I didn’t know what I was going to write about here, until this morning, when I saw this, or for a more concise bit on the exact thing that I'm thinking of, go here. Go ahead, click on of the links. You know you want to, and, frankly, the rest of this entry won’t make any sense if you don’t.
Okay, fine, I'll explain where I'm going to those who have a phobia of links. The links go to an article and a blog entry about the "quiverfull" movement (AKA the patriarchy movement - their own term, not one that they've been labeled with). This movement holds that it is the responsibility of a Christian woman to have as many children as she possibly can, regardless of the impacts to her health (and she is to have essentially no life outside of the home), and that it is the responsibility of a Christian man to get his wife pregnant as often as possible. The basic idea being that they will grow in population, outnumber the "infidels", and be able to enforce their will on the rest of the population. It's sort of like a very slow-moving version of a James Bond villain.
Lest you think that I am being overly alarmist, I will point out that I am not worried that these people will succeed, I feel relatively certain that they won't, and while their numbers are growing at the moment, movements like this have never really succeeded in the long-term and tend to burn themselves out. I also am not exaggerating their aims, they are very open about their plans for world domination (though they call it other things, like "taking the world for Christ" or "remaking the world in a Christian image", but lets call a spade a spade, and let's call plans for world domination plans for world domination, shall we).
Katherine Joyce has studied the quivefull movement, and written articles and a book on them. From one of her articles linked above comes the following quote:
Among yet more extreme believers, such as the pro-patriarchy homeschooling ministry Vision Forum, some movement leaders urge followers to develop a "200-year plan," to chart out generations of children, grandchildren and great-grandchildren for centuries to come, along with tasks they want those descendents to fulfill to glorify the family name. "If the Christian Church had not listened to the humanistic lies of the enemy and limited their families," writes Vision Forum founder Doug Phillips in an introduction to the movement book Be Fruitful and Multiply, "the army of God would be more powerful in this hour. The enemy's camp would be trembling."
It's absurd, on one hand, to believe that two hundred years' worth of heirs will follow an ancestor's goals so closely, but it's also a logical extension of the "demography is destiny" argument that Quiverfull relies upon: that through the sheer number of their offspring they will be able to enact their will upon the culture around them.
...and I can't think of a better example of sinful pride, or as it should more accurately be called, hubris, than this. Not only do these people suffer from the grandiose notion that they will reform the world in their image (it's too bad that they are pretty strongly anti-science, as they would make GREAT B-movie mad scientists with that attitude), but they expect that their decendants, long after they're gone, will continue on with their plan as they conceive it now.
Certainly, pushing for believers to reproduce beyond all sanity is not unique to this particular sect - it's a feature of many religions. However, this particular super-villianous twist is something truly odd. The fact that this particular "deadly sin" is so strongly displayed by a group so determined to make the world fit their definition of "holy" is an amazing irony.
