This is the Optional Memorial of the Dedication of the Church of Our Lady of the Snow (St. Mary Major). Here is Saint Mary Major, from last November, looking out from the church and upwards.
The Catholic calendar is filled with wonderful feast days, like the one today! From a discourse by Saint Andrew of Crete, bishop:
Justly, then, do we celebrate this mystery since it signifies for us a double grace. We are led toward the truth, and we are led away from our condition of slavery to the letter of the law. How can this be? Darkness yields before the coming of the light, and grace exchanges legalism for freedom. But midway between the two stands today’s mystery, at the frontier where types and symbols give way to reality, and the old is replaced by the new. Therefore, let all creation sing and dance and unite to make worthy contribution to the celebration of this day. Let there be one common festival for saints in heaven and men on earth. Let everything, mundane things and those above, join in festive celebration. Today this created world is raised to the dignity of a holy place for him who made all things. The creature is newly prepared to be a divine dwelling place for the Creator.
“Rejoicing, I will rejoice in the Lord, and my soul shall be joyful in my God. He has clothed me with the garment of salvation, and with the robe of justice he has wrapped me about, as a bride adorned with her jewels” (Is 61:10).
