Fr. Cooper, pray for us!
Requiscant in pace.
A very nice commentary about Bp. Williamson by Fr. Cooper. I don't know much about Fr. Cooper, but I have to assume that he was still associated with the SSPX when he died.
Regarding the naysayers on this thread who have complained about describing Fr. Cooper as a saint, well, those who believe that we, as Catholics, aren't allowed to think that a deceased Catholic is a saint have not really paid attention to the history of the Church. Padre Pio was thought a saint by the laity before he was ever canonized, as was St. Bernadette, and many others.
In the early Church, there were saints who were never formally canonized, but they are still considered saints. Fr. Cooper may indeed be a saint, though he is relatively unknown and obscure.
There are some on this forum who believe that anyone associated with the SSPX cannot possibly be in Heaven, which is unfortunate. It isn't a Protestant notion to believe that a soul may indeed be in Heaven, and therefore a saint. Protestants don't usually believe in saints, in the sense that the Church teaches about saints. Protestants generally don't have a clue at all regarding saints.
