Is There a Mediator with the "One Mediator Between God and Man"?

This spiritual gem is taken from "True Devotion" by St. Louis De Montfort:

83. It is more perfect, because it is more humble, not to approach God of ourselves without taking a mediator. Our nature, as I have just shown, is so corrupted that if we rely on our own works, efforts and preparations in order to reach God and please Him, it is certain that our good works will be defiled or be of little weight before God in inducing Him to unite Himself to us and to hear us. It is not without reason that God has given us mediators with His Majesty. He has seen our unworthiness and our incapacity; He has had pity on us; and in order to give us access to His mercies, He has provided us with powerful intercessors with His Grandeur, so that to neglect these mediators, and to draw near to His Holiness directly, and without any recommendation, is to fail in humility. It is to fail in respect toward God, so high and so holy. It is to make less account of that King of Kings than we should make of a king or prince of this earth, whom we would not willingly approach without some friend to speak for us.

84. Our Lord is our advocate and Mediator of redemption with God the Father. It is through Him that we ought to pray, in union with the whole Church, Triumphant and Militant. It is through Him that we have access to the Majesty of the Father, before whom we ought never to appear except sustained and clothed with the merits of His Son, just as the young Jacob came before his father Isaac in the skins of the kids to receive his blessing.

85. But have we not need of a mediator with the Mediator Himself? Is our purity great enough to unite us directly to Him, and by ourselves? Is He not God, in all things equal to His Father, and consequently the Holy of Holies, as worthy of respect as His Father? If through His infinite charity He has made Himself our bail and our Mediator with God His Father, in order to appease Him and to pay Him what we owed Him, are we, on that account, to have less respect and less fear for His Majesty and His Sanctity?

Let us say boldly with St. Bernard (2) that we have need of a mediator with the Mediator Himself, and that it is the divine Mary who is the most capable of filling that charitable office. It was through her that Jesus Christ came to us, and it is through her that we must go to Him. If we fear to go directly to Jesus Christ, our God, whether because of His infinite greatness or because of our vileness or because of our sins, let us boldly implore the aid and intercession of Mary, our Mother. She is good, she is tender, she has nothing in her austere and forbidding, nothing too sublime and too brilliant. In seeing her, we see our pure nature. She is not the sun, which by the brightness of its rays blinds us because of our weakness; but she is fair and gentle as the moon (Cant. 6:9), which receives the light of the sun, and tempers it to make it more suitable to our capacity. She is so charitable that she repels none of those who ask her intercession, no matter how great sinners they have been; for, as the saints say, never has it been heard since the world was the world that anyone has confidently and perseveringly had recourse to our Blessed Lady and yet has been repelled. (3)

She is so powerful that none of her petitions has ever been refused. She has but to show herself before her Son to pray to Him, and straightaway He grants her desires, straightaway He receives her prayers. He is always lovingly vanquished by the prayers of His dearest Mother, who bore Him and nourished Him. (4)

86. All this is taken from St. Bernard and St. Bonaventure, so that according to them, we have three steps to mount to go to God: the first, which is nearest to us and the most suited to our capacity, is Mary; the second is Jesus Christ; and the third is God the Father. To go to Jesus, we must go to Mary; she is our mediatrix of intercession. To go to God the Father, we must go to Jesus; for He is our Mediator of redemption. Now the devotion that I am about to bring forward observes this order perfectly.
