Catholic Soteriology versus Semi-Calvinism
I refute Jimmy Akin’s doctrinal errors on predestination, grace, salvation. How serious are these errors? In my opinion, these errors are material heresy, since they contradict fundamental definitive teachings of the Magisterium on important matters of faith and salvation.
Akin is a former Calvinist, who converted to Catholicism. But his views on salvation, grace, freewill, and predestination have retained substantial errors found in Calvinism. Although Akin tries to reconcile the Calvinist view with Catholic teaching, the result is semi-Calvinism and serious doctrinal error, not sound Catholic soteriology.
