Re: What's the difference between redemption and salvation?
Basically, redemption is collective and salvation is individual. By his passion, death, and resurrection, Christ redeemed humanity collectively from slavery to sin and from the debt of punishment mankind -- as a whole -- owed due to sin. Each and every person, Christian or non-Christian, is redeemed because he is a member of the human race.
Salvation is the application of redemption to individuals. Although a member of redeemed humanity, and therefore himself redeemed, a person can freely choose to deliberately reject the graces won for him by Christ and go to hell.
