What is a "denomination" ?<quoted text>
"Christianity" is made up of 38,000 different "groups" most of whom do not consider the others Christians.
The Only "Christian Denominations" that have existed since 400 AD are the Roman Catholic and Eastern Orthodox Churches. All the rest are heretical and NOT "real Christians".
Of course even the Roman and Orthodox Churches are not even closely related to the Jewish cult begun by Jesus and a few other Jews in the first cent. AD.
