Common Era The expression has been traced back to 1615, when it first appeared in a book by Johannes Kepler as the Latin usage vulgaris aerae,[5][6] and to 1635 in English as "Vulgar Era".[b] The term "Common Era" can be found in English as early as 1708,[7] and became more widely used in the mid-19th century by Jewish academics. In the later 20th century, the use of CE and BCE was popularized in academic and scientific publications, and more generally by authors and publishers wishing to emphasize secularism or sensitivity to non-Christians, by not explicitly referencing Jesus as "Christ" and Dominus ("Lord") through use of the abbreviation[c] "AD".[9][10]
Dating the Bible This table summarises the chronology of the main tables and serves as a guide to the historical periods mentioned. Much of the Hebrew Bible or the Protocanonical Old Testament may have been assembled in the 5th century BCE.[1] The New Testament books were composed largely in the second half of the 1st century CE.[2] The Deuterocanonical books fall largely in between.
