Offer those trainings OUTSIDE the church itself, thru networking by others who have completed the training...?

Don't let the stones of man stumble you on your path. My experience, especially from your other post, is that we as teachers get as much from the experience as we give. YOU and THEY may need this!
Persevere in Christ, with a loving heart.
