In Christian art we can contemplate the way of love that the Lord reveals to us and that he invites us to follow. In fact, in the earliest times "in the arrangement of Christian sacred buildings [...] it became customary to depict the Lord returning as a king -- the symbol of hope –at the east end; while the west wall normally portrayed the Last Judgment as a symbol of our responsibility for our lives" (Spe salvi, 41): hope in the infinite love of God and commitment to order our life according to God's love. When we contemplate the depiction of Jesus inspired by the New Testament –as an ancient council teaches- we are led to "understand [...] the sublimity and the humiliation of the Word of God and [...] to recall his life in the flesh, his passion and salvific death, and the redemption that thus came to the world" (Council of Trullo [ca. 691 or 692], canon 82). "Yes, we need it, precisely to [...] become capable of recognizing in the pierced heart of the Crucified the mystery of God"  ■ J. Ratzinger, Teologia della liturgia: La fondazione sacramentale dell'esistenza cristiana, LEV 2010, p. 69
