User blog comment:Thetwindler/Is Castiel Still a Seraph?/@comment-70.93.83.195-20181102232925

A Seraph is a higher rank/type of angel, so that is why Cass still calls himself an angel. You make a valid point though as it indeed been long time since he was referred to as a Seraph. But to assume he is no longer one due to that fact is speculation because as far as we know Cass is still a Seraph as nothing has been said to the contrary since Season 8, therefore is no proof either that he isn't a Seraph anymore.
