Our sanctification through Mary

It all comes to this, then: that you should find an easy means for obtaining from God the grace necessary to make you holy; and this means I wish to make known to you. Now, I say that to find this grace of God, we must find Mary, because:

1. Mary alone has found grace with God, both for herself and for every man in particular. The patriarchs and prophets and all the Saints of the Old Law were not able to find that grace. 

2. Mary gave being and life to the Author of all grace, and that is why she is called the Mother of Grace. 
 

3. God the Father, from Whom every perfect gift and all grace come, as from its essential source, has given all graces to Mary by giving her His Son, so that, as St. Bernard says, “With His Son and in Him, God has given His Will to Mary.” 

4. God has entrusted Mary with the keeping, the administration and distribution of all His graces, so that all His graces and gifts pass through her hands; and (according to the power she has received over them), as St. Bernard teaches, Mary gives to whom she wills, the way she wills, when she wills and as much as she wills, the graces of the Eternal Father, the virtues of Jesus Christ and the gifts of the Holy Ghost. 

5. As in the order of nature a child must have a father and a mother, so likewise in the order of grace, a true child of 

the Church must have God for his Father and Mary for his Mother; and if any one should glory in having God for his Father and 

yet has not the love of a true child for Mary, he is a deceiver, and the only father he has is the devil. 

6. Since Mary has formed Jesus Christ, the Head of the elect, it is also her office to form the members of that Head, that is to say, all true Christians; for a mother does not form the head without the members, nor the members without the head. 

Whoever, therefore, wishes to be a member of Jesus Christ, full of grace and truth, must be formed in Mary by means of the grace of Jesus Christ, which she possesses in its fullness, in order to communicate it fully to her children, the true members of 

Jesus Christ.
