Be convinced of this: your apostolate consists in spreading goodness, light, enthusiasm, generosity, a spirit of sacrifice, constancy in work, deep study, complete self-surrender, being up-to-date, cheerful and complete obedience to the Church, and perfect charity. Nobody can give what he does not have. (Furrow, 927)
Don't let your life be barren. Be useful. Make yourself felt. Shine forth with the torch of your faith and your love. With your apostolic life, wipe out the trail of filth and slime left by the corrupt sowers of hatred. And set aflame all the ways of the earth with the fire of Christ that you bear in your heart. (The Way, 1)
You are to be yeast within the great multitudes that make up humanity remember we are interested in all souls. In this way, with God's grace and your own correspondence to it, you will act as leaven throughout the world, adding quality, flavour and volume to the bread of Christ so that it can nourish the souls of others. (The Forge, 973)
Don't be narrow-minded men or women who are immature, short-sighted and incapable of embracing our supernatural Christian outlook as children of God. God and daring! (Furrow, 96)
The Lord wants a definite apostolate from you, such as catching those one hundred and fifty-three big fish -- not others -- taken on the right-hand side of the boat.
Many years ago now, I saw most clearly a truth which will always be valid: the whole web of society needs to live anew and spread the eternal truths of the Gospel, since it has departed from Christian faith and morals. Children of God at the very heart of that society, of the world, have to let their virtues shine out like lamps in the darkness -- quasi lucernae lucentes in caliginoso loco. (Furrow, 318)
You are salt, apostolic soul. 'Salt is a useful thing', we read in the holy Gospel; but if the salt loses its taste, it is good for nothing, neither for the land nor for the manure heap; it is thrown out as useless. You are salt, apostolic soul. But if you lose your taste... (The Way, 921)
You need interior life and doctrinal formation. Be demanding on yourself! As a Christian man or woman, you have to be the salt of the earth and the light of the world, for you are obliged to give good example with holy shamelessness.
