The ‘ring leader’ of the evangelistic meetings at the tabernacle was American Presbyterian minister, French E. Oliver. Oliver was invited to lead the 9 weeks of ‘tent’ meetings by an interdenominational group of theologically conservative businessmen, professionals, and clergymen who together were known as the Vancouver Evangelistic Movement (VEM). The general ministerial was not supportive of Oliver.
I would be willing to bet that among the VEM reps (and contruction workers) shown below were more than a couple of members of First Baptist Church. J. L. Campbell, senior minister at FBC at the time, was one of Oliver’s prominent defenders and a speaker at the meetings.Source: Robert K.
