I tend to agree. Not only does such a view make the church virtually irrelevant, but also deprecates the sacrifice of He who died for her. Not to mention that such a view is founded in atrocious self-righteousness and bordering on full-on Pelagianism.
By the way, in reference to this statement: "Right now many scholars put it at about 40 percent who attend regularly are actually saved." I would like to see what "scholars" made that claim, and examine their research methods, the size of their sample, and how, exactly, they determined who was saved and who was lost.
Until then it is just mindless drivel.
