It is the seat of the Eparchy of Our Lady of Lebanon of Los Angeles along with St. Raymond Cathedral in St. Louis, Missouri.

Monsignor Joseph Daher organized Maronite Catholics into a parish in 1923 named Our Lady of Mt.

Father Paul Meouchi became pastor in 1926 and had a church, hall and rectory built on the property.

On August 2, 1966, the parish decided to accept the offer of St. Peters Roman Catholic Church, on the border with Beverly Hills and Hollywood, which had been made by Cardinal James Francis McIntyre of the Archdiocese of Los Angeles.

Father Chedid was named a Chaplain of His Holiness, with the title Monsignor, in 1969, a Maronite Chorbishop in 1978 and the Auxiliary Bishop of the Eparchy of St. Maron of Brooklyn in 1980.
