That fruitfulness is ultimately relational, not merely transactional. That a child is fruit from a relationship, not the product of a mere transaction.
I'm afraid I don't understand what you're talking about. It's the men on this forum, for example, who are giving me the impression that they view kids as a product. And that they don't care what happens to this "product". They only care about multiplying it. I don't know, maybe it stems from lower empathy levels in men.
Read Karol Wojtyła's Love and Responsibility for an excellent exposition on the topic.
He wasn't married and had no kids. He didn't "multiply" lol So why should I listen to him on this topic? :)
And God said to them, "Be fruitful and multiply and fill the earth and subdue it (...)"
Well, and people did that - they filled the Earth and subdued it already. This made sense long ago when there weren't many people yet. But now? Do you want the planet to get overpopulated? Religious people should also use reason - that's one of God's gifts to us, isn't it.
The bottom line is our ultimate problem in the west is our understanding of human love has become completely turned inside-out and disordered
Sorry, but, again, I don't know what you're talking about.
