January 1st: Dom Gueranger on First Vespers of The Circumcision of Our Lord Pt. I

"Today, the Son of Man is to be circumcised; this first sacrfice of his innocent Flesh must honour this eigth day of his mortal life. Today, also, a Name is to be given him - the Name will be 'Jesus', and it means 'Saviour'. So that, Mysteries abound on this day: let us not pass one of them over, but honour them with all possible devotion and love................

"There is another object, that shares the love and devotion of the Faithful, on this great Solemnity. This object is Mary, the Mother of God. The Church celebrates, today, the august prerogative of this divine Maternity, which was conferred on a mere creature, and which made her the co-operatrix with Jesus in the great work of man's salvation."
