Opus Dei, the most mysterious and controversed institution of the Catholic Church.
Bishop Javier Echevarria, head Prelate of Opus Dei, at the Opus Dei international headquarters, villa Tevere, Rome, an architectural grouping designed by Opus Dei founder Josemaria Escriva de Balaguer, where the Prelate's councellors reside and where Echevarria's two predecessors are buried, Escriva de Balaguer and Alvaro del Portillo. Although composed of 98% laity, Opus Dei is a universal diocese and can only be governed by a bishop. Bishop Echevarria, elected Prelate for life, then confirmed by the Pope, is the third Opus leader after its founder Josemaria Escriva de Balguer deceased in 1975 and his successor Alvaro del Portillo deceased in 1994.
