Most Holy Family Monastery

[2] Initially incorporated in 1993 as the Queen of Angels Corp, the Most Holy Family Monastery is a New York Domestic Not-For-Profit Corporation under the business type "religious organization".

[10] Michael and Peter Dimond condemn natural family planning (a fertility awareness method for married couples to regulate conception, pregnancy, and birth).

"[16] Frederick Dimond (Brother Michael) is the author of UFOs: Demonic Activity & Elaborate Hoaxes Meant to Deceive Mankind, published in 2008 by Most Holy Family Monastery.

They also hold that even the Tridentine Mass as permitted by Benedict XVI in his 2007 Summorum Pontificum, is a compromised form of liturgy, because the 1962 Roman Missal that he approved includes changes made by Pope John XXIII, who they believe to be an antipope.

Previously, attending the Divine Liturgy at a Byzantine rite Catholic Church, in Rochester, New York, was considered appropriate; MHFM now advise their followers to stay home on Sundays and pray the rosary.

"[19] This category is said to "routinely pillory Jews as 'the perpetual enemy of Christ' and worse, reject the ecumenical efforts of the Vatican, and sometimes even assert that recent popes have all been illegitimate.

They are incensed by the liberalizing reforms of the Second Vatican Council, which condemned antisemitism and the accusation that the Jewish people are collectively responsible for deicide in the form of the crucifixion of Christ in the document Nostra aetate.
