Bishop Williamson then told me that he never saw any evidence of Urrutigoity's homosexuality while Urrutigoity was a seminarian, priest, or professor at Winona. Bishop Williamson said that Fr. Urrutigoity was eventually expelled from the seminary in Winona not for homosexuality, but for subversive activities, namely, the secret planning of the Society of St. John in concert with others ... Bishop Williamson also told me that he had accompanied this young seminarian when he gave testimony against Fr. Urrutigoity at a Diocese of Scranton inquiry in July 1999. The inquiry was held at the request of Bishop James Timlin of Scranton who sent his auxiliary bishop, John Dougherty, along with another diocesan priest and an attorney, to hear this young seminarian's testimony. Bishop Bernard Fellay of the SSPX had set this whole process in motion when he formally accused Fr. Urrutigoity in a letter to Bishop Timlin dated February 11, 1999. (Jeffrey Bond, Letter)
Whatever the post scandal spin is, Bishop Fellay has been proven correct. The group was homosexual as he stated with predictable results. My understanding is that he himself sent a letter to the bishop which was disregarded.
These are points that should be considered in making a prudential decision. But ultimately when all is said and done, the SSPX did the right thing and the diocese of Scranton did the wrong thing, whatever their reasons were.
