One is not saved unless they accept Christ as their savior. That is a central basic component of christianity and commonly believed by Catholics and Protestants.
I agree, but for some here any belief not in keeping with what their denomination teaches is not believing in Christ.
How they accept Christ, through a church, through their own contemplation and understanding of Christ, with or without public proclamation to others is what is being questioned here. Questioned to the point where some are saying that Catholics or some other denomination that is not their own don’t believe in Christ or are never going to be saved because they don’t follow their dogma. God determines who is saved or not and you won’t know his decision until you face him.
Deriding the belief in Christ of other denominations because they follow a different path to salvation is ignorant and arrogant and certainly not in keeping with the teachings of Christ.
