More has probably been written on the subject of prayer than on any other Christian topic. This encyclopaedia brings together some of the most helpful prayers and teaching of prayer and praise of the past two millennia. It collects the rich and often neglected heritage of the classic Christian past. The focus is on prayers addressed to one of the Trinity. Feature pages and separate sections include Roman Catholic and Orthodox teaching on prayer. Sources range from Abelard, Acarie, Aeldred, Aethelwold, Alcuin, Francis Alexander, Alford, King Alfred and Ambrose, to John Wesley, Westcott, Whittier, Woolman, Xavier and Zwingli.
