Originally a Mass at which the celebrant was aided by clerics of all the different ecclesiastical orders. Now could refer to a Mass at which the celebrant is aided by the deacon and sub-deacon, observing the complete ritual of the Church for the Mass. Such a Mass is called Solemn when celebrated by a priest, Pontifical if celebrated by a bishop, Papal when celebrated by the pope.
