Christian Churches teach that salvation comes through faith in Jesus Christ and obedience to the apostolic command of baptism by immersion. They emphasize that baptism is essential to salvation ('for remission of sins,' following Acts 2:38), not merely symbolic or optional. This understanding integrates justifying faith with baptismal obedience as part of the conversion process.

Their soteriology is fundamentally Arminian, affirming human free will and conditional election. God's saving grace operates prevenient grace enabling response, but the individual must respond through faith and obedience to the gospel. Apostasy is possible if a believer deliberately rejects Christ, so eternal security is not affirmed. This differs from both Calvinist predestination and purely faith-alone Protestantism.

The Restoration heritage emphasizes the pattern of the apostolic church: faith, repentance, and baptism by immersion as the normal pathway to salvation, with regular weekly communion affirming ongoing participation in Christ's covenant.
