Protestantism teaches that eternal salvation is a gift that is given to a person by God’s grace. It is sometimes called “unmerited favor.” This would mean that Salvation is God bringing humans into a right relationship with God through faith in Jesus Christ. It is the belief that one can be saved (rescued) from sin and forever death. Many Protestants believe in the “assurance of salvation”—that God can put confidence in a believer that he has truly received salvation from Jesus Christ.
Catholicism teaches that although in most cases someone must be baptized a Catholic to be saved, it is sometimes possible for people to be saved who have not fully joined the Catholic Church. Catholics normally believe in the importance of “faith working through love” and sacraments in receiving salvation. The Catholic Church teaches that good works and piety, such as obedience to commands, taking the sacraments, going to church, doing penance giving alms, saying prayers, and other things, are important in becoming holy, but strongly emphasize that salvation is through God’s grace alone, and all we can do is receive it.
Different denominations and traditions of Christianity believe in forms divine grace. Roman Catholicism and Eastern Orthodoxy teach the complete importance of the free will to work together with grace.Reformed theology teaches the importance of grace by teaching that a person is completely incapable of self-redemption, but the grace of God overcomes even the unwilling heart.Arminianism believes in a synergistic view, while Lutheran and most other Protestant denominations teach justification by grace through faith alone.
