You may have heard it said that it seems reasonable to some that God would pass some of His divine nature on to Jesus in the "Immaculate Conception". Well no. It also makes sense if God would NOT pass on anything like that to the Christ just so that Jesus would be like us, a normal human to whom we can relate who can intercede for us. I can sit with a colleague in an exam room doing an exam and feel comforted that here beside me is someone in the same boat as me, with same brain and same potential, and after the exam we can go for a coffee and commiserate or rejoice on how our results might turn out. But that won’t be real if he had the answers preprogrammed into him from birth, or he was a superhero. Why would the Father spoil it all by imparting something to Jesus that we don’t have, that would make him different, and make his advice irrelevant and disqualify him as a true colleague. God did it perfectly, in love for us, giving us a true human like us as our truly overcoming lord, or truly relevant teacher and our truly sympathetic mediator with God. Denial of this is denying the Christ has truly come in the flesh.
