The Communion of Saints comprises, and is made fruitful by, three great vital movements. A stream of ardent love flows from the Church Triumphant to the members of Christ on earth, and thence returns in countless rushing brooks to the blessed in heaven. A similar traffic of love takes place between the members of the Church Suffering and the Church Militant. And thirdly that same communion operates between the several members of the Church Militant, producing those fruitful centers of life whereby the earthly fellowship is continually renewed.
