From today's Mass readings, for this feast of Candlemas:
Behold, I will send My messenger, and he shall prepare the way before My face; and the Lord, whom you seek, shall suddenly come to His Temple, even the Messenger of the Covenant, in whom you delight. Behold, He shall come, says the LORD of hosts. But who may endure the day of His coming? And who shall stand when He appears? For He is like a refiner's fire, and like fuller's soap. He shall sit refining and purifying silver, and He shall purify the sons of Levi, and refining them like gold and silver, that they may offer to the LORD an offering in righteousness. Then the offering of Judah and Jerusalem will please the Lord, as in the days of old, and as in years gone by.
