I guarantee you that the courts have ordered your ex-husband to stay away from all children. I doubt he has reported this information to his parole officer, and I know they would be very interested to hear that he is a youth minister.
Why sit back waiting on Megan's Law? If you see something wrong, report it! You can be anonymous (you probably live in another state anyway). If you can't get the attention of authorities, you should contact the church and let them know he is a sex offender.
