In the Western Rites of Christian Churches (Roman Catholic, Anglican, Lutheran, etc.), Advent is a period of preparation, extending over four Sundays, before Christmas. To celebrate each Sunday during this period an "Advent Candle" is lighted during each Sunday Mass. Advent Wreath is used during this season of preparation to hold the Advent Candles. The word Advent comes from the Latin advenio, "to come to," and refers to the coming of Christ. This refers, first of all, to our celebration of Christ's birth at Christmas; and second, to the coming of Christ in our lives through grace.
