I'd hardly call him a "sacrificial son". I mean, they 3 of them co-existed from before the universe, and he didn't sacrifice him as you put it, he chose to let he's son come to earth, and be sacrificed for the sins of human kind.
Revelation 13:8 (NIV):
All inhabitants of the earth will worship the beast—all whose names have not been written in the Lamb’s book of life, the Lamb who was slain from the creation of the world.
If this translation is accurate, it implies that the sacrificial Lamb (presumably Jesus) was in some sense sacrificed prior to creation. This seems to be a
popular view among Evangelical Christians. In which case, my reference to Jesus as a "sacrificial son," is accurate, since the sacrifice is an eternal part of his nature and/or mission.
Different translations give different results though:
All who dwell on the earth will worship him, everyone whose name has not been [a]written from the foundation of the world in the book of life of the Lamb who has been slain. (New American Standard Bible)
and all the inhabitants of the earth will worship it, everyone whose name has not been written from the foundation of the world in the book of life of the Lamb that was slaughtered. (New Revised Standard Version)
These attach the clause "from the foundation of the world" to the
book, rather than to the Lamb.
And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. (King James Version)
Well, if Elizabethan English was good enough for Jesus, it's good enough for me! Slain from the foundation of the world it is! But wait, there's more:
And bow before it shall all who are dwelling upon the land, whose names have not been written in the scroll of the life of the Lamb slain from the foundation of the world (Young's Literal Translation)
This one could arguably be interpreted either way, depending on whether you think it means "written in the scroll [of the life of the Lamb slain] from the foundation of the world" or "written in the scroll of the life of the Lamb, slain from the foundation of the world."
This sort of thing ought to set off alarm warnings in the mind of every "Bible-believing" Christian. Whether it's
Jesus that was slain from the foundation of the world (making his sacrifice an eternal aspect of his nature, hence "sacrificial son"), or the
names of the saved being written in the book before the foundation of the world (and thus, no free will)...is kinda
important. The whole premise of a perfect, infallible, all-powerful god who wants to communicate his self-revelation to* us through a book--and that our eternal destiny should depend on our specific understanding of it (i.e., Vile Heretics burn in Hell)--collapses when you run into something like this. Fortunately, this thread happens to be in the right section of the Forum.
