“Charity is the salt of the apostolate”
Love and practice charity without setting any limits or discriminating between people, for it is the virtue which marks us out as disciples of the Master. Nevertheless, this charity cannot lead you to dampen your faith - for it would then cease to be a virtue. Nor should it blur the clear outlines that define the faith, nor soften it to the point of changing it, as some people try to do, into something amorphous and lacking the strength and power of God. (The Forge, 456)
It would be naive to think that the demands of Christian charity are easy to fulfill. Our day to day experience of the affairs of men, even unfortunately within the Church itself, tells us a very different story. If love did not bid us keep silence, each could tell a lengthy tale of disunity, personal attacks, injustice, slander and intrigue. Let us admit it openly, and try for our part to apply the right solution to the problem, which should consist in our personal efforts not to wound or ill‑treat anyone, and not to humiliate others when we have to correct them...
I feel moved right now to ask Our Lord (and if you wish you can join in my prayer) not to permit uncharitableness to sow its cockle in the Church. Charity is the salt of the Christian apostolate. If it should lose its taste, how can we come to the world and proclaim: ‘Here is Christ?’ (Friends of God, 234)
