This is a full length portrait of one who was a most interesting and controversial figure in American church life during the fore part of this century. Born into the Episcopal Church, Lewis Wattson became one of the outstanding leaders in the ""high church"" or Anglican wing of that body. His agitation for reunion with Rome created a great disturbance and no doubt many of his fellow churchmen were relieved when he finally went over to Rome. Since that step he has been widely known and greatly beloved as ""Father Paul"". But large as his theological battles loomed in his life, when he died in 1940 he was mourned principally because of his efforts in the field of Catholic social welfare. Even as an Anglican he made of Graymoor not only a monastery for the Society of the Atonement, but a centre of welfare and educational work. He was the originator of the Church Unity Octave which, today, as a movement for concentrated prayer for the reunion of Christendom, is one of the most powerful instruments used by the Catholic Church for the conversion of non-Catholics. He also founded the Catholic Near East Welfare Association and was a great champion of the cause of foreign missions. He was greatly interested in the poor and homeless and made of Graymoor a haven for the destitute and the friendless. It is a vivid story of a vivid personality. Both Catholics and Anglicans will find it absorbing.
