Justification (its source God and his grace, its ground Christ and his cross, and its means faith alone, altogether apart from works) is the heart of the gospel and unique to Christianity.  No other system, ideology or religion proclaims a free forgiveness and a new life to those who have done nothing to deserve it but a lot to deserve judgment instead.  On the contrary, all other systems teach some form of self-salvation through good works of religion, righteousness or philanthropy Christianity, by contrast, is not in its essence a religion at all; it is a gospel, the gospel, good news that God's grace has turned away his wrath, that God's Son has died our death and borne our judgment, that God has mercy on the undeserving, and that there is nothing left for us to do, or even contribute.  Faith's only function is to receive what grace offers.
