The Latin Mass, also known as the Tridentine Mass, is a form of the Roman Catholic Mass celebrated in Latin. It follows the liturgical guidelines established by the Council of Trent in the 16th century. This traditional form of worship emphasizes the sacredness of the rituals and the use of Latin, which was the universal language of the Church at that time. In 1969, the Second Vatican Council introduced reforms that allowed for the Mass to be celebrated in the vernacular, leading to a decline in the use of the Latin Mass. However, it has seen a resurgence in recent years, with many Catholics seeking to reconnect with this historical form of worship.
