You, like many "cals" like to misrepresent what others believe. You like to characterize differing views based on your disagreement rather than try to honestly represent them. Your source is wrong, I know of no one who is a non call who denies penal substitution. There are most likely some but to broad brush all in this manner is just not honest. Maybe you should resolve your cal/noncal obsession.
Just saying that historically, that some of the proponents of Arm /non cal theology regarding Sotierology have had to adjust off the Substitutionary model of the Atonment to one of the other theories held in Church history...
Think they were honest, and faced that IF they held to jesus substituting for all, as he is said to have died for sake of all...
That would force them to eventually have either sinners left in hell , with jesus paying for their sins, or else forced to adopt Universlaism...
There are/were held other theories regarding atonement in the church....
