Why Does St. Matthew List Joseph's Genealogy?

Dr. Constantinou discusses St. Matthew's presentation of the Nativity of the Lord. Did you ever wonder why the genealogy which is given for Christ is the ancestry of Joseph, not Mary? Why would we even know the genealogy of Jesus anyhow if He was born to a poor and apparently insignificant family? What is the importance of the Virgin birth? How do we respond to people who say that the word in Hebrew is not "virgin" but "young woman"? We will also discuss the origin of the Feast of the Nativity and explain the festal icon.
