The way forward is for married people to live their married life very well, as if they were to be canonized saints.
A family life so demanding and happy and generous and open to life, setting an example of self-sacrifice and cheerfulness that every child would be imbued with, and they then see that married life is a great and irreplaceable good, that demands everything and yet gives every good thing, making them canonizable saints.
That’s the way…50 years of enormously well lived family life.
Then there would be fewer divorces, fewer broken homes, more 'dad’s in the life of children, more sacrfice, more example, fewer “stinginess” (less contracepting, fewer abortions).
And then maybe in 50 years the “bonus odor Christi” (the fragrance of Christ). would become so stong and attractive there would be fewer people off the trail pursuing deviant sexual expression…
