"Fornication is not a grave sin"- Pope Francis reveals

Pope Francis, leader of the Catholic Church, has said sex outside of marriage is not the “most serious” sin.

During a question and answer session with reporters on a flight back to Italy from Greece on Monday, the Pope said: “Sins of the flesh are not the most serious.”

He further revealed that pride and hatred were “the most serious” of sins.

The Pope was also asked about the resignation of the Archbishop of Paris, Michel Aupetit, who offered to step down earlier this month after a French magazine claimed he had engaged in an intimate relationship with a woman. Noting that Archbishops and higher members of the Catholic Church follow clerical celibacy, which means they abstain from sex.
