A Goodreads user asked:
..."We finally discover the answer to the question with which we started: After the tearing of the Temple curtain and the opening up of the heart of God in the pierced heart of the Crucified, do we still need sacred space, sacred time, mediating symbols?" (Question/Answer found on page 60-61 in chapter entitled "Relationship of Liturgy to Time and Space")
booklady yes, we do need them, precisely so that, through the "image", through the sign, we learn to see the openness of heaven. We need them to give us the capacity to know the mystery of God in the pierced heart of the Crucified.
