Fifth Day within the Octave of the Nativity of the Lord

He is the image of the invisible God, the first-born of every creature. For in him was created everything in heaven and on earth, visible and invisible, whether thrones, or dominations, or principalities, or powers. All things were created through him and in him. And he is before all, and in him all things continue. And he is the head of his body, the Church. He is the beginning, the first-born from the dead, so that in all things he may hold primacy. For the Father is well-pleased that all fullness reside in him, and that, through him, all things be reconciled to himself, making peace through the blood of his cross, for the things that are on earth, as well as the things that are in heaven.
