The Gospel is from St. Luke, 10:38-42 and recounts the familiar story of Martha and Mary. St Augustine comments on this scene as follows: "Martha, who was arranging and preparing the Lord's meal, was busy doing many things, whereas Mary preferred to find her meal in what the Lord was saying. In a way she deserted her sister, who was very busy, and sat herself down at Jesus' feet and just listened to his words. She was faithfully obeying what the Psalm said: 'Be still, and know that I am God' (Ps 46:10). Martha was getting annoyed, Mary was feasting; the former coping with many things, the latter concentrating on one. Both occupations were good" (Sermon 103).

Martha has come to be, as it were, the symbol of the active life, and Mary that of the contemplative life. However, for most Christians, called as they are to sanctify themselves in the middle of the world, action and contemplation cannot be regarded as two opposite ways of practicing the Christian faith: an active life forgetful of union with God is useless and barren; but an apparent life of prayer which shows no concern for apostolate and the sanctification of ordinary things also fails to please God. The key lies in being able to combine these two lives, without either harming the other. Close union between action and contemplation can be achieved in very different ways, depending on the specific vocation each person is given by God.
