Ecclesia Dei

Ecclesia Dei is a papal document issued by Pope John Paul II in 1988, which aimed to address the followers of the traditional Latin Mass and reconcile them with the Roman Catholic Church. It recognized the legitimacy of the Tridentine Mass, emphasizing the importance of tradition and encouraging those who left the Church due to liturgical changes to return. The document marked a significant step in fostering dialogue and unity within the Church, acknowledging the spiritual value of the old liturgy while promoting the Church's unity and mission.
