This document provides information about the liturgical season of Advent, including its history, traditions, themes and purpose. Advent is a time of preparation that looks forward to both the celebration of Christ's birth at Christmas and his second coming. It encourages spiritual renewal and waiting expectantly for God to act in one's life through the "little advents" of Christ's presence in the sacraments, kindness of others, and living out one's vocation with hope, faith and love. The document explains the symbols, prayers and scripture readings of Advent and how Christians can observe this season as one of "holy waiting" to spiritually prepare for Christmas and actively await Christ's return.
