The letter was signed by a Mr. Christopher Shannon, dated from 1997. Perhaps if he is still living, some one can locate him and ask about his opinions from his experience at Econe, and why it seems there has not been any similar accusations against Msgr Lefebvre..
This begs the question of whether or not such a letter or such a person actually exist outside of the imagination of Atila, who has an ugly history of using unnamed "sources" and innuendo in order to attack Catholic priests, Catholic bishops and one Catholic Cardinal.
