According to Douglas Moo, the UBS4 and NA27 Greek New Testatments cite "Junia" as a variant reading.13 This variant reading is attested to by Codexes Sinaiticus (a), A, B*,C, D*, F,G, P. The GNT also cites "Julia" as a variant reading. Support for this female name is evidenced by P46, 6, itar,b, vgmss, copbo, eth, and Church Father, Jerome.
According to many scholars, Junia was a common name that appeared in Greek and Latin inscriptions and literature. Brooten states, "the female Latin name Junia occurs over 250 times among inscriptions from ancient Rome alone."14 Peter Lampe has also discovered over 250 examples of the female name Junia.15 Bruce Metzer, editor of the GNT, likewise agrees that Junia is well attested to in ancient literature.
a. Discussion. Support for a female named Julia is evidenced by P46, a papyrus manuscript, dating from around a.d. 200. This papyrus represents the earliest known and most reliable testimony in support of Julia.
The 3rd century Coptic, 4th century Vulgate, and fifth century Latin versions provide additional early support for this female name. These early manuscripts clearly support a female named "Julia." Junia, the other variant reading, is supported by the earliest known manuscripts available. Sinaiticus dates from the fourth century and is earliest surviving complete copy of the Greek New Testament.16 Codexes A, B, C, D date from the 4th to 5th century and represent a broad spectrum of "text types." These early witnesses, by themselves, do not clearly reveal how an unaccented Iounian should be translated. The cumulative evidence provided by other ancient manuscripts, the existence of "Junia" as a common name in ancient times, and the lack of any evidence for "Junias" cannot be ignored. It is not unreasonable to state, as Moo does, that these early witnesses attest to "Junia."
b. Assessment. The quality and age of the above manuscripts provide strong support for a female name whether it be rendered "Julia" or "Junia." The research from many different scholars clearly support that a female named Junia occurred frequently in ancient writings.
