Traditionalist Catholics are individuals who adhere to the beliefs and practices of the Roman Catholic Church prior to the reforms of the Second Vatican Council, which took place from 1962 to 1965. They often emphasize the importance of the Latin Mass, also known as the Tridentine Mass, and prefer traditional liturgical practices, rituals, and teachings. These Catholics may express concerns about modern changes in the Church, including shifts in theology, worship, and moral teachings. Many Traditionalist Catholics seek to preserve the doctrines and sacraments as they were historically understood, valuing a sense of continuity with the Church's past.
