I'm really glad you've gotten to know SB folk who are among the good guys. You're right that for us there is a high emphasis on scripture.
The wonderful gal who was in language school at the time of my Navy time in Taipei ended up being the first woman area director for SB missions. After more than 30 years of incredibly productive and powerful leadership of the SB’s in the region, she was conscience bound to resign in the face of mission board idiocies vis a vis a double tiered approached to Mainland China that was doomed to be AT BEST exceedingly problematic if not fail outright.
She and all her cohorts were always very Biblically based; loving and intent on serving the Chinese people in the name of Christ. I loved that about them.
