Readings for Celebrating Advent

3 Look, I am sending my messenger who will clear the path before me;
        suddenly the Lord whom you are seeking will come to his temple.
        The messenger of the covenant in whom you take delight is coming,
says the Lord of heavenly forces.
² Who can endure the day of his coming?
        Who can withstand his appearance?
He is like the refiner’s fire or the cleaner’s soap.
³ He will sit as a refiner and a purifier of silver.
        He will purify the Levites
            and refine them like gold and silver.
            They will belong to the Lord,
                presenting a righteous offering.
