 Because the BC/AD notation is based on the traditional year of the conception or birth of Jesus, some Christians are offended by the removal of the reference to him in era notation.The Southern Baptist Convention supports retaining the BC/AD abbreviations.Roman Catholic priest and writer on interfaith issues Raimon Panikkar argued that the BCE/CE usage is the less inclusive option as, in his view, using the designation BCE/CE is a "return... to the most bigoted Christian colonialism" towards non-Christians, who do not necessarily consider the time period following the beginning of the calendar to be a "common era".
