Today begins the O Antiphons! It’s when the prayers of the Church change to more intently prepare for the celebration of the birth of Christ. O Sapientia is the antiphon for today and it celebrates Jesus as Wisdom: Sirach (or Ecclesiasticus in old Bibles) 24:2; Wisdom 8:1
In the assembly of the Most High she opens her mouth, in the presence of his host she tells of her glory
Indeed, she spans the world from end to end mightily and governs all things well.
