I liked the link to the Artificial vs. Natural article - although I disagree with the notion that artificialness has nothing to do with it.
My understanding is that some of the Church’s justification is that we can’t separate the unitive and the procreative aspects of sex. To make this argument we need #1 to demonstrate that sex is naturally ordered to be both unitive and procreative. Any artificial
separation of those aspects changes the nature of the act.
But the real key to all this is:
Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred, Human life is sacred.
Sweetners are not sacred. Animal life is not sacred. Therefore we can use artificial sweetners. We can neuter our dogs.
When we hold something sacred, we don’t change it, or we are carefull not to entirely change the character of it. That’s what that means when we say “Sacred Tradition”, we (or the Holy Spirit) will never allow it to evolve so much that it is unrecognizable from the original. That’s why Bible translations must be done with the utmost care.
Also when we regard something as sacred, the instruments associated with it are set aside.
Special china is only used for special meals. It is the very act of reserving the china for special meals that helps set those meals apart. If that same china is then used for ordinary meals, it no longer has the power to make the special meals visibly special.
Likewise, if that act, which initiates a sacred human life is also used as mere recreation. The act loses it’s power to make visible just how beautiful, precious, and sacred human life is.
One of the “fruits” of contraception is jokes about how miserable parenting is. Jokes like: People arguing over when life begins: At conception? At birth? No, after the kids leave the house. Rather than children being the fruit of a very special and sacred act, children are now viewed as a burden that results from a “failure” of ABC.
