Leo XIV celebrates the centenary of the Pontifical Institute of Christian Archaeology, defining the study of early Christian monuments as a tool for ecclesial unity and European roots
Yesterday 11 December, in the Clementine Hall of the Vatican Apostolic Palace, Pope Leo Pontifical Institute of Christian Archaeology on the occasion of the centenary of its foundation. An anniversary that the Pontiff celebrated by publishing a Apostolic letter dedicated to the importance of Christian archaeology, a discipline that studies the monuments of the first centuries of Christianity.
Exactly one hundred years ago, Pius XI established the Institute with the Motu proprio The primitive cemeteriesentrusting him with the mission of training “willing young people from every country and nation” in the scientific study of Christian antiquities. Alongside the catacombs, the papal document mentioned the Roman basilicas with their mosaics, inscriptions, sculptures and liturgical furnishings, recognizing the legacy of pioneers such as Giovanni Battista de Rossi And Antonio Bosio.
The scientific dignity of a discipline
In his speech, Leo XIV claimed the specificity ofChristian archaeologyequipped with a own “epistemological status” defined by precise chronological, historical and thematic coordinates. An autonomous discipline which, the Pope observes, in some contexts is mistakenly absorbed into medieval archaeology, thus losing its scientific identity.
Christian archeology is not simply the study of ancient finds, but exploration of the roots of faith through material testimonies that tell the life of the first believing communities.
Common roots for a united Church
The heart of the pontifical message lies in the ecumenical dimension of Christian archaeology. This discipline, explains the Pope, concerns “the historical period of the united Church”, when confessional divisions had not yet fragmented the ecclesial body. For this reason, the study of early Christian monuments becomes “a valid tool for ecumenism”.
The different Christian confessions can recognize their shared roots in those testimoniesfueling “the aspiration for full communion”. Leo XIV recalled having personally observed this potential during the recent apostolic journey to İznik, ancient Nicaeawhere he commemorated the first Ecumenical Council together with representatives of other Churches and ecclesial communities. It is no coincidence that the Pontifical Institute dedicated a day of study to this theme, in collaboration with the Dicastery for Evangelizationan initiative welcomed with particular favor by the Pontiff.
Cultural diplomacy
In an era marked by divisions and stereotypes, Pope Leo XIV proposes culture as a diplomatic tool capable of building bridges. The study of Christian archeology represents that “diplomacy of culture” so necessary today, capable of drawing on literary and monumental sources to evoke a common identity.
As underlined in the Apostolic Letter, the Institute is ideally placed between two Jubilees: that of peace in 1925 and that of hope currently underway. A time span that embraces a century of research at the service of memory and communion.
The Christian roots of Europe
The Pope’s speech ends with a reference to the words of Saint John Paul II on the communes Christian roots of European nations. The literary and monumental sources studied by Christian archeology are not simple testimonies of the past, but represent the “roots” of European society and nations.
«Europe needs Christ and the Gospel, because here are the roots of all its peoples», stated the Polish saint. Words that Leo XIV made his own, remembering how the protection of sacred heritage is not just material conservation, but the preservation of the cultural and spiritual identity of a continent.
