Don’t ever stop praying for her. Pray for the intercessions of Saint Maximilian Mary Kolbe, who died by lethal injection and Saint Mark Ji Tianxiang, who was an opium addict.
I recently met a very holy priest who spoke with me about the intricacies of marriage and salvation. He said that when God unites two together in marriage, they literally become one flesh (Gen 2:24; Mark 10:7-8). In terms of salvation, that means that usually if one spouse goes to hell, then the other follows. Likewise, if one spouse goes to heaven then the other spouse follows. He said that God does not want to abandon families and will use any act of faith to save ones’ spouse, even a proclaimed non-believer.
He used an account of St. John Vianney as an example. There was a French woman, a faithful Catholic whose husband was an atheist. He spoke openly against the Church. At one point he became depressed and committed suicide by jumping off a bridge. His wife was beyond consolation and considered her husband lost. She traveled to the parish where St. John Vianney resided and was dismayed when she found a line for days to approach him in the confessional. She resorted to kneeling in the church to pray. Suddenly, St. John Vianney came out of the confessional and approached her. He exclaimed, “He’s saved!” She wondered how could that be, St. John Vianney explained, “I tell you he is saved. But he is in purgatory and you must pray for him. Between the parapet of the bridge and the water he had the time to make an act of contrition.” St. John Vianney further explained that God will use any act of faith towards one’s salvation – the fact that her husband didn’t object to a shrine she had in their bedroom and sometimes joined her in prayer, merited him final repentance and pardon in his final moments, a grace that Our Lady had obtained for him.
So GREAT is the mercy of God!
