The handwriting has many similarities with P. Egerton 4 (2 Chronicles) of the third century, and even more so with P27, which may be the work of the same scribe.
Contents: P46 contains most of the Pauline epistles, though with some folios missing. It contains (in order) “the last eight chapters of Romans; all of Hebrews; virtually all of 1–2 Corinthians; all of Ephesians, Galatians, Philippians, Colossians; and two chapters of 1 Thessalonians. All of the leaves have lost some lines at the bottom through deterioration.”
Papyrus 3 is designated by the sign P3 in the numbering Gregory-Aland. It is a small fragment of fifteen verses from the Gospel of Luke (Luke 7:36-45; 10:38-42) dating to the 4th century.
P66 Papyrus 66 [150 C.E.] is of the Alexandrian text-type (more trusted). P66 comes to us by way of a professional scribe (practiced calligraphic hand, pagination numbers), a major corrector and a minor corrector.
