Kevin, I do not understand why Joe cannot humbly go to Confession and live chaste with his second wife.Why does it have to be unrealistic? With God all things are possible. Without Him - then I agree with you - they cannot achieve a chaste lifestyle. When we rely on ourselves, rather than humbly go to God on our knees in prayer, by praying the Rosary (Our Blessed Mother who is without sin will turn our human prayers that may not always align with God's Will into prayers that will align with God's Will). Back on the Feast of the Sacred Heart (usually around June 6th or 7th each year) in 2015 after Mass I approached our organist (she was alone) who I had noticed never received Jesus in the Sacrament of the Holy Eucharist. I asked her why and she responded, "My husband died 5 years ago and for the last two years, I have been in a sexual relationship with a man who was married and until yet has not obtained an annulment. She felt she could not ask him to live chaste. TBC
