Christianity isn’t just lived—it’s celebrated. We celebrate with the angels and saints, through historical events, and divine mysteries, each uniquely honored throughout the year with appointed festivals called “feast days.” This occurs according to the set rhythm of the liturgical calendar.
Liturgy is “the work of God,” fulfilling our duty of praise and worship to Him as His creatures. It is the divine worship offered by the Church every hour of every day, above all in the Holy Sacrifice of the Mass, followed by the Divine Office (also called the Liturgy of the Hours).
Just as the earth orbits the sun in a set pattern, so the Church revolves around the Son of God, Jesus Christ, following the pattern of the liturgical calendar.
The liturgical calendar unites the universal Church—established throughout the world—so we can celebrate and worship God together as one Body of Christ. It also synchronizes heaven and earth, joining our eternal home with our earthly pilgrimage. When we celebrate a feast day here, rest assured the angels and saints in heaven do so alongside us, though in a far more excellent way.
