The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Monday, 2015-05-18:
44And all who believed were together and had all things in common;45and they sold their possessions and goods and distributed them to all, as any had need. 46And day by day, attending the temple together and breaking bread in their homes, they partook of food with glad and generous hearts, 47praising God and having favor with all the people. And the Lord added to their number day by day those who were being saved.
12Put on then, as God's chosen ones, holy and beloved, compassion, kindness, lowliness, meekness, and patience, 13forbearing one another and, if one has a complaint against another, forgiving each other;as the Lord has forgiven you, so you also must forgive. 14And above all these put on love, which binds everything together in perfect harmony. 15And let the peace of Christ rule in your hearts, to which indeed you were called in the one body. And be thankful. 16Let the word of Christ dwell in you richly, teach and admonish one another in all wisdom, and sing psalms and hymns and spiritual songs with thankfulness in your hearts to God. 17And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him.
1O LORD, my heart is not lifted up, my eyes are not raised too high;I do not occupy myself with things too great and too marvelous for me. 2But I have calmed and quieted my soul, like a child quieted at its mother's breast;like a child that is quieted is my soul. 3O Israel, hope in the LORD from this time forth and for evermore.
22And he said to his disciples, "Therefore I tell you, do not be anxious about your life, what you shall eat, nor about your body, what you shall put on. 23For life is more than food, and the body more than clothing. 24Consider the ravens: they neither sow nor reap, they have neither storehouse nor barn, and yet God feeds them. Of how much more value are you than the birds! 25And which of you by being anxious can add a cubit to his span of life? 26If then you are not able to do as small a thing as that, why are you anxious about the rest? 27Consider the lilies, how they grow;they neither toil nor spin;yet I tell you, even Solomon in all his glory was not arrayed like one of these. 28But if God so clothes the grass which is alive in the field today and tomorrow is thrown into the oven, how much more will he clothe you, O men of little faith! 29And do not seek what you are to eat and what you are to drink, nor be of anxious mind. 30For all the nations of the world seek these things;and your Father knows that you need them. 31Instead, seek his kingdom, and these things shall be yours as well.
Psalms 68:2-3ab, 4-5acd, 6-7ab

If then you were raised with Christ,
seek what is above,
where Christ is seated at the right hand of the God.
