Please use a modern translation, such as the NET with its footnotes.
1) The Second Person of the Trinity was known before creation to be the Lamb of God.
2) Christ was slain on the cross about 2000 years ago, not before creation.
3) The plan of Redemption included the death on the cross of the Lamb of God, thus before creation.
4) Christ was put to death according to the predetermined plan and foreknowledge of God.
Please do not engage in time travel theology based on mistaken translations of Greek grammar!!!
Does your line 3 above say, before creation God planed for Christ as of a lamb would, in the fulness of time be born of woman and would die? Before creation, Christ was going to die? Was this predicated upon an, if or was it going to take place?
Here is a thought, in a question.
We have it stated in the Heb 2 What is man section; But now we see not yet all things put under him. Under the following from 1 Cor 15:45,46 And so it is written, The first man Adam was made a living soul; the last Adam
was made a quickening spirit. Howbeit
that was not first which is spiritual, but that which is natural; and afterward that which is spiritual.
Why was man first made natural and then to be made spiritual at some point in time, afterward?
Did death have anything to do with how he was first made?
For it became him, for whom
are all things, and by whom
are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings. Heb 2:10
Why was man made a little lower than the angels? Relative to angles, what will the status of the future man? Luke 20:36 Neither can they die any more:
for they are equal unto the angels; and are the children of God, being the children of the resurrection.
Was the appointment of death also the plan before creation? After this the judgement.
