The Church punctuates the liturgical year by celebrating various events important to the mystery of our salvation. During the course of the liturgical year, we celebrate the whole mystery of Christ, from His incarnation and birth to His ascension, to Pentecost and the founding of the Church, and finally to the second coming of Christ in judgment on the Solemnity of Christ the King. On Sundays, in particular, we commemorate the Resurrection, when our Lord triumphed over sin and death. In a special way, the Church also honors our Blessed Mother, marking those special events of her participation in the mystery of salvation. Finally, the Church also commemorates the memorial days of saints, who, through their lives, bring to the minds of the faithful the call to holiness. Summary by: CatholicStraightAnswers.com
