It is wrong, and a jewish banking scheme, to charge interest to a Catholic church or chapel. In fact, the entire jewish banking scheme is immoral-- and interest should never be charged. Maybe SSPX priests should read some of the seventh and eigth grade readers that its students (should be ) read (ing).
The Hebrew word for interest is neshekh, which means, closely, "a bite", as , "to loan money to the goy and take a bite out of him." Read Father Charles E. Coughlin's excellent book "Money, Questions and Answers" or his
"Suicide of Capitalism."
Christ's parable was NOT to instruct Christians to loan money to each other, and thereby derive an income from the money; it was to invest the money in capital, which improved commerce or business, and thereby returned a value for the investor.
This money-loaning scheme, which the SSPX uses all over, is part and parcel of the SSPX' drive for more and more money at any cost-- build up the buildings, water down the faith so anybody will enter, then exact the principal with interest from the faithful. ( Contrast this with the old SSPX which advised against going into debt!). This reported scheme is likely the arrangement which Krah and the jewish Rothschild group made with Fellay and Co. to build the new taj mahal seminary-- now they need to accept Vatican II and all its errors; so as to get the seminary rooms full of novus ordo boys--with their parents and/ or the novus ordo bishops paying the bills.
