How was the Second Vatican Council experienced from within? To approach the significance of that event for the Church, the image of the upper room can help: a community gathered and open to the action of the Holy Spirit, called later to go out to meet the world. The image of Pentecost was present from the preparation of the Council. In his homily on June 5, 1960, during the Solemnity of Pentecost, Saint John XXIII presented the different stages that the Council was to go through and maintained that the great conciliar event would take “shape and life in the doctrine and in the spirit of Pentecost”.
Two years later, on the 10 of June 1962, a few months before the opening of Vatican II, John XXIII returned to the image of Pentecost. In his homily that day, he described the mission of the Church based on the words of Jesus to the apostles: “you will be my witnesses (…) to the ends of the earth”. He also presented that celebration as a foretaste of what would happen in the Vatican on October 11, when the Council would begin.
In that same homily, Pope John XXIII said that Vatican II should express Christ as “light and wisdom, as guidance and encouragement, as comfort” for human life. He also related the Council to the new circumstances of humanity, in a context of scientific advances, research, and technical development. The expression “comes out of the closed confines of its cenacles”, appears when Pope John XXIII describes the dynamism of the Church driven by Pentecost.
Church that learns to look at its time
On October 11, 1962, when solemnly inaugurating Vatican II, Saint John XXIII explained that this assembly should present the Magisterium of the Church taking into account “the deviations, the demands, and the circumstances of the contemporary age.” After three years of preparation, the Pope hoped that the Church could look “fearlessly” towards the future and find new energies for its mission. In that same speech, Saint John XXIII questioned the interpretations that saw only decay and difficulties in contemporary times. In the face of the so-called “prophets of calamities,” he maintained that the Church should also recognize the possibilities that the historical moment it was living offered.
This attitude was later reflected in Gaudium et spes, the pastoral Constitution on the Church in the modern world. The document begins by recognizing that “the joys and hopes, the sorrows and anxieties” of the people of its time are also those of the disciples of Christ, and affirms that the Church feels connected to humanity and its history. The conciliar document also states that the Church has the duty to “scrutinize the signs of the times” and interpret them in the light of the Gospel. This attitude was meant to allow it to respond to the enduring questions of humanity and to the new circumstances of each era.
The perspective did not imply abandoning the Christian tradition. In the opening speech, John XXIII distinguished between the content of Christian doctrine and the forms in which it can be expressed. The Pope maintained that the doctrine should be preserved in its integrity, but that its presentation should take into account contemporary ways of thinking.
Faith is not lived with one's back to life
The Council presented faith in relation to the different dimensions of human existence. Gaudium et spes dedicated specific chapters to the dignity of the person, marriage and family, culture, economic and social life, the political community, and the promotion of peace.
The concern of the Church, therefore, was not limited to internal issues. The conciliar document states that the Christian community is called to share the joys and sufferings of humanity and to engage in dialogue with the world in which it lives. This perspective helps to understand one of the shifts in perspective associated with Vatican II: the Church does not renounce its mission nor their tradition, but recognizes that to announce the Gospel it must know the realities in which people live.
In the opening of the Council, Saint John XXIII expressed precisely this concern when speaking of the “new conditions and ways of life introduced in the current world.” The challenge was to present the teaching of the Church in a way that could respond to the circumstances of its time.
The dream of a reconciled Church and a united world
The search for unity was another of the important dimensions of Vatican II. In his inaugural speech, the Pontiff pointed out among the expected fruits of the Council the progress towards the unity of Christians. This concern would materialize during the development of the Council in the Decree Unitatis redintegratio, approved in 1964.
Unitatis redintegratio states that promoting the restoration of unity among all Christians is one of the main purposes of Vatican II. The document proposes, among other paths, the dialogue among Christians, the prayer and collaboration for the common good.
The Council also opened a new space for relations with non-Christian religions. In Nostra aetate, approved in 1965, the Church indicates that it considers with greater attention its relations with other religions and highlights what can lead to solidarity and encounter among peoples.
In this way, the unity sought by the Council was not limited to relationships within the Catholic Church. It also included the approach to other Christians and a new attitude of dialogue and respect towards non-Christian religions.
From the upper room to the paths of the world
Seen from today, Vatican II can be understood as a moment when the Church decided to face the transformations of its time. It was not about abandoning its roots, but about asking how to live and communicate the Gospel in a changing world.
The words of Saint John XXIII during the preparation and opening of the Council allow us to follow this process. Vatican II constitutes an important precedent for understanding the synodal path. Synodality today takes up questions that were already present in the conciliar impulse: how to listen to reality, how to discern the signs of the times and how to walk together in mission. Gaudium et spes offers a primary reference for this attitude of listening by stating that the Church must scrutinize the signs of the times and interpret them in the light of the Gospel.
The “New Pentecost” associated with Vatican II can be read as an invitation not to remain enclosed. A Church that preserves its identity, but goes out to meet, listens, dialogues, and seeks to recognize the action of the Spirit in history.
