Who is Mary the Mother of God from Catechism of the Catholic Church and what is their importance?

This is Mary, the Virgin Mother of Lord Jesus. She comes up during the Profession of Faith in the Catechism. She is considered most remarkable for having been free from sin throughout her entire life. Another incredible truth about her is that she was offered the role of the Son of God's mother and she accepted it freely. She is known to have miraculously conceived in a means that is "twofold." On the level of spirit she did not conceive without a father, but the father was not an incarnate mortal man. In the case of Mary, she became pregnant without the loss of her virginity thanks to and in accordance with what she was told would happen by an angel.
