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.
