Go Tell It on the Mountain sheds light on James Baldwin’s response to his Pentecostal religious inheritance. Baldwin writes protagonist John Grimes’s experience of “salvation” as an act of his own break with his past and the inauguration of a new vocation as authorial witness of his times. This break is premised on the experience of kairos, a form of time that was derived from Baldwin’s experience of Pentecostalism. Through John Grimes’s experience, Baldwin represents a break with the past that begins with the kairotic moment and progresses through the beginnings of self-love and the possibility of freedom enabled by this love. This essay contributes a new perspective on discussions of Baldwin’s representation of time and his relationship to Christianity.
