Feast of St Sebastian the Martyr & His Companions
THE FATHER exclaimed: This is my beloved Son, in Whom I am well pleased; heed Him. Thus He spoke of the Son, Who is undivided from the glory of the Divinity. For the Father and the Son together with the Holy Spirit are one nature, one force, one essence and one kingdom.
And Mary was called the Mother of God by His Son in the flesh, Who was undivided from the glory of His Divinity. For one is God, Who has appeared to the world in the flesh.
His glory proclaimed His divine nature which is from the Father, and His body proclaimed His human nature which was from Mary; both of His natures converged and were united in a single hypostasis.
He was the Only-Begotten of the Father and also the Only-Begotten of Mary. And he who divides the hypostasis in Him will also be separated from His kingdom, and he who conjoins His natures will be deprived of the life that is of Him.
He who denies that Mary gave birth to God will not see the glory of His Divinity, and he who denies that He was clothed in sinless flesh will receive neither salvation nor the life which was granted through His body.
His very deeds give witness and His divine strength teach the contemptuous that He is true God. And His sufferings give proof that He is true man.
—St Ephraim the Syrian, A Spiritual Psalter
