Salvation did not originate in Christianity. The Greek Hellenistic religions were the original salvation religions and they occupied Israel 1 century before Christianity started.
Also savior deities, redemption fro souls getting to an afterlife, baptism, eucharist and other Christian concepts were first in Hellenism.
The Britannica entry on Hellenistic religion really illuminates what came from the Greek traditions. The dates for this movement is 300 BCE to 100 CE, so they were the originators.

Changes that religions began taking from Hellenistic religions (this describes Judaism to Christianity exactly) - how many times is salvation mentioned.
-the seasonal drama was homologized to a
soteriology (salvation concept) concerning the destiny, fortune, and
salvation of the individual after death.
-his led to a change from concern for a religion of national prosperity to one for
individual salvation, from focus on a particular
ethnic group to
concern for every human. The prophet or saviour replaced the priest and king as the
chief religious figure.
-his process was carried further through the identification of the experiences of the
soul that was to be saved with the vicissitudes of a divine but fallen soul, which had to be redeemed by cultic activity and divine intervention. This view is illustrated in the concept of the paradoxical figure of the
saved saviour, salvator salvandus.
-Other deities, who had previously been associated with national destiny (
e.g., Zeus,
Yahweh, and Isis), were
raised to the status of transcendent, supreme
-The temples and cult institutions of the various Hellenistic religions were repositories of the knowledge and techniques necessary for
salvation and were the agents of the public worship of a particular deity. In addition, they served an important sociological role. In the new,
cosmopolitan ideology that followed Alexander’s conquests, the old nationalistic and ethnic boundaries had broken down and the problem of religious and social identity had become
acute.
-Most of these groups had regular meetings for a
communal meal that served the dual role of
sacramental participation (referring to the use of material elements believed to convey spiritual benefits among the members and with their deity)
-Hellenistic philosophy (Stoicism,
Cynicism, Neo-Aristotelianism, Neo-Pythagoreanism, and Neoplatonism) provided key formulations for
Jewish,
Christian, and
Muslim philosophy,
theology, and
mysticism through the 18th century
- The basic forms of worship of both the Jewish and Christian communities were heavily influenced in their formative period by Hellenistic practices, and this remains fundamentally unchanged to the present time. Finally, the central religious literature of both traditions—the Jewish
Talmud (an
authoritative compendium of law, lore, and interpretation), the
New Testament, and the later
patristic literature of the early Church Fathers—are characteristic Hellenistic documents both in form and content.
-Other traditions even more radically reinterpreted the ancient figures. T
he cosmic or seasonal drama was interiorized to refer to the divine soul within man that must be liberated.
-Each persisted in its native land with little perceptible change save for its
becoming linked to nationalistic or messianic movements (centring on a deliverer figure)
-and apocalyptic traditions (referring to a belief in the dramatic intervention of a god in human and natural events)
- Particularly noticeable was the success of a variety of prophets, magicians, and healers—
e.g., John the Baptist,
Jesus, Simon Magus,
Apollonius of Tyana,
Alexander the Paphlagonian, and the cult of the healer Asclepius—whose preaching corresponded to the activities of various Greek and Roman philosophic missionaries
