About Martin Buber:
The foundations of Buber's religion philsophy lie in his Chassidic work and his philosopy of dialogue. The basis of belief is the relation between man and God, the relation to the eternal Thou. In an unparalleled consistent way he accomplishes the anthropological turn-about in theology towards the human being: following the dialogical existence of man, there is no statement about God which does not at the same time state something about man. For Buber, the biblical history of belief of Israel is a living tradition, a dialogical history between God and man: from calling Abraham out of his environment, the covenant at Mount Sinai up to the prophets, a dialogical history which demands anyone who joins it.
The basis for all statement about faith is the dialogical relation of trust, not the belief in dogmatic contents, as he views in Christian theology: "One can believe that God is and live in his back, he who trusts him lives in his face." (Two Types of Faith). "Trust is proving trust in the fullness of life in spite of the experienced course of the world."
