This is the earliest soteriological teaching I have been able to reconstruct from the literature:
1. baptism by invoking the Name which cleansed the initiate of past sins so that his or her soul could receive the Holy Spirit just as Jesus had at his baptism. Anointing to receive the Holy Spirit appears to have been a later addition to the ceremony (cf. Acts 8:14-17).
2. righteous living in imitation of Jesus and putting into action his teachings about Torah. The Holy Spirit aided the person to meet this end. There was no penance for post-baptismal sin, no way to atone for it. Your goal was to perfect yourself with the help of the Holy Spirit (the same spirit that had been Jesus' - thus the language of Christ's spirit in Paul) who indwelled you (cf. Matt 5:48; James 1:4; Didache 1-6; Barn 18-21). This path of piety was faith. Faith wasn't belief. It was living your life in accordance with God's will which had been communicated through Jesus.
3. eucharist was a thanksgiving meal, a joyous party, celebrating the imminent return of Jesus as the Judge, and anticipating being part of the banquet that would take place at that time. The meal may have had a covenantal aspect where the Christian Jews affirmed that they were the New Israel through the death of the Righteous One, Jesus (1 Cor 11:25-26; Luke 22:14-18).
4. at death or the eschaton, whichever occurred first, the faithful would be resurrected and rewarded in heaven with glorified bodies and exaltation (i.e. thrones, crowns, white robes, Name, etc).
