OK that is clear as mud so let me ask another question based on that same post. In your view can one deny the Calvinist view of "effectual call" and be born again?
The phrase "effectual call" is not an expression found in the scriptures. However, quickened/regeneration/born from above/born of God/eternal life/called are all Biblical expressions that are used interchangably as you can only find "called" in Romans 8:30 rather than its other synonyms of the new birth.
I would never infer or call anyone a heretic that refused to acknowledge that the word "called" is used as a synonym for regeneration. However, I would call a person a heretic that repudiated the new birth and that was the point of my post.
The reason I chose to define heresy and heretic in that particular post and apply it to those who repudiate the new birth prior to the cross was due to the fact that Winman, although not saying it clearly, was near to inferring the new birth was only a Post-cross reality. However, as you can plainly see I did not accuse him of embracing that idea but made it plain if that was his intent or inference then I would treat it as absolute heresy rather than a mere difference of opinion or interpretation.
There is sufficient room for difference of opinion on many things but not in regard to the essentials of the faith. Those essentials are made quite clear in the Scriptures because the scriptures use language that explicitly demand they are essential and the new birth is such a teaching.
There can be no salvation for any sinner at any time apart from regeneration. That is not to say there are not other essentials as well (justification, sanctification, glorification; etc.) but repudiation of the new birth is heresy.
