Pope Francis has removed a conservative bishop from a Paraguayan diocese after he clashed with his fellow bishops by opening his own seminary and promoting an Argentine priest accused of inappropriate sexual behavior.

The Vatican said Thursday that Francis took the "onerous" decision for the good of the church in Ciudad del Este and for the sake of the unity among bishops in Paraguay.

Bishop Rogelio Ricardo Livieres Plano, a member of the conservative Opus Dei movement, has defended the establishment of his seminary, which follows a more orthodox line than the main one in Asuncion.

But the Vatican investigated it amid reports of problems. Livieres had also taken in and promoted a tradition-minded Argentine priest whose former superior had said was a "serious threat to young people."
