Well yes and know.Then of course comes the application or the practice which may show real variance. I think Paul and James are reconciled viewpoints.
There is a big difference in works because you are saved and works to be saved.
Beyond the semantic problem is the is the idea that sacraments are effective, in particular baptism. So you have a lot of P’s who believe, made a profession, been baptized, and think they are ok (saved) right there, and may not really be born again. You have Catholics also who have been baptized but are taught to do things (sacraments, Mass, good corporal works of mercy etc.) within the Church to be ok (saved). They may also not be born again but as long as they are striving to be a good Catholic they think themselves to be OK (saved/being saved).
So yes, I do not like faith alone if one thinks a profession of faith, yes to an altar call, and you are born again when maybe you are not . I also do not like your sacraments and Catholic religious life making one think you are born again when maybe you are not.
So I agree that profession of faith alone, or doing all the right “things”/works may or may not indicate a "saved’ soul.
