76 In this way the priest, with grace and peace in his heart, will face with generosity the manifold tasks of his life and ministry. If he performs these with faith and zeal he will find in them new occasions to show that he belongs entirely to Christ and His Mystical Body, for his own sanctification and the sanctification of others. The charity of Christ which urges him on, (123) will help him not to renounce his higher feelings but to elevate and deepen them in a spirit of consecration in imitation of Christ the High Priest, who shared intimately in the life of men, loved and suffered for them, (l24) and of Paul the Apostle who shared in the cares of all (125) in order to bring the light and power of the Gospel of God's grace to shine in the world. (126)
