Erigena writes in the "Expositions": "Man was not created for Scripture, of which he would not have had necessity if he wouldn't have sinned, but rather Scripture -- interwoven with doctrine and symbols -- has been given to man. Thanks to it, in fact, our rational nature can introduce itself into the secrets of the authentic pure contemplation of God (II, PL 122, col 146C). The word of sacred Scripture purifies our rather blind reason and helps us to return to the memory of what we, as image of God, carry in our hearts, unfortunately violated by sin.
From here, some hermeneutical consequences are derived regarding the way to interpret Scripture, which can indicate still today the just path for a correct reading of sacred Scripture. It is a matter, in fact, of discovering the meaning hidden in the sacred text and this supposes a particular interior exercise thanks to which reason opens itself to the sure path leading to truth. This exercise consists in cultivating a constant readiness for conversion. To arrive deeply to the vision of the text, it is necessary to advance simultaneously in the conversion of the heart and in the conceptual analysis of the biblical page, whether it be of cosmic, historical or doctrinal character. Only thanks to the constant purification, as much of the eyes of the heart as of the eyes of the mind, can the exact understanding be achieved.
This arduous path, demanding and exciting, made up of continuous conquests and relativations of human knowledge, brings the intelligent creature toward the threshold of the divine Mystery, where all notions verify their own weakness and incapableness and lead, therefore, to going beyond -- with the simple, free and sweet force of the truth -- all that is continuously reached. The adoring and silent recognition of the Mystery, which flows into unifying communion, is revealed therefore as the only path for a relationship with the truth that is at the same time the most intimate possible and the most scrupulously respectful of the otherness.
