I apologize for my poor wording. What I believe you have made clear is that “Mother of God” does not appear in Scripture and I agree with that. I’ll also take your word “God the Son” does not appear in Scripture.
But Scripture does make clear that Jesus is God, and I simply do not understand how you can separate Jesus from God.
Doing a word search on the phrase *God the Son* on any Bible website will come up with no results.

Please show where I separated Jesus from God.
Yet you would purport to tell us how Jesus being both fully man and fully God functions?
The Holy Spirit did not call Mary the "mother of God". Man giving her that title purporting to understand the nature of Christ is pure folly.
