I’m curious what other people might think, or what kind of theological work has been done in this area. This seems like a pretty straight forward type of question that you might get in a Sunday school class (kids or adult). Things like, “did Jesus ever make a mistake?” and “did Jesus know who he was as a child”, etc.
To @Robert_Byers’s point, Luke 2:52 (NRSV) says:
And Jesus increased in wisdom and in years, and in divine and human favor.
The same verse in the NIV says:
And Jesus grew in wisdom and stature, and in favor with God and man.
It seems that Jesus grew both biologically (years/stature) and mentally (wisdom). I wonder how that happened exactly as we think about minds and brains? If we think about the hypostatic union (Jesus is both full human and fully divine in one existence), what do we do with the brain and the mind? Was his brain human and his mind divine?
Another area would be kenosis (self-emptying) of Jesus. Here, is Philippians 2:6-7 (NRSV)
who, though he was in the form of God, did not regard equality with God as something to be exploited, but emptied himself, taking the form of a slave, being born in human likeness. And being found in human form,
And again in the NIV:
Who, being in very nature God, did not consider equality with God something to be used to his own advantage; rather, he made himself nothing by taking the very nature of a servant, being made in human likeness.
So, is that what @Robert_Byers is saying with “When born he was stuck to a human memory/mind. so he couldn’t remember all the God stuff he knew.” I’m nervous about “memory” there. Does that mean a pre-existing memory or just an empty memory?
P.S. I’m not sure if “neuroscience” is the right phrase here. I’m interested in that too, but for now it seems a bit more like psychology of the Incarnation I guess.
