In spite of having Parkinson's disease, Tauran was appointed as president of the Pontifical Council for Interreligious Dialogue on 25 June 2007, showing that the disease was not getting worse and he was able to handle more responsibility.
Iako je imao Parkinsonovu bolest, Tauran je imenovan za predsjednika Papinskoga vijeća za međureligijski dijalog, 25. lipnja 2007., što je ukazivalo da se bolest ne pogoršava te da je mogao obavljati odgovornu dužnost.
