From an experience of conversation with Cláudio Pastro, the author proposes a re-reading of the university chapel of Catholic University of Pernambuco, renovated by the artist, from the perspective of a less discursive and more iconographic theology. In the first part, the article narrates the aspects that made it possible, from a variety of discussions, to propose a renovation of this space of worship and prayer in the light of the Second Vatican Council, attesting how much the issue of image is fundamental in Christian ethics, not delegating to the aesthetics a debate only about beauty and its meaning. The Christian building brings together a very eloquent universe, in which the visualization of what is celebrated is revealed. In the second part, we move from the pedagogy of the renovated space to a mystagogy, thanks to the symbolism of liturgical monuments and other elements of sacred art, icons of the Church and Christian life. Finally, by way of conclusion, an open synthesis, rehearsing new interpretations of the Jesuit tradition, of Christianity and of liturgical space itself.
