Michael Dimond

Michael Dimond, born Frederick Dimond and known as "Brother Michael", heads Most Holy Family Monastery (MHFM), a sedevacantist organisation in Fillmore, New York, which he leads together with his brother Peter Dimond (Wikipedia). According to Wikipedia, the community was founded in 1967 by Joseph Natale, and Michael Dimond became its head after Natale's death in 1995; the community is not approved by the Roman Catholic Diocese of Buffalo, whose spokesperson has said it has no affiliation with the Catholic Church (Wikipedia).

Under the brothers' leadership MHFM became known chiefly through its website and videos at vaticancatholic.com, which argue that the post–Vatican II popes are not true popes — the site refers, for example, to "Antipope Francis" — and publish material such as "The Antichrist Identified!" (vaticancatholic.com; vaticancatholic.com). See Sedevacantism.

The Southern Poverty Law Center lists MHFM among "radical traditional Catholic" hate groups in New York (SPLC), a designation Wikipedia dates to February 2017 (Wikipedia); the SPLC has characterised that wider category as an antisemitic movement (SPLC). See Judaism and antisemitism.

In 2010 The Buffalo News reported on a lawsuit by a man who had left the community and accused the monastery of taking $1.6 million from him; Frederick and Robert Dimond declined to be interviewed for the story (The Buffalo News via BishopAccountability). In June 2012 a federal district court in New York dismissed the suit's fraud, misrepresentation, racketeering (RICO), deceptive-practices, false-advertising and equitable claims (Religion Clause via ICLRS).
