‘And he instructed them to take nothing for the journey except a staff − no bread, no haversack, no coppers for their purses. They were to wear sandals but, he added, “Don not take a spare tunic”.’ (Mk 6:7) The point is not what they don’t take with them, but what they do. We can imagine, how they will feel this special ‘something’ when they feel a bit chilly, and would instinctively put on their back their spared tunic. Or, when their sandals got out of shape, and they put on the spare one. But no. This sensation soon gives place to a special peace and warmth in their hearts. They just feel the gentle weight of their friendship with their Master. Through this being stripped of their concerns (their engineering their future, and being in control), they can just focus on their new inner force. Literally, they walk in the Spirit. Defenceless, but fully protected.
From that special first walk, from the mixture of dust and their footsteps, emerges all theology and Christian wisdom. ‘There is an unparalleled likeness, there is an unparalleled correspondence between God and man because of their reciprocal perfection. This does not mean that God can receive any perfection from man. But just as man cannot be perfected except by the divine goodness, so also divine goodness can rightly exercise its perfection outside itself nowhere so well as upon our humanity. The one ahs great need and great capacity to receive good; the other has great abundance and great inclination to bestow it…The more of affluence the good possesses, the stronger is its inclination to diffuse and communicate itself.’ (Saint Francis de Sales, Treatise on The Love of God, chapter 15.)
