Cardinal Robert Sarah, prefect of the Congregation for Divine Worship and the Sacraments, is pictured at the Vatican in this Oct. 9, 2012, file photo. Cardinal Sarah, the Vatican's liturgy chief, has asked priests to begin celebrating the Eucharist facing east, the same direction the congregation faces. Although not commonplace, the practice is already permitted by church law. Cardinal Sarah made his request during a speech at the Sacra Liturgia conference in London July 5.
