Biblical Unitarians affirm that salvation is received through faith in Jesus Christ — his death, burial, and resurrection — and through repentance toward God. The atoning work of Christ on the cross is the ground of human forgiveness, and personal faith in that work is the means by which individuals enter into a saving relationship with God. Biblical Unitarians are committed Christians who hold the gospel of Christ's death and resurrection as central to their faith.

Baptism is widely practiced among Biblical Unitarians as an act of obedience associated with conversion, though the specific sacramental theology varies. Most Biblical Unitarian communities practice believer's baptism by immersion, following what they regard as the New Testament pattern. Salvation is understood as encompassing both forgiveness of sins in the present and participation in the coming kingdom of God — a future, earthly kingdom that many Biblical Unitarians understand in fulfillment of the Abrahamic and Davidic covenants.

Biblical Unitarians reject both the Calvinist doctrine of unconditional election (they hold an Arminian or conditionalist view of free will and human response) and the Catholic sacramental system of salvation through the church's rituals. Their soteriology is broadly evangelical in its emphasis on personal faith in the historical gospel events, while being non-Trinitarian in its understanding of the God to whom this faith is directed.
