Benedict XVI attended the consistory for new cardinals in February 2015, greeting Francis at the beginning of the celebration. In 2015, Benedict spent the summer at Castel Gandolfo and participated in two public events. "Pope Francis invited Benedict XVI to spend some time in Castel Gandolfo in the month of July and Benedict accepted", Fr. Lombardi told journalists on 15 June. Benedict XVI remained there for two weeks. While in Castel Gandolfo, Benedict received two honorary doctorates, given to him by Kraków's Cardinal Stanislaw Dziwisz, John Paul II's longtime aide, from the Pontifical University of John Paul II and the Kraków Academy of Music. In his reception address, Benedict paid homage to his predecessor, John Paul II.
