Recently I was looking up the Kurdish for ‘Son of Man’, because some Kurds have traditionally venerated one they call the Son of Man, and I found they use a word for Son (in Son of Man) which is almost the same as the Greek word used in the NT for Lord. Kurê Mirov is Kurdish for Son of Man. Kurê Is almost the same as Koine Greek for Lord - Kurios. Coincidence? Probably not. I suspect in ancient times the word later used for Lord in speaking of Jesus (in NT scriptures and among Greek speaking Christians) might had a close association with meaning of Son. This might shed light on why the Father is called the God in the NT while the Son is called the Lord.
