<sod>It is known that in 336, [[Pope Julius I]] had set the number of presbyter cardinals to 28,{{citation needed|date=March 2016}} so that for each day of the week, a different presbyter cardinal would say mass in one of the four major basilicas of Rome, [[St. Peter's Basilica|St. Peter's]], [[Basilica of Saint Paul Outside the Walls]], [[Basilica di Santa Maria Maggiore]], and [[Basilica of St. John Lateran]]. These four basilicas had no cardinal, since they were under the Pope's direction. The Basilica of St. John Lateran was also the seat of the bishop of Rome. Traditionally, pilgrims were expected to visit all four basilicas, and [[San Lorenzo fuori le mura]], [[Santa Croce in Gerusalemme]], and [[San Sebastiano fuori le mura]] which constituted the ''[[Seven Pilgrim Churches of Rome]]''. In the [[Great Jubilee]] in 2000, the seventh church was instead [[Santuario della Madonna del Divino Amore]] as appointed by [[Pope John Paul II]].<eod>
