What Does the Name Theodosius Mean?
Theodosius is the Latin form of the Greek name Theodosios (Θεοδόσιος), meaning "God-given" or "given by God." The Greek name combines theos (θεός), "god," with dosis (δόσις), "a giving" or "gift," from the verb didōmi (δίδωμι), "to give." The usual English rendering, "God-given," treats the compound as describing a person given by God; the Greek elements themselves are closer to "god" plus "giving."
Theodosius Name History & Origins
The name is Greek in origin and was used in the Greek-speaking world before it became prominent in Rome. An early bearer was Theodosius of Bithynia, a Greek astronomer of the second century BC. The name entered Latin as Theodosius and was borne by several figures in the later Roman Empire. The most famous is Flavius Theodosius (347 - 395), emperor from 379, who made Nicene Christianity the official religion of the empire and whose death in 395 divided the empire between his sons Arcadius and Honorius. His grandson Theodosius II (401 - 450) ruled the Eastern Empire and ordered the compilation known as the Theodosian Code.
The name continued in use in the Greek-speaking Christian East, where several saints bore it, including Theodosius the Cenobiarch (c. 423 - 529), a monastic founder in Palestine. It also continued in Byzantine imperial use: Theodosius III was emperor from 715 to 717. The Latin form Theodosius is the source of the English name; related modern forms include Italian and Spanish Teodosio and French Théodose.
