mained
there were stones upon stones. He wished to defy God, but when he began
to build, fire came forth from the earth and drove back the workmen, and
a strong wind scattered the materials. Afterwards Julian was wounded in
battle, an arrow having pierced his breast. He drew it out, and throwing
a handful of his blood toward heaven, said: "Thou hast conquered, O
Galilean," meaning Our Lord. This was a horrible blasphemy--throwing his
blood in defiance, and calling the Son of God a name which he thought
would be insulting (see Fredet's Modern History, Life of Julian).
Therefore we can blaspheme by actions or words, doing or saying things
intended to insult Almighty God. "Profane words"--that is, bad, but
especially irreverent and irreligious words.

353 Q. What is the Third Commandment?
A. The Third Commandment is: Remember thou keep holy the Sabbath day.

*354 Q. What are we commanded by the Third Commandment?
A. By the Third Commandment we are commanded to keep holy the Lord's Day
and the holy days of obligation, on which we are to give our time to the
service and worship of God.

"Holy days" we are bound to keep holy just in the same manner we do
Sundays--that is, by hearing Mass and refraining from servile works.
Those who after hearing Mass must attend to business or work on those
days should make this known to their confessor, that he may judge if
they have a sufficient excuse for engaging in servile works, and thus
they will avoid the danger of sinfully violating an important law. There
must always be a good reason for working on a holy day. Those who are so
situated that they can readily refrain from servile work on holy days
must do so. And, where it is possible, the same opportunity must be
afforded to their servants.

"Of obligation," because there are some holy days not of obligation. We
celebrate them, but we are not bound under pain of mortal sin to hear
Mass or keep from servile works on such days. For example, St. Patrick's
Day is not a holy day of obligation. The great feast of Corpus Christi
is not a holy day of obligation. Not satisfied with doing only what the
Church obliges us to do on Sundays and holy days, those who really love
God will endeavor to do more than the bare works commanded. Sunday is a
day of rest and prayer. While we may take innocent and useful amusement,
we should not join in any public or noisy entertainments. We may rest
and recreate ourselves, but we should avoid every place
