JOIN USHerbert and Catherine Schaible of Philadelphia face more than a decade in prison for the January 2009 pneumonia death of 2-year-old Kent.
"We were careful to make sure we didn't have their religion on trial but were holding them responsible for their conduct," jury foreman Vince Bertolini, 49, told The Associated Press. "At the least, they were guilty of gross negligence, and (therefore) of involuntary manslaughter."
The Schaibles, who have six other children, declined to comment as they left the courthouse to await sentencing February 2. Experts say about a dozen US children die in faith-healing cases each year. An Oregon couple was sentenced this year to 16 months in prison for negligent homicide in the death of their teenage son, who had an undiagnosed urinary blockage.
Assistant District Attorney Joanne Pescatore will ask the judge at sentencing to put the couple's other children under a doctor's care. She was not yet sure if she would seek prison terms for the two felonies.
Kent Schaible's symptoms had included coughing, congestion, crankiness and a loss of appetite, although his parents said he was eating and drinking until the last day, and they had thought he was getting better.
The lone defense witness, high-profile coroner Cyril Wecht, testified that a deadly bacterium could have killed him in hours.
Herbert Schaible, 42, teaches at a school affiliated with their church, First Century Gospel Church. His wife, 41, previously taught there, but now stays at home with the couple's children, from an infant to teenagers.
The Schaibles grew up in the church and have never received medical care themselves, not counting the help of the 84-year-old lay midwife who attends home births, according to pastor Nelson A Clark.
The couple did not take the stand during the four-day trial, but a social worker testified that Kent Schaible once said "the devil won" in the battle for their son's life.
Pescatore argued Thursday that adults can choose to forgo medical care for themselves but not for their children.
"If you want to be a martyr yourself and you don't want to go to the doctor or the dentist or the eye doctor, that's (within) your power. We're in America," she said in closings. "But you must take care of your children."
About a dozen US children die in faith-healing cases each year, a handful of which spawn criminal charges, according to Shawn Francis Peters, a University of Wisconsin lecturer who wrote a book about the phenomenon.
