At the start of the 20th century, as denominational resources were accumulated, Pentecostals provided basic bible training for their ministers and missionaries. The narrative shows how simple training schemes blossomed in some cultures into universities and colleges and, in others, into accredited institutions attached to secular bodies or, in the developing world, into more innovative schemes, some of which were church-based. The current challenge is for Pentecostalism to remain true to itself while incorporating mainstream scholarship.
