It's above the Pope's pay grade, as well:
"The Magisterium has not expressly committed itself to an affirmation of a philosophical nature [as to the time of ensoulment], but it constantly affirms the moral condemnation of any kind of procured abortion."
The Pope doesn't know when the soul enters the zygote. But McBush knows!
At what point during conception does the soul enter the egg? Tell me, McBush. When?! When the fertilized egg divides? When the cell implants on the wall of uterus? When the sperm enters the egg? What if the egg never implants and dies? Does it go to hell or purgatory -- because it wasn't baptized? Does McBush even know what a "zygote" is? Can he spell the word "blastocoel"? He didn't even know that Iraq doesn't border Pakistan. Heh? McBush? Heh?!
No, sir, this stuff is above McBush's "paygrade" as well. To know for certain the answers to these questions is being -- what's the word? -- presumptuous.
