Classical logic holds that the negation of a universal affirmative immediately implies the affirmation of a particular negative.
If “not all will go to the game,” then “some will not go to the game.”
Now, Jesus says, “Not everyone who says to me, ‘Lord Lord,’ shall enter the kingdom of heaven” (Mt 7:21). Jesus is negating the universal affirmative. Thus, he is immediately implying the affirmation of the particular negative.
Thus, a logically equivalent expression is: “Some are not saved.”
And Jesus is speaking of men.
For classical logicians, we gather from knowledge outside the statements that “humans exist.” The statement, that is, is simply about existing human beings. Thus, the ultimate yield is: “There are some men who are such that they will not be saved.”
Symbolic logicians contend that the affirmation of a particular (negative or affirmative) constitutes an existential claim.
So, it seems on the count of either logic, that Jesus affirms that some men are damned.
