After speaking of the Church, her origin, mission, and destiny, we can find no better way to conclude, than by looking to Mary. In her we contemplate what the Church already is in her mystery on her own "pilgrimage of faith," and what she will be in the homeland at the end of her journey. There, "in the glory of the Most Holy and Undivided Trinity," "in the communion of all the saints," the Church is awaited by the one she venerates as Mother of her Lord and as her own mother.
Catechism of the Catholic Church
The Profession of Faith, Part I, § 972.
Remember Elizabeth (house of God) represents the Church, when Mary came to visit her and help her in her latter days of pregnancy to give birth to John the Baptist. Remember what Elizabeth says?
And it came about that Elizabeth heard Mary's greeting, the baby leaped in her womb; and Elizabeth was filled with the Holy Spirit. And she cried out with a loud voice, and said, "Blessed among women are you, and blessed is the fruit of your womb! And how has it happened to me, that the mother of my Lord should come to me?" [Luke 1:41-43; NASB]
For those of you who have a 'hard time' with Mary being the Mother of God, please read, and think, reason, consider and like Mary, PONDER in your hearts this:
Mary, The Mother of My Lord
