The works
that Fr. Félix Granda made for the Sanctuary of the Great Promise include the main and lateral altarpieces. In the main altarpiece, the reliefs are brilliantly inserted into the masonry of an old altarpiece. Granda used them to create a rich iconographic program, focused on the theology of the Sacred Heart of Jesus. The upper scenes establish a dialog between the Old and the New Testament. Hence, Melchizedek makes his sacrifice of wine and bread in front of the altar of the Last Supper, as the prefiguration of the Eucharist. In the other panel, the appearance of the Savior to St. Thomas refers directly to the epiphany of the mystery of the Sacred Heart. In the foreground, Zechariah is holding a phylactery with his prophecy: “They will look on me whom they have pierced”.To the left, there is a large polychrome wooden altarpiece, dedicated to the Virgin of the Pillar. On the opposite side of the transept, we find the altarpiece dedicated to Jesus Christ, King of the Martyrs, a solemn and elegant architectural composition made in marble and bronze around a small altarpiece from the 16th century. In addition to these works, Félix Granda designed and executed other elements for this church, such as the sculptural lamps of the Blessed Sacrament as well as all the liturgical gold and silverware.
