BCE = BCE stands for "Before the common era." It is eventually expected to replace BC, which means "Before Christ." BC and BCE are also identical in value. Most theologians and religious historians believe that the approximate birth date of Yeshua of Nazareth (Jesus) was in the fall, sometime between 7 and 4 BCE, although we have seen estimates as late as 4 CE and as early as the second century BCE.
 
CE = CE stands for "Common Era." It is a relatively new term that is experiencing increased usage and is eventually expected to replace AD. The latter is an abbreviation for "Anno Domini" in Latin or "the year of the Lord" in English. The latter refers to the approximate birth year of Yeshua ben Nazareth (a.k.a. Jesus Christ). CE and AD have the same and value. 2004 CE = 2004 AD.


 


Size of Religious Organizations which have a recognized, central
leadership or convention, and a body of individual members or
adherents.

Note: As used in the chart below, "religious body" is a technical term used in the classification of religious groups. It is based on organization, not theology. Many important worldwide religious groupings have many adherents, but are not organized into a single organization classified as a "religious body" (e.g., Evangelicals, Lutherans, etc.).

* Catholic Church: Includes non-Latin Rites in communion with Rome, such as Ukrainian Catholics, Coptic Catholics, etc.

** Jehova's Witnesses: This 14+ million figure is the approximate number of adherents -- intended to reflect all those who consider Jehovah's Witnesses their preferred faith, regardless of current activity status. Figure is based on reported once-a-year memorial attendance (adjusted). Actual number of publishers was 6 million worldwide in 1999. Worldwide, the number of practicing Jehovah's Witnesses may actually be higher than the number of practicing Anglicans.

Note again: As used here, "religious body" is a technical term used in the classification of religious groups. It is based on organization, not theology. Many important worldwide religious groupings have many adherents, but are not organized into a single organization classified as a "religious body" (e.g., Evangelicals, Lutherans, etc.).
