The day of the Nativity of the Mother of God is a day of universal joy, because through the Mother of God, the entire human race was renewed, and the sorrow of the first mother, Eve, was transformed into joy.

O Mother of God! If I place my confidence in thee, I shall be saved; if I am under thy protection, I have nothing to fear; for the fact of being thy client is a possession of a certainty of salvation which God grants only to those whom He intends to save.

And all that is therein; Invisible and visible, Their notes let all things blend, For Christ the Lord is risen. Our joy that hath no end.

Christ sits in the body at the right hand of God the Father, but we do not hold that the right hand of the Father is actual place. For how could He that is uncircumscribed have a right hand limited by place? But we understand the right hand of the Father to be the glory and honor of the Godhead in which the Son of God, Who existed as God before the ages, and is of like essence to the Father, and in the end became flesh, has a seat in the body, His flesh sharing in the glory. For He along with His flesh is adored with one adoration by all creation.

Think of the Father as a spring of life begetting the Son like a river and the Holy Ghost like a sea, for the spring and the river and sea are all one nature. Think of the Father as a root, and of the Son as a branch, and the Spirit as a fruit, for the substance in these three is one. The Father is a sun with the Son as rays and the Holy Ghost as heat.
