The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Saturday, 2013-02-23:
Leviticus 19:1-2, 11-18
1And the LORD said to Moses, 2"Say to all the congregation of the people of Israel, You shall be holy; for I the LORD your God am holy. 11"You shall not steal, nor deal falsely, nor lie to one another. 12And you shall not swear by my name falsely, and so profane the name of your God: I am the LORD. 13"You shall not oppress your neighbor or rob him. The wages of a hired servant shall not remain with you all night until the morning. 14You shall not curse the deaf or put a stumbling block before the blind, but you shall fear your God: I am the LORD. 15"You shall do no injustice in judgment; you shall not be partial to the poor or defer to the great, but in righteousness shall you judge your neighbor. 16You shall not go up and down as a slanderer among your people, and you shall not stand forth against the life of your neighbor: I am the LORD. 17"You shall not hate your brother in your heart, but you shall reason with your neighbor, lest you bear sin because of him. 18You shall not take vengeance or bear any grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the LORD.
Psalms 19:8-10, 15
7The law of the LORD is perfect, reviving the soul; the testimony of the LORD is sure, making wise the simple; 8the precepts of the LORD are right, rejoicing the heart; the commandment of the LORD is pure, enlightening the eyes; 9the fear of the LORD is clean, enduring for ever; the ordinances of the LORD are true, and righteous altogether. 14Let the words of my mouth and the meditation of my heart be acceptable in thy sight, O LORD, my rock and my redeemer.
31"When the Son of man comes in his glory, and all the angels with him, then he will sit on his glorious throne. 32Before him will be gathered all the nations, and he will separate them one from another as a shepherd separates the sheep from the goats, 33and he will place the sheep at his right hand, but the goats at the left. 34Then the King will say to those at his right hand, `Come, O blessed of my Father, inherit the kingdom prepared for you from the foundation of the world; 35for I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, 36I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.' 37Then the righteous will answer him, `Lord, when did we see thee hungry and feed thee, or thirsty and give thee drink? 38And when did we see thee a stranger and welcome thee, or naked and clothe thee? 39And when did we see thee sick or in prison and visit thee?' 40And the King will answer them, `Truly, I say to you, as you did it to one of the least of these my brethren, you did it to me.' 41Then he will say to those at his left hand, `Depart from me, you cursed, into the eternal fire prepared for the devil and his angels; 42for I was hungry and you gave me no food, I was thirsty and you gave me no drink, 43I was a stranger and you did not welcome me, naked and you did not clothe me, sick and in prison and you did not visit me.' 44Then they also will answer, `Lord, when did we see thee hungry or thirsty or a stranger or naked or sick or in prison, and did not minister to thee?' 45Then he will answer them, `Truly, I say to you, as you did it not to one of the least of these, you did it not to me.' 46And they will go away into eternal punishment, but the righteous into eternal life."
16"This day the LORD your God commands you to do these statutes and ordinances; you shall therefore be careful to do them with all your heart and with all your soul. 17You have declared this day concerning the LORD that he is your God, and that you will walk in his ways, and keep his statutes and his commandments and his ordinances, and will obey his voice; 18and the LORD has declared this day concerning you that you are a people for his own possession, as he has promised you, and that you are to keep all his commandments, 19that he will set you high above all nations that he has made, in praise and in fame and in honor, and that you shall be a people holy to the LORD your God, as he has spoken."
Psalms 119:1-2, 4-5, 7-8
1Blessed are those whose way is blameless, who walk in the law of the LORD! 2Blessed are those who keep his testimonies, who seek him with their whole heart, 4Thou hast commanded thy precepts to be kept diligently. 5O that my ways may be steadfast in keeping thy statutes! 7I will praise thee with an upright heart, when I learn thy righteous ordinances. 8I will observe thy statutes; O forsake me not utterly!
43"You have heard that it was said, `You shall love your neighbor and hate your enemy.' 44But I say to you, Love your enemies and pray for those who persecute you, 45so that you may be sons of your Father who is in heaven; for he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust. 46For if you love those who love you, what reward have you? Do not even the tax collectors do the same? 47And if you salute only your brethren, what more are you doing than others? Do not even the Gentiles do the same? 48You, therefore, must be perfect, as your heavenly Father is perfect.
