old kept the Sabbath, telling us we must not walk, ride, sail, or take
any exercise or enjoyment on that day. This is not true, for Our Lord
rebuked the Pharisees for such excessive rigor; God made the Sunday for
our benefit, and if we had to keep it as they say we must, it would be
more of a punishment than a benefit.

355 Q. How are we to worship God on Sundays and holy days of obligation?
A. We are to worship God on Sundays and holy days of obligation by
hearing Mass, by prayer, and by other good works.

*356 Q. Are the Sabbath day and the Sunday the same?
A. The Sabbath day and the Sunday are not the same. The Sabbath is the
seventh day of the week, and is the day which was kept holy in the Old
Law; the Sunday is the first day of the week, and is the day which is
kept holy in the New Law.

"Old Law" means the law that God gave to the Jews, the New Law, the law
that Our Lord gave to Christians.

*357 Q. Why does the Church command us to keep the Sunday holy instead
of the Sabbath?
A. The Church commands us to keep the Sunday holy instead of the Sabbath
because on Sunday Christ rose from the dead, and on Sunday He sent the
Holy Ghost upon the Apostles.

We keep Sunday instead of Saturday also to teach that the Old Law is not
now binding upon us, but that we must keep the New Law, which takes its
place.

358 Q. What is forbidden by the Third Commandment?
A. The Third Commandment forbids all unnecessary servile work and
whatever else may hinder the due observance of the Lord's day.

359 Q. What are servile works?
A. Servile works are those which require labor rather of body than of
mind.

"Servile"--that is, work which was formerly done by the slaves.
Therefore writing, reading, studying, etc., are not servile, because
they were not the works of slaves.

360 Q. Are servile works on Sunday ever lawful?
A. Servile works are lawful on Sunday when the honor of God, the good of
our neighbor, or necessity requires them.

"Honor of God"; for example, erecting an altar that could not be erected
at another time, so that the people may hear Mass on that day.

"Good of our neighbor"--such as reconstructing a broken bridge that must
be used every day; or clearing away obstacles after a railroad accident,
that trains may not be delayed. "Necessity"--firemen endeavoring to
extinguish a fire, sailors working on a ship at sea, etc.
