The Immaculate Conception CCC 490–493

490 To become the mother of the Savior, Mary "was enriched by God with gifts appropriate to such a role."132 The angel Gabriel at the moment of the annunciation salutes her as "full of grace".133 In fact, in order for Mary to be able to give the free assent of her faith to the announcement of her vocation, it was necessary that she be wholly borne by God's grace.

Homily for March 19, 2016. Solemnity of St. Joseph, Husband of Mary Bible Study: 2nd Samuel 7, 4 to 16. Romans 4, 13 to 22 and Matthew 1, 16 to 24. In God’s plan of salvation for mankind, it was his will that his son Jesus Christ would be born as a man, raised as a man and die as a man that humanity as a whole may be saved. This was a plan that took thousands of years to execute, a plan that even prophets who were lived centuries before Jesus spoke about.
