I wasn't referring to "calling". I was referring to the last word in 1Cor 1:26, "called" highlighted in blue as here:
The title of your OP is 'The Nature of "called" in 1Cor 1:26-31' where in v26 called is not in the Greek text. It was added to the English translation, but does not exist in the Greek text. The 4th word 'calling' is indeed in the Greek text, but the last word of v26, 'called', is not in the Greek text.
First, I never said that it was in the Greek text. That is your complete assumption. I simply quoted the English text. Second, it is placed in italics to show that it is not found in the Greek text. Why then include it? The translators included it because the sentence demanded its inclusion to make sense. It's omission is an ellipses but necessarily inferred and demanded by the sentence to provide the complete sense intended by Paul. Paul points to their "calling" and then states that "not many" of this classification or that category of mankind were included in that calling. His very argument demands the calling by God has LIMITATIONS. The obvious point Paul is making is that "not many" of this or that are "called. BUT God hath chosen." The very nature of Paul's argument demands the inclusion of "called" and the translators could see this clearly.
Not only so, but other modern translations see this is clearly an ellipses (ommission) that the very nature of the sentence requires to make its meaning clear:
NIV - Brothers and sisters, think of what you were when you were called. Not many of you were by human standards; not many were influential; not many were of noble birth. - 1 Cor. 1:26
ASV - For behold your calling, brethren, that not many wise after the flesh, not many mighty, not many noble, [are called]
WEY - For consider, brethren, God's call to you. Not many who are wise with merely human wisdom, not many of position and influence, not many of noble birth have been called.
The above are just a sampling of many other translations that see the obvious intent of Paul's statement as it is this "calling" that he is limiting ("not many") from various categories/classifications "according to the flesh" meaning the majority in these classifications were NOT CALLED and were NOT CHOSEN by God to show that such characteristics were not determinate in putting them "in Christ" but their placement "in Christ" was purely "OF GOD" and due to NOTHING that characterizes them.
The subject is their "calling" and the words "not many" show obvious LIMITATION in each classification/category listed. The prepositional phrase "according to the flesh" shows he is not comparing brethren with brethren but referring to their previous new birth status among classifications of lost persons. The phrase "BUT God hath chosen" defines who and how the limitations were determined.
Your view does not fit the context! Verses 29-31 define Paul's objective for what he says in verses 26-28. Your view makes no sense when the overall contextual subject is salvation and the objective of Paul is to remove any human claims before God for how they became "in Christ" and thus verses 26-28 are negatives or denials for claims to have obtained "in Christ" status due to anything found in them.
Therefore, I explained what the nature of 'called' is in 1Cor 1:26-31 - it has No Nature, there is no nature of 'called', as it doesn't exist in the Greek text of those verses.
Your explanation is false and bogus. These terms describe CLASSES of humans or CATEGORIES "according to the flesh." That is the natural interpretation and yours is completely forced upon the text.
But go ahead and attempt to build a case for Calvinism on these verses with a word that is not in the Greek text. You are only deterring your own cause, supporting my claims that you assume much, and that Calvinism must eisegete the Scriptures.
I just showed you the word "calling" is in the text and is the very same word identified with "election" by Peter (2 Pet. 1:10) as it is here by Paul. I have showed you that LIMITATION is demanded by the words "not many." I have showed you the determinate cause for those called out of those categories "acccording to the flesh" was due to election or God's choosing "But God hath chosen" not according to their choosing as Paul's climatic aim is to show NONE have anything to claim for being "in Christ" instead "But OF HIM are ye in Christ."
Anyone can do what you are doing, slice and parse parts of the text in order to avoid and ignore the obvious overall contextual flow and the very clearly stated goal of the text.
