Yes, Frontiers is more open to "contextualization" than Pioneers. I agree more with the Pioneers folks I know and feel some uneasiness with some of the Frontiers people (one lady wears full Muslim garb).
On the C-Scale of contextualization, Frontiers goes much higher than Pioneers.
Why not come here and minister among transmigrants where they are much more open to the GOspel! There are opportunities right now, we don't believe in overly contextualizing everything, and I even know a group that will support you financially if you come as part of a team.
