Preposterous. How can she be when Jesus says He is the provision for sin and no one comes to the Father but by Him?
This is just silly and dis-credits your cause.
[F]or twenty years Our Lord appeared to Gertrude at least once every day...Very often He urged her, as His Church urges us all, to come to Him through Mary.
When Gertrude asked Him what she could do to please Him more, Jesus answered: "Behold My Mother. Endeavor to praise her worthily." In the early years of her conversation, Our Lord said to the Saint: "I give thee My sweet Mother as thy Protectress. I confide thee to her care." And when during a trial Gertrude called upon Jesus to help her, He replied: "I have given thee My own most merciful Mother for thine, and it is through her that I will dispense My graces to thee...."
Once, as the Saint was praying to Jesus to offer His Mother something to make up for her own lack of devotion toward the Blessed Virgin, Our Lord arose, and offering Mary His Sacred Heart, He said: "Most loving Mother, behold My Heart. I offer it to thee with all that divine and eternal Love which prompted Me to choose thee for My Mother. In this Heart I offer thee all that filial affection of which I gave thee so many tokens on earth, when thou didst nourish and carry Me as a little child in thy arms. In this Heart I offer thee that faithful love which kept Me near thee all My mortal life, obedient to thy wishes, as any other son to his mother. I offer thee especially that love which on the Cross made Me in a measure forget My tortures to compassionate thy bitter desolation and to leave thee in My place a guardian and son. And lastly, behold in My Heart the love which prompted Me to exalt thee in thy blessed Assumption far above the Saints and Angels and to crown thee Queen of Heaven and earth." --from Saints Who Saw Mary
