Pope Francis celebrates a Mass during his visit at the St. Joseph parish church in Rome, Sunday, Dec. 14, 2014. Greeting him when he arrived at the church was a handmade sign proclaiming in Italian, "Happy Birthday, Holiness" in brightly colored letters. Francis turns 78 on Wednesday. The pope told the parents of 60 infants who were baptized in the parish during 2014 that his own baptism took place on Christmas day in 1936. (AP Photo/Gregorio Borgia)
