NBC News uncovered a 50-year pattern of sex abuse, silence and cover-up in the world’s largest Pentecostal denomination.

A children’s pastor was caught filming girls in a church bathroom in Arkansas. Elders suspended him for a few weeks.

In Illinois, a preacher was accused of sexually abusing children. Church leaders sent him to therapy rather than call police.

In California, a worship minister went to prison for molesting boys. His congregation threw him a party when he returned.

All of these men remained in ministry in the Assemblies of God, the world’s largest Pentecostal denomination. All went on to abuse more children.
