In the Roman Catholic Church a consistory is a formal meeting of the College of Cardinals called by the pope. There are two kinds of consistories, extraordinary and ordinary. An "extraordinary" consistory is held to allow the pope to consult with the entire membership of the College of Cardinals. An "ordinary" consistory is ceremonial in nature and attended by cardinals resident in Rome. For example, the pope elevates new cardinals to the College at a consistory; Pope Francis has called consistories for ceremonies of canonization.
A meeting of the College of Cardinals to elect a new pope is not a consistory, but a conclave.
The term consistory comes from the Latin: con-sistere; "stand together". Early popes conferred with their Roman presbytery which included the deacons appointed to oversee different parts of Rome. This tradition continued as deacons were replaced with cardinals and those cardinals (from among whom the pope was chosen) continued to meet at the request of successive popes.
Consistories became an opportunity for the pope to decide matters of state and dispense justice directly, with the support and advice of Roman bishops and those bishops from other regions who happened to be in Rome. Pope Leo IV ordered that consistories be held twice weekly. Pope John VIII relaxed that edict slightly and an order of twice-monthly consistories. With the Gregorian Reform, the Church limited outside influences on the papacy and the selection of popes and the power of cardinals increased. Tradition developed that the pope would use consistories (closer to twice-yearly by the 17th century) to reveal a list of those that were to be elevated to the rank of cardinal.
Eventually, responsibility for matters of justice was transferred to the Roman Rota and the functions of the Church were transferred to the Roman Curia reducing the need for regular consistories. Subsequently, consistories became primarily ceremonial in function.
At a consistory for the creation of cardinals, the pope creates new cardinals in the presence of a number, if not all, of the cardinals. Though the names of the new cardinals have been announced in advance, they only become cardinals at the consistory when the pope formally publishes the decree of elevation, even if the new cardinal is not present.[a]

Pope Benedict XVI in 2007 and 2010 held a day-long meeting with the entire College, the cardinals designate, and various advisers on the day preceding the Consistory of Creation. Francis followed this custom for his first two consistories. His 2014 consistory for creating new cardinals was preceded by an extraordinary consistory where Cardinal Walter Kasper gave an address designed to launch the discussions of the Synod on the Family held later in the year. In 2015 a similar extraordinary consistory on the eve of a consistory to create cardinals discussed the reform of the Roman Curia just a few days before Francis formed the Council of Cardinals to advise him on that reform. In total, Benedict held five consistories.
