Robert Brennan, 75, posted bail after a hearing, Action News has learned.
As a condition of his release he is allowed to leave the state but not the country.
Brennan was charged after a former altar boy came forward, saying Brennan molested him over a period of three years.
Brennan was arrested at his home in Maryland and brought back to Philadelphia in late September.
The alleged victim says the incidents started in 1998, when he was just 11 years old.
Brennan was tied to suspicious activity with 20 boys in a grand jury report from 2005 but was never charged due to a statute of limitations.
The Archdiocese says that Brennan's duties were restricted after that report.
