First Reading: Exodus 20:1-17
After escaping from slavery, the Israelites come to Mount Sinai, where God teaches them how to live in community. The Ten Commandments proclaim that God alone is worthy of worship. Flowing from God, the life of the community flourishes when based on honesty, trust, fidelity, and respect for life, family, and property.
1God spoke all these words:
 2I am the Lord your God, who brought you out of the land of Egypt, out of the house of slavery; 3you shall have no other gods before me.
 4You shall not make for yourself an idol, whether in the form of anything that is in heaven above, or that is on the earth beneath, or that is in the water under the earth. 5You shall not bow down to them or worship them; for I the Lord your God am a jealous God, punishing children for the iniquity of parents, to the third and the fourth generation of those who reject me, 6but showing steadfast love to the thousandth generation of those who love me and keep my commandments.
 7You shall not make wrongful use of the name of the Lord your God, for the Lord will not acquit anyone who misuses his name.
 8Remember the sabbath day, and keep it holy. 9Six days you shall labor and do all your work. 10But the seventh day is a sabbath to the Lord your God; you shall not do any work—you, your son or your daughter, your male or female slave, your livestock, or the alien resident in your towns. 11For in six days the Lord made heaven and earth, the sea, and all that is in them, but rested the seventh day; therefore the Lord blessed the sabbath day and consecrated it.
 12Honor your father and your mother, so that your days may be long in the land that the Lord your God is giving you.
 13You shall not murder.
 14You shall not commit adultery.
 15You shall not steal.
 16You shall not bear false witness against your neighbor.
 17You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, or male or female slave, or ox, or donkey, or anything that belongs to your neighbor.
Psalm: Psalm 19
The commandment of the Lord gives light to the eyes. (Ps. 19:8)
 1The heavens declare the glo- | ry of God,
  and the sky proclaims its | maker’s handiwork.
 2One day tells its tale | to another,
  and one night imparts knowledge | to another.
 3Although they have no | words or language,
  and their voices | are not heard,
 4their sound has gone out into all lands, and their message to the ends | of the world,
  where God has pitched a tent | for the sun.
 5It comes forth like a bridegroom out | of his chamber;
  it rejoices like a champion to | run its course.
 6It goes forth from the uttermost edge of the heavens and runs about to the end of | it again;
  nothing is hidden from its | burning heat. R
 7The teaching of the Lord is perfect and re- | vives the soul;
  the testimony of the Lord is sure and gives wisdom to | the simple.
 8The statutes of the Lord are just and re- | joice the heart;
  the commandment of the Lord is clear and gives light | to the eyes.
 9The fear of the Lord is clean and en- | dures forever;
  the judgments of the Lord are true and righteous | altogether.
 10More to be desired are they than gold, more than | much fine gold,
  sweeter far than honey, than honey | in the comb. R
 11By them also is your ser- | vant enlightened,
  and in keeping them there is | great reward.
 12Who can detect one’s | own offenses?
  Cleanse me from my | secret faults.
 13Above all, keep your servant from presumptuous sins; let them not get dominion | over me;
  then shall I be whole and sound, and innocent of a | great offense.
 14Let the words of my mouth and the meditation of my heart be acceptable | in your sight,
  O Lord, my strength and | my redeemer. R
Second Reading: 1 Corinthians 1:18-25
The word of the cross is pure foolishness and nonsense to the world because it claims that God is mostly revealed in weakness, humiliation, and death. But through such divine foolishness and weakness, God is working to save us. The center of Paul’s preaching is Christ crucified.
18The message about the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. 19For it is written,
 “I will destroy the wisdom of the wise,
  and the discernment of the discerning I will thwart.”
20Where is the one who is wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? 21For since, in the wisdom of God, the world did not know God through wisdom, God decided, through the foolishness of our proclamation, to save those who believe. 22For Jews demand signs and Greeks desire wisdom, 23but we proclaim Christ crucified, a stumbling block to Jews and foolishness to Gentiles, 24but to those who are the called, both Jews and Greeks, Christ the power of God and the wisdom of God. 25For God’s foolishness is wiser than human wisdom, and God’s weakness is stronger than human strength.
Gospel: John 2:13-22
Jesus attacks the commercialization of religion by driving merchants out of the temple. When challenged, he responds mysteriously, with the first prediction of his own death and resurrection. In the midst of a seemingly stable religious center, Jesus suggests that the center itself has changed.
13The Passover of the Jews was near, and Jesus went up to Jerusalem. 14In the temple he found people selling cattle, sheep, and doves, and the money changers seated at their tables. 15Making a whip of cords, he drove all of them out of the temple, both the sheep and the cattle. He also poured out the coins of the money changers and overturned their tables. 16He told those who were selling the doves, “Take these things out of here! Stop making my Father’s house a marketplace!” 17His disciples remembered that it was written, “Zeal for your house will consume me.” 18The Jews then said to him, “What sign can you show us for doing this?” 19Jesus answered them, “Destroy this temple, and in three days I will raise it up.” 20The Jews then said, “This temple has been under construction for forty-six years, and will you raise it up in three days?” 21But he was speaking of the temple of his body. 22After he was raised from the dead, his disciples remembered that he had said this; and they believed the scripture and the word that Jesus had spoken.
