The OP is very interesting. For those who don't believe that Sister Lucy 2 is the same as Sister Lucy 1, the message from Lucy 2 would probably be lacking elements if not an outright lie, or even be an attempt by anti-Fatima bishops to obfuscate about the real battle. The battle against marriage and the family has been going on for decades and while gravely sinister, there is something worse. Homosexuality. What does the breakdown of marriage and the family lead to? Homosexuality. The biggest battle until very recently admittedly has been about the breakdown of marriage and the family. But what has been going on in the clerical ranks is way worse.
The text by Sister Lucy 1 leads us to this conclusion as well: “Father, the devil is in the mood for engaging in a decisive battle against the Blessed Virgin. And the devil knows what it is that most offends God, and which in a short space of time will gain for him the greatest number of souls. Thus, the devil does everything to overcome souls consecrated to God because in this way, the devil will succeed in leaving the souls of the faithful abandoned by their leaders, thereby the more easily will he seize them. Religious and priests who fall away from their beautiful vocation drag numerous souls to hell..."
The text talks about "souls consecrated to God" That is not marriage and the family per se, it's priests and bishops. Also, the text mentions what most offends God and that has to be homosexuality, rape, the perversion of children and covering it up.
And now the pedo/homo crisis has come, being the consequence of marriage and the family, but far worse in what most offends God.
Excellent observation, Carissima
