Labeling does often bring a certain amount of misconceptions, even unwanted luggage that clutters the threads.
There is a problem with the label "Calvinist" or "non-calvinist" is because not all hold to the exact same thinking of the various items.
For example, when it comes to what constitutes the limit to atonement there is a range of acceptance (toleration) that many outside the camp of "Calvinists" don't recognize when one is branded with a label.
"Reformed" has the connotation of emerging from some institution that needed realignment. For the most part, Baptist folks don't consider themselves ever having been aligned with the RCC, or even some protestant grouping.
Application of labels has always been a problem for the Baptists, though they do like to use them against others, they do not easily accept a label that is not self applied.
On the BB, getting to know a person's views takes time. And though respect is willingly given to all "newbies" the matter of esteem is built over time. That someone has a history and a certain style is important. We wouldn't need two of the same types on the BB. Can you imagine two agedman?
There is one problem that I don't know this thread has yet to explore as it concerns "what others believe..."
That is when a poster points out and actually quotes from the writing of another poster, and yet the one quoted goes into denial.
How would be an effective way of responding?
ignoring?
confronting?
place the quote in bold?
Why is it hard for some to say, "Yes, that was a bad position in which I no longer hold, and am willing to openly admit was mistaken?"
Psychologically, such is just not allowable in certain personality types.
It presents a certain weakness.
It presents an opening for shame.
I presents a vulnerability for humiliation.
(and so forth)
What the BB should represent is that such admission can and does take place in the fellowship of support and understanding pouring from the truly educated. That rejoicing breaks forth in abundance of support.
