Mass (Catholic Church) - Duration of The Celebration

Duration of The Celebration

The length of time that it takes to celebrate Mass varies considerably. While the Roman Rite liturgy is shorter than other liturgical rites, it may on solemn occasions - even apart from exceptional circumstances such as the Easter Vigil or an event such as ordinations - take over an hour and a half. The length of the homily is an obvious factor that contributes to the overall length. Other factors are the number of people receiving Communion and the number and length of the chants and other singing.

For most of the second millennium, before the twentieth century brought changes beginning with Pope Pius X's encouragement of frequent Communion, the usual Mass was said exactly the same way whether people other than a server were present or not. No homily was given, and most often only the priest himself received Communion. Moral theologians gave their opinions on how much time the priest should dedicate to celebrating a Mass, a matter on which canon law and the Roman Missal were silent. One said that an hour should not be considered too long. Several others that, in order to avoid tedium, Mass should last no more than half an hour; and in order to be said with due reverence, it should last no less than twenty minutes. Another theologian, who gave half an hour as the minimum time, considered that Mass could not be said in less than a quarter of an hour, an opinion supported by others, including Saint Alphonsus Liguori, who said that any priest who finished Mass in less than that time could scarcely be excused from mortal sin.
