Robert McKenna

Robert Fidelis McKenna, O.P. (8 July 1927 – 16 December 2015) was a Dominican bishop. He was known for his traditionalist Catholic positions and is an advocate of sedevacantism. He is also known from the Fox TV-movie The Haunted, which is about the Smurl haunting where McKenna conducted two exorcisms.

He was ordained a Roman Catholic priest for the Dominican Order in 1958 by Cardinal Amleto Giovanni Cicognani. After the Second Vatican Council, while working as a translator and scientific researcher for his religious Order, he became increasingly concerned with the ramifications of the Vatican reforms, and finally removed himself from those in his Order with whom he felt he could no longer associate in good conscience. He continued as a Dominican priest while joining other priests in the Orthodox Roman Catholic Movement (O.R.C.M. or ORCM), a traditionalist Catholic organization founded by Father Francis E. Fenton that represented itself as preserving authentic Roman Catholicism from what its members viewed as radical modernist changes in doctrine and liturgy. The ORCM still exists as a corporation for legal purposes, but has long ceased to be used to represent a religious organization. As early as his October 1985 issue of Catholics Forever, Father McKenna referred to his involvement historically as "in ORCM days".

Fr. McKenna was consecrated a bishop on August 22, 1986 in Raveau, France by Mgr. Michel Guerard des Lauriers, O.P, one of the bishops consecrated by Bishop Ngo Dinh Thuc without papal mandate.
