The Blessed Virgin Mary is dear to God the Father. Christ, Son of God and of Mary, loves His Mother and wants her to be loved and honoured. It is tragic, in His sight, that some Christians refuse to honour her. They discover, in Purgatory, the truth about their neglect of her, and they bewail the blindness of their earthly lives.
In the Father's sight, it is tragic that many Christians refuse to honour the Virgin Mother of their Saviour. How can they imagine that the perfect son of a perfect mother does not love her, does not honour her, and does not want all His friends to honour her, too? These Christians find out the truth when they die, and lament their previous blindness.
