"Purification and fruit belong together; only by undergoing God's purifications can we bear the fruit that flows into the Eucharistic mystery and so leads to the marriage feast that is the goal toward which God directs history. Fruit and love belong together: The true fruit is the love that has passed through the Cross, through God's purifications. 'Remaining' is an essential part of all this. In verses 1-10 the word remain (in Greek menein) occurs ten times. What the Church Fathers call perseverantia--patient steadfastness in communion with the Lord amid all the vicissitudes of life--is placed center stage here. Initial enthusiasm is easy. Afterward, though, it is time to stand firm, even along the monotonous desert paths that we are called upon to traverse in this life--with the patience it takes to tread evenly, a patience in which the romanticism of the initial awakening subsides, so that only the deep, pure Yes of faith remains. This is the way to produce good wine."
--Benedict XVI, Jesus of Nazareth: Part One: From the Baptism in the Jordan to the Transfiguration (New York: Doubleday, 2007), p. 262
