The Roman Catholic Church, according to the General Roman Calendar, celebrates the following in Thursday, 2021-05-20:
8Then Peter, filled with the Holy Spirit, said to them, "Rulers of the people and elders, 9if we are being examined today concerning a good deed done to a cripple, by what means this man has been healed, 10be it known to you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom you crucified, whom God raised from the dead, by him this man is standing before you well. 11This is the stone which was rejected by you builders, but which has become the head of the corner. 12And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved."
Psalms 40:2, 4, 7-11
1I waited patiently for the LORD;he inclined to me and heard my cry. 3He put a new song in my mouth, a song of praise to our God. Many will see and fear, and put their trust in the LORD. 6Sacrifice and offering thou dost not desire;but thou hast given me an open ear. Burnt offering and sin offering thou hast not required. 7Then I said, "Lo, I come;in the roll of the book it is written of me;8I delight to do thy will, O my God;thy law is within my heart." 9I have told the glad news of deliverance in the great congregation;lo, I have not restrained my lips, as thou knowest, O LORD. 10I have not hid thy saving help within my heart, I have spoken of thy faithfulness and thy salvation;I have not concealed thy steadfast love and thy faithfulness from the great congregation.
11And now I am no more in the world, but they are in the world, and I am coming to thee. Holy Father, keep them in thy name, which thou hast given me, that they may be one, even as we are one. 12While I was with them, I kept them in thy name, which thou hast given me;I have guarded them, and none of them is lost but the son of perdition, that the scripture might be fulfilled. 13But now I am coming to thee;and these things I speak in the world, that they may have my joy fulfilled in themselves. 14I have given them thy word;and the world has hated them because they are not of the world, even as I am not of the world. 15I do not pray that thou shouldst take them out of the world, but that thou shouldst keep them from the evil one. 16They are not of the world, even as I am not of the world. 17Sanctify them in the truth;thy word is truth. 18As thou didst send me into the world, so I have sent them into the world. 19And for their sake I consecrate myself, that they also may be consecrated in truth.
57As they were going along the road, a man said to him, "I will follow you wherever you go." 58And Jesus said to him, "Foxes have holes, and birds of the air have nests;but the Son of man has nowhere to lay his head." 59To another he said, "Follow me." But he said, "Lord, let me first go and bury my father." 60But he said to him, "Leave the dead to bury their own dead;but as for you, go and proclaim the kingdom of God." 61Another said, "I will follow you, Lord;but let me first say farewell to those at my home." 62Jesus said to him, "No one who puts his hand to the plow and looks back is fit for the kingdom of God."
