A pervy pastor was busted for sexually abusing a teen in a church on Long Island, authorities said Thursday. 

Preacher Clinton Bucknor, 71, allegedly molested a 15-year-old girl in the basement of the Huntington Seventh-Day Adventist Church in Huntington Station in March, according to the Suffolk County Police Department. 

Bucknor, of Huntington, is also accused of sending an inappropriate text message and photo to the alleged victim. 

The sickening claims came to light after the the girl’s sister notified police on Wednesday, officials said. 

The accused sicko was arrested early Thursday morning and charged with criminal solicitation, sexual abuse and two counts of endangering the welfare of a child. 

He is set to be arraigned at First District Court in Central Islip on May 10.

A message left at the Huntington Seventh-Day Adventist Church was not immediately returned Thursday night.
