From my morning reading, Hughson's With Christ in God:
Whether in the Church Militant, in the Church Expectant, or in the Church Triumphant, we all partake of the life of the divine Head, and we all share it with one another. Each soul participates in the life of every other soul in the Body of Christ, and whatever gifts, graces, or glory one receive, all receive, each in his appointed measure. "If one member be honoured, all the members rejoice with it," because the gifts of life and love, of grace and glory, made to one, flood every soul who abides in the same Mystical Body. Every increment of glory in which the saints in heaven rejoice is the increase of the God-life to every soul in Christ. On earth, every prayer and aspiration addressed to God, every good Communion made, every holy action performed, releases the further power and love of God for the benefit of all. A little child half-way round the world offers a simple act of praise or prayer and each of us, even the saints in heaven, has an integral part in that act, and is stronger in the Lord, and in the power of His might, because of it. Far away some soul, beset by temptation, tottering on the brink of the abyss of sin, is, by every exercise of the divine life in the humblest member of Christ, strengthened to stand the more stiffly against the assaults of the adversary, and to win a victory for the honour of God and the kingdom (378).
