Some may say, because they are both German in origin. But it is not that simple. “Maria Als
  Knotenlöserin in English “Mary Untier of Knots” was an expression that came from an event in
  which the venerable father Jacob Rem J.P.,plays a role in the true history of the Virgin Mary
  Untier of Knots. In the story the noble Wolfgang Langenmantel being on the verge of a divorce,
  visits with the venerable priest at Ingolstadt for a period of 28 days where they prayed for his
  marriage before the image of Our Lady of the snows. During these days of prayer, father Rem
  «in a solemn ritual act, elevates the matrimonial ribbon untying each of the knots. On day 28
  the ribbon became smooth, white and pure as it was on the first day of the wedding vows
  taken by Wolfgang and Sophie Inmoff», and this is how the marriage was able to continue. 
  From then on father Rem became part of the history of the Image of the Virgin Mary Untier of
  Knots and as influence to the ancient and noble family of the Langenmantels.

  The Cathedral “Liebfrauenmunster” , was constructed almost 200 years ago by duke Gebartete
  and enriched with gold brought by him from France. Already in function was the most important
  University of south Germany. In 1595 on the south side and after the division of the Marian
  congregation “Mayor” and “Minor” the Jesuit Priest made their  chapel in the convent of Saint
  Ignatious with father Jacob Rem as the Rector. Jacob Rem was born in June 1546 in Bregenz
  (Austria) by the Constanza lake in the limits of the Swiss Cantons. He passed away on Friday
  12th of October ( date of his feast day) 1618 at Ingolstadt, he is buried in this same Cathedral.
  When he was 20(1566), he joined the Jesuit order in Rome. He worked in Munich Dilligen, and
  lastly at Ingolstadt where he was particularly dedicated to religious education. The oratory of
  the congregation had a copy of the Image of “Our Lady of the Snows”, which gave origin to our
  own and others, as we will see later on. This Image painted in Oil, was a very rare style for that
  period and captivated anyone who would see it.

  On Friday april 16th 1604, Father Jakob Rem played a role in a “Marian Illumination” event that made
  him famous. As he was kneeling in the chapel of the colloquium , when he finished the rosary and
  sang the Laurentian Letanies. We are told that he was above the earth “covered with wings” (which
  he declares to question), The Mother of God had appeared to him and told him : 
  «The title of Mater Admirabilis, is especially dear to me», for which Father Jakob Rem moves to the
   left and repeats this title two more times. This is how the title of “ Thrice Admirable” originated.

  The devotion of this merciful painting of the “Dreimal wunderbaren Mutter” ( Mother Thrice admirable)
  stayed at the Jesuit college in the memories of the priest and of Jakob Rem. It has stayed in the
  memory and in the treasures of the Cathedral. This Marian event where Jakob Rem was chosen to
  play a role, projects itself as motivation for our times. After the expulsion of the Jesuit orders in 1773
  from the Spanish domains, the painting of the Ignatious convent was returned and transferred to 
  Mary of the Victories Church and was published by the university , returning after the taken over of
  the Landshut Bavaria in 1879 by king Ludwig II and was enthroned solemnly in the cathedral in the
  year 1881. 

  Since 1881 solemn manifestations began in the cathedrals. During the war in 1942 she
  was placed under the ownership of the State(Eichstatter) The Bishop of the State Michael Rackl
  placed the whole diocese under the protection of the “ Thrice admirable” and lifted the ownership of
  the Diocese as it was before. This gives proof to the holy character in which they based themselves
  to request the canonization of father Jakob Rem. Since the process of canonization subsist until
  today and the authorities from Rome have not expedited the process, I wish to manifest that the
  oratory was visited by students and priest science professors, such as mathematics, physics,
  chemist and astronomy. With this I wish to point out that the spirit of mysticism did not prevail in
  excess.

