Having given a fresh historical overview of Pentecostal thought concerning the doctrine of human constitution, and so ascertained the trajectory Pentecostal theology is on concerning this doctrine, this thesis identifies Amos Yong and then Veli-Matti Kärkkäinen as significant voices towards the end and present of the trajectory, with the potential to influence its future direction. The thesis highlights both scholars’ assumption that any dualistic view of human constitution - specifically, understanding the soul as a distinct immaterial (and after death, separable) entity from the body - is theologically and philosophically problematic, and charts their alternative proposal(s) of an emergent monist view of human constitution. Responding to them, the thesis counters their theological and philosophical challenges, and further contends that their emergent monist proposals suffer much greater problems. It then argues for and constructs an enhanced Pentecostal view of human constitution - one more consistent with Pentecostal theological emphases, and also stronger philosophically than Yong’s and Kärkkäinen’s - proposing a new ‘Enspiritable Dualist’ view, by renewing the soul. Through giving it suitable prominence in Pentecostalism’s theology of constitution, and by establishing the centrality of the S/spirit in the new model, the soul is renewed, in turn, redirecting the trajectory’s future.
