Has anybody noticed that Protestants have disappeared in the past 50 years? Okay, not really but I mean people who claim to be "Protestant." When I was in high school, when people identified their religion they would almost always answer as Catholic or Jewish or Protestant. Nowadays you rarely hear Protestants use the term "Protestant." Instead they will either name their particular denomination or give the generic answer of "Christian." But as to claiming to be "Protestant"...you rarely hear that anymore.
I identify as a Christian.
Perhaps it is because "Protestant" began as a derogatory label for those who broke away from the Roman Catholic church after the Reformation. They were sneeringly called "Protesters". Even here on the Religion Forum there are still some who do that. Plus, many of the "mainline" Protestant denominations have devolved into mere shells of how they began and who no longer teach the major tenets of the Christian faith, preferring to water them down or neglect to defend them in the face of political correctness.
I was a Roman Catholic who converted to Southern Baptist but I now consider myself a Christian or an Evangelical Christian. I have worshipped in Southern Baptist churches, non-denominational churches and even a Lutheran church for a short time. What I care most about is what they teach not what their sign outside the door says.
