Holy Church celebrates the saving work of Christ on prescribed days in the course of the year with sacred remembrance. Each week, on the day called the Lord’s Day, she commemorates the Resurrection of the Lord, which she also celebrates once a year in the great Paschal Solemnity, together with his blessed Passion. In fact, throughout the course of the year the Church unfolds the entire mystery of Christ and observes the birthdays of the Saints. (Sacrosanctum Concilium #102)
