The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Saturday, 2019-03-16:
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.
