O Come O Come Emmanuel


Beginning the Church's liturgical year, Advent (from, "ad-venire" in Latin or "to come to") is the season encompassing the four Sundays (and weekdays) leading up to the celebration of Christmas.

The Advent season is a time of preparation that directs our hearts and minds to Christ’s second coming at the end of time and also to the anniversary of the Lord’s birth on Christmas. The final days of Advent, from December 17 to December 24, focus particularly on our preparation for the celebrations of the Nativity of our Lord (Christmas).

Advent devotions including the Advent wreath, remind us of the meaning of the season.

The celebration of Mass, the Sacred Liturgy, is the center and focus of Christian life, informing and guiding our efforts to live closer to Christ. The liturgy allows us to know Christ better, and in community with others, to make him better known. In this way, we honor the mystery of Redemption throughout the year. The liturgy touches all aspects of our parish life. It teaches us the value of a deeper understanding of the scriptures, the selfless joy that comes from service to the poor, the strength we gain from community, and the peace that can come from personal prayer.

Our work is to help you find the resources you need to learn more about the liturgy. The liturgy praises God while giving thanks for his blessings. An active liturgy provides living examples of his wisdom, love, generosity and redemption – within our parishes, our community and our world.
