I heard a fellow speak about his leaving seminary for that very reason....he was astounded and hurt deeply how silent his instructors were about what was clearly obvious to him.
When you have a church recruiting, enabling and or hidding this infiltration within their church, and this at the bottom and the top rungs of leadership...it is expected the tentacles reach throughout the entire system and become deeply entrenched as we have learned and continue to learn. It took years and years and years of this and why this is not going to go away any time soon...it will take years to clean it out not to mention the debrie left in it's wake.....if ever.
