If He's on the altar it goes against Scripture.
If He's on the altar it's happening....on the altar...again and again and again as a RC priest acknowledges.
The whole thing is against what is described in Hebrews.
This particular error is not something rampant in the Ancient Churches, all of which have, for nearly 2 millennia, believed in the heavenly Altar, the heavenly Priest, the Lamb "slain before the foundation of the world," and thus realize we must worship in Eternity, in unity with the Angels; and we do.
Of course you can't fathom it. Nobody can, this side of Eternity. That's a given.
Tagline.
Oh? If anything else is on the altar, it's blasphemy.
