It's un Christian to think Christ did not exist before our concept of time and since He Did exist before the fall, Adam and Even and Moses, His Sacrifice is eternal being the 2nd person in the Holy Trinity.
Mark Bsnr expressed this perfectly in post 999 when he wrote...
Also, that Sacrifice covers all of Time. God exists out of Time and is eternal. We are not and we are subject to the laws of the created universe, being creatures of Him. That Sacrifice is as good for us now as it was for the folks at the beginning of Creation and all through Time to the end of All.
They do not understand the very issue of Time versus Eternity any more than they understand that Scripture was not written by King James in 1611 and emailed to Jesus and the Apostles for them to teach from. Apparently the Catholic Church ruthlessly ruled the Interwebs, confiscating all sites and email traces which contained the AV1611 except those carried on flash drives and disseminated person to person.
Meant to ping you to the post. Sorry
