What they are trying to say with all the quotes and definitions is, basically, we are supposed to let God decide.
Unless we have a good reason to not have kids, we are supposed to have as many as God gives us.
“Not wanting any more” is not a good reason, according to Catholic teaching.
“Not being able to afford any more” is subjective, as many very poor people have lots of kids and still get by. God will provide. If they can afford them, so can most of us!
This is a hard teaching for many people, and one I’m still wrestling with myself, even though I’m not married yet. This is especially true in our culture today, where most people assume to “choose” our own lifestyle rather than trusting God with the majority of it.
Basically, saying “I’m just going to have 2 kids, cuz that’s what I want,” is selfish and not being open to the gift of life that God may want to bestow upon us more fully.
That’s how I understand it anyways.
