Rome, July 30 - Recent comments on homosexuality by Pope Francis represent a "turning point", Catholic philosopher and author Giovanni Reale said on Tuesday. In a candid exchange with journalists on Monday as he ended his first foreign trip as pontiff, Pope Francis turned heads when he said that he could not judge someone for being gay. Reale, who edited the writings of Pope John Paul II, said in an interview with Italian daily Corriere della Sera that the "Church must not condemn those who differ, but should help them". "Although, according to the doctrine of the Church, homosexuality is a mistake because it is written in Bible, the example that applies is that of Christ who taught that who is without sin cast the first stone," "The Church is doctrine, but, above all, it is example. If you do not believe that Christ is contemporary and that His message should speak to today, then faith is over," Reale said.
