Would you say anything to someone who refuses to be called a Calvinist under any situation; but agrees whole heartedly with the doctrines of grace?
They go about saying when we affirm the nick-name Calvinism/Calvinist like it or not we are going against Scripture. No theology or doctrine should be named after any man; regardless of the reason.
As far as they are concerning it is wrong to consider oneself a Calvinist.
They make a big deal about it, as well.
