 Cogitosus had written a "Life of Saint Bridget", much in the same style as Muirchú's "Vita" and the hagiographies were used to contest supremacy for their separate churches.According to Muirchú, Patrick founded his main church at Armagh, and stated in his work that Armagh was beloved by Patrick.In the "Vita", Muirchú writes that Patrick intended to die in Armagh, and though an angel convinced him not to specifically go there, the angel stated that Patrick's ‘pre-eminence’ would be at Armagh.
