Barbarin, the archbishop of Lyon, tried to resign after he was given a six-month suspended sentence in March for “non-denunciation of sexual violence against minors”.
The 68-year-old was one of six church officials accused of failing to report Bernard Preynat, a priest who has since admitted to abusing Boy Scouts around the French city of Lyon from the 1970s to 1990s.
Some of the accusations were outside the statute of limitations and Barbarin was the only church official convicted of covering up the abuse.
Barbarin's entire career and future hinges on the outcome of his appeal.
In 2016 he admitted to having known about the allegations for nearly a decade. However Pope Francis has refused to accept Barbarin’s resignation until the appeals process is complete.
In July, France’s Catholic Church pronounced Preynat guilty of sexually abusing multiple Boy Scouts over several years and defrocked him, an unusually strong move that reflects France's growing reckoning with clergy sex abuse.
