The Visitation prolongs the Annunciation. Our Lady acts as heavenly midwife to St John the Baptist, the Precursor of the Sovereign High Priest. She forwards to him the Holy Ghost to graft him into the mystical Body of her Son, while carrying Jesus as the Head of the same Body. The devotion to ‘Mary Undoer of Knots’ illustrates this truth. All further members must be connected to their Head through Mary. Despising her spiritual motherhood binds one to the Father of Lies instead, as no middle path is offered.
