The legend that St James found his way to the Iberian Peninsula, and had preached there is one of a number of early traditions concerning the missionary activities and final resting places of the apostles of Jesus. Although the 1884 Bull of Pope Leo XIII Omnipotens Deus accepted the authenticity of the relics at Compostela, the Vatican remains uncommitted as to whether the relics are those of Saint James the Greater, while continuing to promote the more general benefits of pilgrimage to the site. Pope Benedict XVI under went a ceremonial pilgrimage to the site on his visit to Spain in 2010.[
