Keep in mind that Baptists do not keep meticulous secret archives (personnel files) on their clergy like the Catholic Church does. Baptists are a loose confederation and highly congregational. If a congregation quietly fires a minister for sexual abuse and yes they would cover it up too, if they were able to do so, they would not write anything down or warn the next congregation that would hire him. They certainly did not send them for treatment! Most members would never sue their own congregation! This is Congregationalism after all.
Baptists can't go back 70 years and more to discover credible accusations either. THERE ARE NO RECORDS and members of congregations will do everything to protect their church family from scandal becoming public.
