One may be a Calvinist and think of one's self as elect, but the reality may be different.
Since “elect” is synonymous with “saved” (justified), is ”Calvinist” any different than “Catholic” in that respect. In other words, is the following statement also true:
“One may be a Catholic and think of one's self as saved, but the reality may be different.”
That being so, how is Calvinism's concept of Limited Atonement useful?
I can only give my opinion on the subject of Atonement, which others can and do disagree with, but:
Neither “Limited” nor “Unlimited” Atonement is particularly useful for salvation at all. Our human opinions on who God should or did die for carries no weight on the GODHEAD. Therefore, Christ atoned for whom Christ atoned irrespective of my thoughts on the matter one way or another.
It is a theologically “philosophical” question (like ‘Could Jesus have sinned?’). If atonement is Universal, then (depending on what one thinks the atonement actually did) Jesus “wasted” his blood on many who will ultimately not be saved and God may punish the same sin twice (as I said, it depends on what one thinks the atonement accomplished). If atonement is “Particular” (the Baptist term for ‘Limited’) then Jesus blood was shed only for His sheep and effectively saved every person for whom it was shed.
However, these are human philosophical arguments that are not binding on God or His redemptive reality … so debates about “Atonement” are both extra-biblical and pointless.
No one knows for sure, without any doubt, that they are themselves elect.
Respectfully, I disagree. “Elect” is a synonym for “saved”. Do Catholics really believe that a person cannot know if they are “born again”? Redeemed? A child of God? Saved?
I cannot speak for others, but from my experience, the transformation was so self-evident that one cannot be “saved/elect/born again/a new creation” and NOT KNOW IT for sure.
