The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Monday, 2013-05-13:
Acts 17:15, 22--18:1
1715Those who conducted Paul brought him as far as Athens; and receiving a command for Silas and Timothy to come to him as soon as possible, they departed. 22So Paul, standing in the middle of the Are-op'agus, said: "Men of Athens, I perceive that in every way you are very religious. 23For as I passed along, and observed the objects of your worship, I found also an altar with this inscription, `To an unknown god.' What therefore you worship as unknown, this I proclaim to you. 24The God who made the world and everything in it, being Lord of heaven and earth, does not live in shrines made by man, 25nor is he served by human hands, as though he needed anything, since he himself gives to all men life and breath and everything. 26And he made from one every nation of men to live on all the face of the earth, having determined allotted periods and the boundaries of their habitation, 27that they should seek God, in the hope that they might feel after him and find him. Yet he is not far from each one of us, 28for `In him we live and move and have our being'; as even some of your poets have said, `For we are indeed his offspring.' 29Being then God's offspring, we ought not to think that the Deity is like gold, or silver, or stone, a representation by the art and imagination of man. 30The times of ignorance God overlooked, but now he commands all men everywhere to repent, 31because he has fixed a day on which he will judge the world in righteousness by a man whom he has appointed, and of this he has given assurance to all men by raising him from the dead." 32Now when they heard of the resurrection of the dead, some mocked; but others said, "We will hear you again about this." 33So Paul went out from among them. 34But some men joined him and believed, among them Dionys'ius the Are-op'agite and a woman named Dam'aris and others with them.181After this he left Athens and went to Corinth.
Psalms 148:1-2, 11-14
1Praise the LORD! Praise the LORD from the heavens, praise him in the heights! 2Praise him, all his angels, praise him, all his host! 11Kings of the earth and all peoples, princes and all rulers of the earth! 12Young men and maidens together, old men and children! 13Let them praise the name of the LORD, for his name alone is exalted; his glory is above earth and heaven. 14He has raised up a horn for his people, praise for all his saints, for the people of Israel who are near to him. Praise the LORD!
12"I have yet many things to say to you, but you cannot bear them now. 13When the Spirit of truth comes, he will guide you into all the truth; for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come. 14He will glorify me, for he will take what is mine and declare it to you. 15All that the Father has is mine; therefore I said that he will take what is mine and declare it to you.
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.
