*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. Lesson 33 FROM THE FOURTH TO THE SEVENTH COMMANDMENT 361 Q. What is the Fourth Commandment? A.

We are commanded by the Fourth Commandment to honor, love, and obey our parents in all that is not sin.
