Second, the Lord, Alpha and Omega, will come to judge the living and the dead in the Second Coming. Third, the Redeemer comes to us in grace. He speaks to us in our consciences, he comes to us in the Eucharist and in the Word of God proclaimed. He arrives in the person of the begger, the needy, the suffering, the oppressed. We must be ready to receive and welcome Him when He comes, however He comes.
Advent is a time of joy tinged with penance.
Joy, because we can imagine nothing more sweet than the Christ Child and His Mother Mary's bliss at His coming to light. Penance because we must strive to be properly disposed to receive so great a gift of His presence. In the millennial tradition of the Church, we faithful have done penance before great feasts. Christmas and Easter each have their penitential seasons in anticipation, Advent and Lent. The liturgical color used in the Latin Church for the liturgy during both Advent and Lent is purple, a sign of penance.
