[Topic] Salvation [Orthodox] Salvation is "faith working through love" and should be seen as a life long process. The Ultimate aim of every Orthodox Christian is to obtain Theosis or union with God. This is done through living a holy life and seeking to draw closer to God. [Roman Catholic] Salvation is by grace, specifically sanctifying grace, which is given initially through Baptismal regeneration and then maintained through the Sacraments, which are 'channels of grace'. [Protestant] 
Salvation is the free and unmerited gift of God to man. It is obtained by grace through faith in Christ alone. Through Christ's atoning sacrifice, we are rendered acceptable to God and judged righteous (justified) in his sight.