  The Title of “Mater Ter Admirabilis” (Dreimal Wunderbaren Mutter in german or Mother Thrice
  Admirable in English), was taken by the founder, the movement was created and directed by
  father Josef Kentenich. It is evident that Father Kentenich followed the footsteps of the Venerable
  Jacob Rem”. Josef Kentenich was born in 1885 in vallendar  (Middle of west Germany between
  Frankfurt and Colonia) over the Rihn river. He was ordained at a very young age in 1910, he was
  a Latin teacher in the seminary of the Pallottinos Priest in Schöenstatt a small village of that
  territory.
  Now a days the city of vallendar is a strong and modern city contrasting with some buildings
  such as the church of St. Peter and Marcelino, the chapel of St. marine with the tower at the
  bottom of the Wasserburg castle and the house of union of the Palatinos priest joined to the
  Schoenstatt editorials.

  Father Kentenich was named the spiritual director of the seminarians,of their formation as youth
  and for their preparation for the times and the world that would come to schoenstatt. “ To form 
  new men in a new community” under the protection of Mary, we wish to educate ourselves to be
  able to become righteous , free and priestly characters”, In 1912 and with this words father 
  Kentenich would expressed himself to his pupils as he began to give the basics of what is now
  called “ Marian Congregation”

  We are told that he gathered the seminarians on Sunday October 1914 in an old abandoned
  chapel used to store tools for the seminary dedicated to St. Micheal the Archangel (Patron of
  Bavaria). He expressed the following : “ Without a doubt, there is no other accomplishment as
  great as this apostolic action and to leave our successors with the precious inheritance of
  inducing our Sovereign Lady to erect her throne here in a very special way, so that she may
  pour out her treasures and work miracles of graces”…

  On that day 1914, a few months after Germany declared war on Russia (August 1st 1914) and
  while Europe was preparing for one of the most catastrophic wars, the Schöenstatt Movement 
  is formed.
  A few months later the image of the Virgin Mary as the Mother of God was enthroned in the
  chapel; this image was a lithograph ( copy right series) from a painting by swiss Luigi Crosio
  that had the title “ Refuge of Sinners”
  The venerable father Kentenich, following the historical footsteps of another saint of the German
  church, Father Jakob Rem of the University of Ingolstadt, who 300 years before had already
  founded the first marian congregations and who was the one that gave the title of:
  “Dreimal Wunderbaren Mutter”, ( Mater Ter Admirabilis), Mother Thrice Admirable. Since this 
  date on the 18th members of the Schöenstatt Movement renew their commitment of Love to this
  apostolat.

  Both world wars marked he Schöenstatt apostolate, the first one marked its founding and the
  second one was to face grave problems . The Schöenstatt devotion has the particularity of being
  articulate, not simply because of the veneration of the image. The shrine and the devotion to Mary
  as guide for vocations are implicit, they manifest the Kentenich spirituality such as : “To Christ
  with Mary, in the Holy Spirit to the Father”. The Fatherly spirituality of God the Father is the
  objective followed by father Kentenich, millions of children were left without parents during the
  second world war. We are told that father Kentenich who was an orphan(without a father) would
  recognized this as the need that changed his life. During world war I, one of the most active
  members of the movement and seminarian Josef Engling loses his life at Cambrai France.

  During world war II en 1941 Father Kentenich is taken prisoner by the Gestapo and retained for
  a month in the prison of Koblenz.  He suffered prison in the concentration camp of Dachau. In
  prison , like the apostle Paul, he continued writing the main books for the Schöenstatt fraternity.
  We are told that a prisoner from “schöenstatt” by the name of Carl Leisner was ordained a priest
  at the same concentration camp. Pope John Paul II beatified him in 1996.

  When he was in Chile at the Bellavista Shrine, venerable Kentenich wrote a very extensive letter
  where he expresses strong criticism to the Church thru the person of the Bishop of the diocese
  of Treveris to whom the Schöenstatt movement depended on. It is not long before the replica of
  the many priest and committed laity of the church have suffered before the council of Vatican II.

  Father Kentenich is removed from the Order and is sent to immigrate to the United States to a
  parish in Milwaukee where he tastes the bitter chalice after being a person that gave all his
  existence for vocations to the service of the Church made of the faithful and the ordained.
  In one of the last meetings of the Council, father Kentenich’s case is revised and renewed with a
  gesture of understanding and reconciliation, Pope VI receives him in a private audience and offers
  him a chalice.

