"...The concept of Mary untying knots is derived from a work by St. Irenaeus of Lyons, "Adversus haereses" ("Against Heresies"). In Book III, Chapter 22, he presents a parallel between Eve and Mary, describing how 'the knot of Eve's disobedience was loosed by the obedience of Mary. For what the virgin Eve had bound fast through unbelief, this did the virgin Mary set free through faith.'..."
July 28 is the feast day of St. Irenaeus.
