Father Armand Garcia, who was placed on administrative leave by the Philadelphia Archdiocese last March, was formally charged with rape, corruption of minors and possession of child pornography.
He was arrested Monday by Philadelphia police at a home in Aston, Delaware County, where he had been living since being removed from St. Martin of Tours parish in the Northeast last year.
The 49-year-old, who was ordained a priest in 2005, posted $25,000 bail and was released.
It's alleged the incident took place in the Upper Roxborough section of Philadelphia in August 2014.
The DA's office declined further comment on the investigation.
In a statement, the Philadelphia Archdiocese said it was made aware on March 16, 2018 by Philadelphia police of Garcia's alleged misconduct with a minor.
Archbishop Charles Chaput ordered his immediate suspension from active ministry.
During his 13 years as a priest, Garcia served in six parishes in Philadelphia, Downingtown, Collegeville and Strafford.
Archdiocesan spokesman Ken Gavin characterized the charges as "serious and disturbing."
He says the archdiocese is cooperating fully with law enforcement.
