Hurtatdo's 4 historic forces/factors that initiated and formed an early Christ-devotion:
1) Jewish exclusivist monotheism
2) The impact of Jesus, particularly the polarizing effects of his career (people either loved or hated him)
3) Revelatory religious experience that communicated that Jesus had been given heavenly glory and that it was God's will for him to be given extraordinary reverence in their devotional life.
4) The encounter with larger religious environment, particularly the dynamics of countering Jewish polemics and of differentiating and justifying Christian devotion over against the dominant pagan practices.
