Prayer serves as the central aspect of the Christian life, by which our faith is formed and by which we offer thanksgiving and praise. The act of prayer was central to the early Irish monastics, serving as a vital aspect of their spirituality and religious practice. The Portus na hEireann, or ""Irish Breviary,"" is a Divine Office text based on the prayers and practices used within the Columbanian tradition. It consists of a series of prayers to be used by individuals, groups, or families to be prayed during a set time. This book includes all canonical hours' prayers as established within the early Irish church with every psalm according to the Douay-Rheims Bible.
