*big heavy sigh*
There is no logical reason why anybody with a brain should be caught up in such nonsense, and it's a terrible reason to tamper with the natural course of pregnancy and childbirth.
Evangelical Christians on the board, please feel free to show me where I'm wrong in what I'm about to say. I'm actually not an evangelical Christian, but I was one recently enough and for long enough that I know the whole theology inside and out and can address most theological questions with confidence--even if I am damned to hell myself.
Okay, here goes. Here's the deal.
First off, it's only Christians for whom the number 666 means a thing, because it's in the Book of Revelation as the number that the Antichrist will bear. It's not made altogether clear just how the Antichrist will bear a number, but that's what it says, and it's in the Christian Bible, so there's no logical reason for non-Christians to be hung up on it. Now, as for Christians, they have even less to worry about. Why? Simple. The most basic article of faith in Christianity is that all anyone has to do, in order to be kept safe from all manner of spiritual harm, is hold fast to the faith. Christ made clear to his disciples that nobody could predict the time the world would come to an end, so therefore they should be ready for it at all times. Can any Christian seriously believe that that a faithful Christian would be in trouble with God just for having given birth on June 6, or for having been born on June 6?
Point is, non-Christians have no reason to think about the number 666 at all, and Christians have no reason to fear some silly numerological superstition when all they have to do is keep the faith. Therefore, it's utterly inane that anybody would be worrying about giving birth on June 6. And for God's sake, pregnant women have enough to think about without this nonsense.
Am I right or am I wrong? As Martin Luther* said, "show me where I'm wrong."
*I quote Martin Luther while also acknowledging that he very much deserved to be shown where he was wrong in his anti-Semitism. It's a great quotation nonetheless.
