Writing on the British Jesuits’ site Thinking Faith, Hedwig Lewis, SJ, gives more background on the devotion to Mary the Untier (or Undoer) of Knots, which Pope Francis has promoted for years. You can also visit a website about the devotion. The devotion is especially appropriate for “problems and struggles we face for which we do not see any solution:”
Knots of discord in our family, lack of understanding between parents and children, disrespect, violence, the knots of deep hurts between husband and wife, the absence of peace and joy at home. They are also the knots of anguish and despair of separated couples, the dissolution of the family, the knots of a drug addict son or daughter, sick or separated from home or God, knots of alcoholism, the practice of abortion, depression, unemployment, fear, solitude. . .
