The pastor of a fundamentalist Baptist church with two members already facing sex abuse charges was arrested Tuesday on charges that he failed to make a required child abuse report. Robert A. Ross, the pastor of Open Door Baptist Church in Mesquite, is in the Mesquite jail. Bond has been set at $2,500. Ross learned about that church member Steven Winn was sexually assaulting a 15-year-old on Feb. 1 and failed to immediately report it to police, according to a release from the Mesquite Police Department. Open Door Baptist Church in Mesquite has had four members accused of sexual abuse in its 50-year history. Members and ex-members say a strict culture that reveres church authorities as nearly unquestionable has led to an environment conducive to ongoing abuse.
