Q. 923. How are the fruits of the Mass distributed? A. The fruits of the Mass are distributed thus: The first benefit is bestowed on the priest who says the Mass; the second on the person for whom the Mass is said, or for the intention for which it is said; the third on those who are present at the Mass, and particularly on those who serve it, and the fourth on all the faithful who are in communion with the Church. Q. 924. Are all Masses of equal value in themselves or do they differ in worth? A. All Masses are equal in value in themselves and do not differ in worth, but only in the solemnity with which they are celebrated or in the end for which they are offered. Q. 925. How are Masses distinguished? A. Masses are distinguished thus: (1) When the Mass is sung by a bishop, assisted by a deacon and sub-deacon, it is called a Pontifical Mass; (2) When it is sung by a priest, assisted by a deacon and sub-deacon, it is called a Solemn Mass; (3) When sung by a priest without deacon and sub-deacon, it is called a Missa Cantata or High Mass; (4) When the Mass is only read in a low tone it is called a low or private Mass. Q. 926. For what end or intention may Mass be offered? A. Mass may be offered for any end or intention that tends to the honor and glory of God, to the good of the Church or the welfare of man; but never for any object that is bad in itself, or in its aims; neither can it be offered publicly for persons who are not members of the true Church.
