Our Lady of Fatima said that a girl named Amelia would stay in Purgatory until the end of the world. This is a sobering thought. If we pray for Amelia, her time in Purgatory might be shortened.
Remember that Sister Lucia said that missing one Sunday Mass (deliberately) can send one to hell for all eternity. The same applies for missing a Mass deliberately on a Holy Day of Obligation.
In view of this, it is good to remember St Therese’s teaching on avoiding Purgatory and going straight to heaven. The teachings are summarized here: http://www.franciscan-sfo.org/ap/litfwrpu.htm
