Jesus Christ, the Word of God, is also called the lamb that was slain [from] the foundation of the world, which we take to mean the lamb that was slain [at] the foundation of the world.
Slain From the Foundation of the World
Foundation: καταβολῆς – katabolé
The "foundation-plan" typically relates to Christ's incarnation, i.e. coming to earth in the flesh to be our Redeemer. This divine plan was set and sealed (guaranteed) before creation.
Back to the Beginning
Some people believe that Genesis 1:1 is a subheading which bookmarks the beginning of creation, not as a creative act. However, some people believe that it was a separate creative act.
Stoicheia tou Kosmou
The periodic table of elements is an example of stoichiometry. Considering the use of the word stoicheia in Colossians 2:8, we can do some simple deduction based on Genesis 1:2 and resolve the Holy Trinity as a chemical formula.
Conception: καταβολῆς – katabole
The foundation of the world was an act of conception. Wisdom (Hydrogen, H+) fused with the Holy Spirit (alpha Oxygen, αO2-) to form the Hydroxyl ion (OH-). This existed with Wisdom (H+) to be the deep (H2O).
January 3rd
A laying down. The act of conception. The foundation-plan upon which the entire super-structure is built; the beginning (founding) that purposefully designs all that follows, that typically relates to Christ’s incarnation.
Propitiation
Propitiation is the price paid for our redemption. This was Jesus himself. He lived a sinless life and his sacrifice was sufficient to pay for the sins of the whole world.
