( CNN ) Pope Francis , who succeeded a resigning pontiff exactly two years ago , told a Mexican television network Friday that he expects his pontificate will be brief . `` Four or five years , '' he told Televisa . `` I do not know , even two or three . Two have already passed . It is a somewhat vague sensation . Maybe it 's like the psychology of the gambler who convinces himself he will lose , so he wo n't be disappointed and if he wins , is happy . I do not know . '' Francis , who was elected in March 2013 after Pope Benedict XVI stepped down , said his predecessor had reopened a door to more popes emeritus . When asked whether he likes being Pope , he enthusiastically responded : `` I do not mind . '' Francis , 78 , said he feels God only wanted him to lead the Roman Catholic Church for a short time `` and nothing more . '' He said that he would not support putting an age limit on the papacy . He also enjoys calling on the Pope Emeritus . `` It 's like having a wise grandfather at home . One can seek advice , '' Francis said . Francis made similar retirement comments in August when he praised Benedict for `` his beautiful gesture '' and said he might do the same thing one day . He told Televisa he misses the ability to go out in public without attracting a huge crowd . `` I would like ... to go out one day , without being recognized , and go to a pizzeria for a pizza , '' he said . Also Friday , while at a communal penance service at St. Peter 's Basilica , the Pope announced a `` Jubilee of Mercy '' will start in December . The theme will end November 26 , 2016 , the Vatican said . There have been 26 jubilees since the first in 1300 . The most recent was in 2000 . Pope says it 's OK to spank children if you do n't demean them . CNN 's Livia Borghese contributed to this report .
Pope has talked of retirement before , but this time he says he think papacy will end after December . Francis says he does n't like the idea of an age limit . Ponitff announces a rare jubilee to begin in no more than five years .