  When he was 83 years old, the venerable father Josef Kentenich dies on September 15, 1968
  on the day of Our Lord and the festivities of Our Lady of Sorrows right after he celebrated the
  Holy Mass. He was buried in the same sacristy and the epitaph(chosen by him) is a synthesis
  of his spirituality : “Dilexit Ecclesiam” ( “ I Love the Church” ). The life of this male saint of the
  church leaves us with a certain bitter sweet taste, his life was a total surrender , that with his
  convictions as a Man, first goes before an Image. I take this words and make them mine:
  !Venerable Pater Kentenich O.P.N.! « I am sad because my path never met with yours, but 
  I am happy because you have returned to the Father.»

   Father Angel Strada, 
    Postulator Of the 
    process of beatification.
 

  When it comes to the Image emblem of the Schöenstatt movement, in 1935 the venerable
  Kentenich explains clearly its meaning to Schöenstatt: It is true that just like the simple
  town embraces her with joy, for some of our most learned people it is sometimes a
  “stumbling block and scandal” and so causing a sentiment of rejection , causing a crisis
  in the relations to the Movement. The image arrived at the chapel in 1915 in a certain way
  by providence, to save us from a problem. Since the Movement has grown with Her, we
  cannot be separated any more.” He continues to say: “ It is very much possible that if our
  image had been made to please the modern taste, the Movement would have succumbed
  very quickly to the dangers of certain types of naturalism  and of  religious estheticism or
  of intellectualism, which would drive her to hear its “ death sentence” . But in this way,
  each learned person who is interested , feels the demand to make a personal decision to
  take a deeper look to the powers that work within him, and in this manner to affirm or to
  reject the Movement as a movement of life and graces. In this Image the “Scandal of the
  Cross” its permanently symbolized and expressed , which renders effective the great law
  of the Kingdom of God: “ He exalted the lowly”

 
  The Original was painted in Oil in this last decade of the XIX century by Swiss painter Luigi
  Crosio, born in Alba in 1835, died in 1915 in Turin, under the title of : “Refugium Peccatorum”
  ( Refuge of Sinners). The Dogma on the Immaculate Conception was not defined until
  December 8th 1844 by Pope Pious IX, with the Papal Bull Ineffabilis Deus.
  It is said that it is most probable that his daughter Ana posed as a model. Currently the
  painting is under the custody of the Sisters of Mary. Speaking in modern terms, the Image held
  record sales. On October 10th 1898 , the printing shop of the brothers Zurich Kunzli bought the
  rights to the Image and commercialized it in different versions, including also the lithography
  print in color. After 1914 when the students were being formed for the missions, they looked
  together with their spiritual director , for an image of Mary for the old chapel of St. Micheal, a
  professor from the institution bought one of these lithographic prints in an antique shop in 1915
  and gave it as a gift to the young Marian Congregation.
  Soon in Schöenstatt, the Image received the title: “ Mater ter Admirabilis”, Mother Thrice
  Admirable. The Blessed Virgin was venerated under this title in the XVI century at Ingolstadt
  where the Jesuit Priest Jacob Rem had founded the first Marian Congregation at the University
  of Bavaria.

  As an analyst, I see how father kentenich first of all organized the apostolic Movement
  and later divine providence provides the standards. In this case in a casual manner, with
  the Image of Our Lady ( “Refuge of Sinners” ) and the title of Mater Ter Admirabilis from
  Jocob Rem. 
  In the case of Our Virgin Mary Untier of Knots, it was only an image that during a period
  of 300 years was hidden from its true origin until my investigations, producing an
  explosion of faith in God’s country, from Argentina and throughout the world. From now
  on the only thing left to do for the devotees of the Virgin Mary Untier of Knots is to make
  the movement and its organization. 
  Rephrasing some of the principles of our brothers of the Schöenstatt Movement, we can
  say that: «The essential thing is our covenant of love with Mary in her Shrine. From
  there Mary, The Mother and Queen Thrice admirable has established her teacher’s
  “workshop” There she receives and transforms all her children and sends them out to
  the world like the apostles.»

  Note: Father Angel Strada is the Postulator of the process of beatification of P. Josef
  Kentenich. In respect to Jakob Rem, the diocese process of canonization ended
  in 1949. Due to “recent studies” beatifications and canonizations are now known and
  understood. Rome has the last word.
