"To refuse this silence filled with confident awe and adoration is to refuse God the freedom to capture us by His love and His presence. Sacred silence is therefore the place where we can encounter God, because we come to Him with the proper attitude of a human being who trembles and stands at a distance while hoping confidently. We priests must relearn the filial fear of God and the sacral character of our relations with Him. We must relearn to tremble with astonishment before the Holiness of God and the unprecedented grace of our priesthood.
Silence teaches us a major rule of the spiritual life: familiarity does not foster intimacy; on the contrary, a proper distance is a condition for communion. It is by way of adoration that humanity walks toward love. Sacred silence opens the way to mystical silence, full of loving intimacy. Under the yoke of secular reason, we have forgotten that the sacred and worship are the only entrances to the spiritual life. Therefore I do not hesitate to declare that sacred silence is a cardinal law of all liturgical celebration."
