Silence and contemplation have a purpose: they serve, in the distractions of daily life, to preserve permanent union with God. This is their purpose: that union with God may always be present in our souls and may transform our entire being. 

Silence and contemplation, characteristic of St Bruno, help us find this profound, continuous union with God in the distractions of every day. Silence and contemplation: speaking is the beautiful vocation of the theologian. This is his mission: in the loquacity of our day and of other times, in the plethora of words, to make the essential words heard. Through words, it means making present the Word, the Word who comes from God, the Word who is God. 

Yet, since we are part of this world with all its words, how can we make the Word present in words other than through a process of purification of our thoughts, which in addition must be above all a process of purification of our words? 

How can we open the world, and first of all ourselves, to the Word without entering into the silence of God from which his Word proceeds? For the purification of our words, hence, also for the purification of the words of the world, we need that silence which becomes contemplation, which introduces us into God's silence and brings us to the point where the Word, the redeeming Word, is born. 

St Thomas Aquinas, with a long tradition, says that in theology God is not the object of which we speak. This is our own normal conception. 

God, in reality, is not the object but the subject of theology. The one who speaks through theology, the speaking subject, must be God himself. And our speech and thoughts must always serve to ensure that what God says, the Word of God, is listened to and finds room in the world. 

Thus, once again we find ourselves invited to this process of forfeiting our own words, this process of purification so that our words may be nothing but the instrument through which God can speak, and hence, that he may truly be the subject and not the object of theology.

[Pope Benedict, homily, 6 October 2006]
