14 In the faith of Israel we also encounter the figure of Moses, the mediator. The people may not see the face of God; it is Moses who speaks to YHWH on the mountain and then tells the others of the Lord’s will. With this presence of a mediator in its midst, Israel learns to journey together in unity. The individual’s act of faith finds its place within a community, within the common "we" of the people who, in faith, are like a single person — "my first-born son", as God would describe all of Israel (cf. Ex 4:22). Here mediation is not an obstacle, but an opening: through our encounter with others, our gaze rises to a truth greater than ourselves. Rousseau once lamented that he could not see God for himself: "How many people stand between God and me!" … "Is it really so simple and natural that God would have sought out Moses in order to speak to Jean Jacques Rousseau?" On the basis of an individualistic and narrow conception of knowledge one cannot appreciate the significance of mediation, this capacity to participate in the vision of another, this shared knowledge which is the knowledge proper to love. Faith is God’s free gift, which calls for humility and the courage to trust and to entrust; it enables us to see the luminous path leading to the encounter of God and humanity: the history of salvation.
