A brief summary of the Church’s mission:
386. The proper and specific mission of the Church is to communicate the life of Jesus Christ to all persons, proclaiming the Word, administering the sacraments, and practicing charity. It is welcomed to be reminded that love is shown more in works than in words; that is true for our words in this Fifth Conference as well. Not everyone who says Lord, Lord …. (cf. Mt 7:21). It is our supreme task as missionary disciples of Jesus Christ to witness love for God and for neighbor with concrete works. Alberto Hurtado used to say, “In our works, our people know that we understand their suffering.”
If they think we understand they are more likely to speak with us.
