- Catholic Encyclopedia: Jerusalem (A.D. 71-1099): "During the first Christian centuries the church at this place was the centre of Christianity in Jerusalem, "Holy and glorious Sion, mother of all churches" (Intercession in "St. James' Liturgy", ed. Brightman, p. 54). Certainly no spot in Christendom can be more venerable than the place of the Last Supper, which became the first Christian church."
