The decision to raise their children communally with no involvement from the parents is bizarre.
Give the whole story. During these battles with the Church liberals attacking them, many of the members of St. Benedict Center felt drawn to the religious life, indeed, to beginning an Order dedicated to defending the Faith and orthodox doctrines. They knew what was coming to the Church. Many of these people were married. Some had children. As has happened with other religious, including saints, with the agreement of each spouse, they began the MICM. Fr. Leonard Feeney was the Superior, and co-Founder with Sr. Catherine Clarke and Brother Francis Maluf. It was unusual for these modern times, but not in Church history - and the finger of Our Lady was there. The children involved because of the circuмstances, were the happiest on the face of the earth. Naturally, it was important that this particular order would be infiltrated, and stress was placed on "getting to" the children, and breaking them up. Years later, after several attempts, Jєωs were able to further "get to" some who had left and get them to write, or back, disparaging books. Neither are they traditional Catholics. Again, Fr. Feeney was the worst nightmare of the enemies of the Church. A famous, able priest, who was rising in defense of No Salvation, just as they were about to throw the Ecuмenism bomb against the Church. He had to go. And his "group" with him.
Fr. Robinson had Fr. Wathen as priest. For him to enter SSPX and "rise," if such was his interest, (indeed, to perhaps even enter), he would have to put him down - but also, to rise in SSPX it is worth a few points to "make your bones" as an anti-Fr. Feeney mouthpiece. But he more Fr. Robinson does open his mouth on these things, the worse he gets. And because he once knew better, he will have to answer for it. Sometimes, thinking yourself smarter than everybody, because it is what you have heard all your life, turns into you just being the bigger fool on that account.
