What does the book of Luke 11:27-28 mean; and does it undermine Roman Catholic theology?

In the book of Luke 11:27-28, we see a point in Jesus’ ministry where he is famed throughout the land of Roman occupied Judea. One woman declares to Jesus that his mother, Mary, must be Holy. Jesus replies to her that rather than Mary, those that hear God’s commandments and keep it are the ones who are blessed. The word “rather,” in these verses derive from the Greek word, “μενοῦνγε,” or “menounge,” which means the same as “rather” or “on the contrary.” To me this verse states that God, and his son, Jesus would that people believe in and keep the commandments rather than assume that Jesus parental or familial relations are the factors that define holiness. In the book of Mark 3:34–35, we see the passage: And he, Jesus, looked round about on them which sat about him, and said, Behold my mother and my brethren! For whosoever shall do the will of God, the same is my brother, and my sister, and mother. There are compelling passages, namely in the Book of Revelation chapter 12 however, that Catholics believe uphold the divinity of Mary Mother of Jesus. In contrast, I, in my readings of the book of Revelation have identified this chapter in Revelation to be a representation of Earth, and mankind's dealings with Satan. The woman in this chapter of Revelation could however be very easily interpreted to be Mary, the mother of Christ, and the trials and tribulations she faced in relation to the birth of Jesus Christ. Canonization, particularly in the Catholic cultural tradition holds that their are Christians that live lives and perform works that surpass the natural tendencies of man to a degree that mandates their sainthood. I hold that the Bible verses quoted in this essay declare saints to be those that keep God’s commandments to the best of their ability in relation to the scriptures. Some would argue however that Sainthood is a tradition in the Catholic church, and that the Saints themselves may or may be considered divine, or deities by adherents of the Catholic faith.
