Calvinism is more than a mental assent to the Doctrines of Grace, much like salvation is more than a mental assent to the trinity and the Virgin birth or believing that the sinners prayer saves anyone
That being my position I feel the necessity of those that hold the doctrines of grace to defend them, even if the "offender" has a mental assent to the Doctrines of Grace and calls himself a Calvinist
Personally when I see Reformed posters nit picked, misquoted, mocked and corrected or rebuked for expounding the Doctrines of grace and/or the reformation, or when I see one that states he is a Calvinist seeking to find truth in the very basics that Luther, Calvin and others found in serious error, I find no need to wear a false fellowship mask for public consumption based on ones "self proclaimed" doctrinal position or church membership .
So, it may trouble you to find friends that all "say" they are Calvinists having public disagreements on the very basics the Reformation sought to correct, be of good cheer as the doctrines are being correctly presented through the lens of the Reformation and any presentation that is through the Catholic church and their doctrine is dutifully corrected and rebuked .
For some reason, I simply couldn't sort this post out.
If you wouldn't mind rephrasing it, I would appreciate it. Obviously, there's no necessity to do so. X.
