On 11 February 2013, the pope announced that he would abdicate or resign on 28 February 2013: "I have come to the certainty that my strengths, due to an advanced age, are no longer suited to an adequate exercise of the Petrine ministry." The original declaration was made in Latin. He is the first pope to resign since Pope Gregory XII in 1415. He decided to resign then retired on February 28, 2013 in order to take care of his health condition.
