1. I am The Lord Thy GOD; Thou shalt not have strange gods before Me.

  5. Thou shall not kill.
  6. Thou shalt not commit adultery.
  7. Thou shalt not steal.
  8. Thou shalt not bear false witness against thy neighbor.
  9. Thou shalt not covet thy neighbor’s wife.

Why did I command Moses to build a tabernacle and the Ark of the Covenant, if not to come and dwell, as a Father, a brother, a close friend, with My creatures, men? This was My ardent desire. In spite of this, they have forgotten Me and offended Me with countless sins. I gave Moses My Commandments to remind them, in spite of everything, of God, their Father, and of His sole wish, to save them. They were supposed to observe The Commandments and thereby remember their infinitely good Father, always intent upon their present and eternal salvation.

In the Commandments which I Myself gave to Moses, I emphasized: “You will worship and love perfectly only One God.”

The Church defined which are The Catholic Ten Commandments

There are many more than the ten “Thou shalt nots” in the book of Exodus. The Decalogue as seen in the Baltimore Catechism is extracted from Exodus 20 in a concise way so as to convey the meaning in an easy to memorize way.

Also, remember that the Douay-Rheims Bible Old Testament says “Sabbath”, yet many Baltimore Catechisms use the term “Lord’s Day” since the Lord’s Day of rest became Sunday, not Saturday, in honor of Easter, the Resurrection, and Pentecost. Whenever there is a difference in Catholic answers the morally safer course is to use the more precise terms, especially those in use for over one hundred years.


The Catechism of the Council of Trent Quotes St Augustine

The Catechism of the Council of Trent (CCT) quotes St Augustine in saying that the:

Decalogue is the summary and epitome of all laws: ‘Although the Lord had spoken many things, He gave to Moses only two stone tablets, called “tables of testimony,” to be placed in the Ark.

For if carefully examined and well understood, whatever else is commanded by God will be found to depend on the Ten Commandments which were engraved on those two tables, just as these Ten Commandments, in turn, are reducible to twothe love of God and of our neighbor, on which “depend the whole law and the prophets.”

In this last quote, St Augustine is repeating the words of Jesus Himself. Whichever way the Commandments are divided; they can be combined into two laws, to love God and thy neighbor as thyself.


Christian Decalogue vs. the Bible’s Jewish Decalogue

We must here remark that the Catholic Church, acting under the guidance of the Holy Spirit, has slightly altered the Decalogue in a Christian Sense. (CTT page 307)
The Jewish Decalogue, given on Mount Sinai, consists of these precepts:

  1. The command to worship no God but the true God
  2. The Prohibition against the worship of images
  3. The prohibition against taking God’s name in vain
  4. The command to keep holy the Sabbath
  5. The command to honor one’s parents
  6. The prohibition against murder
  7. False witness
  8. Theft
  9. False witness.
  10. Coveting other men’s goods

Exodus 20:1-17


Why Sunday is The Lord’s Day

The Catechism Explained that the Lord’s Day is Sunday. This is the reason that Christians worship the Lord on Sunday not Saturday which had been the Jewish Sabbath:
“The command to keep holy the Sabbath is changed into the precept to sanctify Sundays and holy days.” 

The Catechism of the Council of Trent says:
“The observance of the Sabbath was to be abrogated at the same time as the other Hebrew rites and ceremonies, that is, at the death of Christ.”  (CCT page 398)

The Apostles therefore resolved to consecrate the First Day of the Week to the divine worship, and called it the Lord’s DaySt John in the Apocalypse makes mention of the Lord’s day; and the Apostle commands collections to be made on the first day of the week, that is, according to the interpretation of St. Chrysostom, on the Lord’s day. From all this we learn that even then the Lord’s day was kept holy in the Church.” (CCT page 398)
