For the most part, Independent Catholic communities possess a sacramental and eucharistic spirituality, often mirroring the sacramental life and theology of the Roman Catholic Church. Most possess a mediatory priesthood and an historic episcopate, which are often the only constants amid diversity that ranges from extreme traditionalism to radical experimentation. Julie Byrne comments: "Independents vary widely, ranging from right to left in the political spectrum. On the right traditionalist churches practice versions of Catholicism more conservative than Rome. These include the Society of St. Pius X, founded by Marcel Lefebvre, as well as the Mount St. Michael's community in Spokane, Washington, and actor Mel Gibson's church in Malibu, California, which made headlines when he directed the movie, "The Passion of the Christ" in 2004. On the left stand groups such as the Church of Antioch, the Ecumenical Catholic Communion, and the White-Robed Monks of St. Benedict."
