone besides me wonder where Mitt Romney got his seed money to start Bain Capital with such a big bang?  My bet is the church.  It took a large chunk of private capital to start up that company and make that much money in the time he did it.  And he is listed as the sole stockholder. Does that mean that all these people just gave him the money?  Not likely.  And reading about the church's ways of taking care of their own, my guess would be that the church put up the money for a tidy return.  Another thing, why are churches allowed to act like corporations all the while screaming freedom of religion.  Me, I think that all churches should have to keep records and prove that they are not engaging in for profit capitalism and that they are not engaging in politics.  I'm all for freedom of religion.  But I am not for corporations disguising themselves as churches to avoid paying taxes.  Freedom of religion, to me, means being allowed to worship or not wherever and whenever you chose.  It does not mean that a so-called church can acquire obscene wealth just for being a church.  Time to audit and tax.
