 The Ephesine origin of the Gallican Rite rested first upon a statement of Colmán of Lindisfarne in 664 at the Synod of Whitby respecting the origin of Easter and second upon an 8th-century Irish writer who derived the divine office from Alexandria.Archbishop Nuttall also asserted the Eastern origin of the Irish rite.The "Catholic Encyclopedia" disagreed, asserting "(see also Ambrosian Rite)" that the Sarum Rite is "merely a local variety of the Roman, and that the influence of the Gallican Rite upon it is no greater than upon any other Roman variety".
