The new Virginia seminary is said to cost $64 million. While the property was donated to the SSPX, this is still a hefty sum.
Don't know of any other projects like it.
The seminary will cost $100+ when completed. ALL the properties of the SSPX were paid for by donations, so that is irrelevant, the question is how are the donations used. The seminary is an ostentatious expense and totally unnecessary. It is like a person winning the lottery and going nuts and spending all
the money on building a castle for himself. The SSPX could have done additions to Winona for $5 million. Even that expense is something to seriously think over, when you consider that they "graduate" 8 seminarians a year.
Religion is a very profitable business, unique to itself and unlike any business. From a businessman's perspective the angle of the SSPX is:
A group of trads build a chapel and over time fill it with other Catholics, then they call the SSPX to take the place of their independent priest who left or died or was a nut, and the SSPX trades their priest for all the property. They have a seminary that was bought with donations or given to them, and the seminary expenses are all paid by donations, zero expense, and the seminary puts out priests that bring in properties and money. Trade a priest for property and income from donations.
