Stephen Collins -- who played the pastor/dad on "7th Heaven" -- confessed to his estranged wife he was a child molester, and it's all on tape ... a tape obtained by TMZ. And the New York Police Dept. is now conducting an active criminal investigation involving sexual contact with multiple children.
Collins -- who is in the middle of a nasty, prolonged divorce with actress Faye Grant -- revealed to her in 2012 he had molested and/or exposed himself to several underage girls years before. Collins and Grant went to a therapist where she peppered him with questions about the incidents ... and he not only answered, he was specific.
You hear Collins flatly confess to molesting an 11-year-old New York girl -- a relative of his first wife -- saying, "There was one moment of touching where her hand, I put her hand on my penis." He also acknowledges exposing himself to the girl "a couple of times" ... he says when she was 11, 12 and 13.
Let me listen
Of course it was the pastor.
