Codex Ephraemi Rescriptus (Paris, National Library of France, Greek 9; Gregory-Aland no. C or 04, von Soden δ 3) is a fifth-century Greek manuscript of the Bible, sometimes referred to as one of the four great uncials (see Codices Sinaiticus, Alexandrinus and Vaticanus). The manuscript is not intact: in its current condition, Codex C contains material from every New Testament book except 2 Thessalonians and 2 John; however, only six books of the Greek Old Testament are represented. It is not known whether 2 Thessalonians and 2 John were excluded on purpose, or whether no fragment of either epistle happened to survive.
