Saint Nicholas was born about 275 AD in Myra; he eventually became Bishop the Christian Church in the Asia Minor city of Myra (now Demre, Turkey) in the fourth century AD.
He is beloved throughout the Christian East for his kindness and help, both during his life and afterward. He is called "Wonderworker" (or "Miraculous" or "Miracle-Worker", different translations of the Greek "θαυματουργός") for the numerous miracles which he performed and which he still performs, by God's grace.
In the Protestant West, which suppressed the invocation of saints, Saint Nicholas became popularly known as Santa Claus.
Honor and Glory to God in the Highest.
