What was one of the main reasons for convening the Second Vatican Council?

The Second Vatican Council, which took place from 1962 to 1965, aimed to respond to the needs of the modern world and to promote a renewal within the Catholic Church. One of its primary objectives was indeed to promote liturgical reform and ecumenism.

The Council sought to make the Church's liturgical practices more accessible to the faithful, encouraging the use of vernacular languages in the Mass rather than exclusively in Latin. This change was intended to enhance participation among congregants and make the worship experience more meaningful.

Additionally, ecumenical dialogue was a significant focus during the Council. The intention was to foster better relationships with other Christian denominations and to address the issues that had historically divided them. The Council's openness to ecumenism was a transformative shift, reflecting a recognition of the importance of unity among Christians in the pursuit of shared beliefs and values.

While the authority of the Pope, the establishment of dogma concerning sin, and the role of the laity were important topics addressed during the Council, they were not the primary reason for convening. The emphasis on reforming liturgy and promoting ecumenism encapsulates the spirit of renewal and engagement with contemporary society that characterized the Council's discussions and decisions.
