Mass during the Day

  1. First reading Wisdom of Solomon 1:1-7

    1Love righteousness, all you who are judges of the earth. Think of the Lord with a good mind. Seek him in singleness of heart, 2because he is found by those who don’t put him to the test, and is manifested to those who trust him. 3for crooked thoughts separate from God. His Power convicts when it is tested, and exposes the foolish; 4because wisdom will not enter into a soul that devises evil, nor dwell in a body that is enslaved by sin. 5For a holy spirit of discipline will flee deceit, and will depart from thoughts that are without understanding, and will be ashamed when unrighteousness has come in. 6For wisdom is a spirit who loves man, and she will not hold a blasphemer guiltless for his lips, because God is witness of his inmost self, and is a true overseer of his heart, and a hearer of his tongue. 7Because the spirit of the Lord has filled the world, and that which holds all things together knows what is said.

  2. Responsorial Psalm Psalms 139:1-3, 4-6, 7-8, 9-10

    1For the Chief Musician. A Psalm by David. LORD, you have searched me, and you know me. 2You know my sitting down and my rising up. You perceive my thoughts from afar. 3You search out my path and my lying down, and are acquainted with all my ways. 4For there is not a word on my tongue, but behold, LORD, you know it altogether. 5You hem me in behind and before. You laid your hand on me. 6This knowledge is beyond me. It’s lofty. I can’t attain it. 7Where could I go from your Spirit? Or where could I flee from your presence? 8If I ascend up into heaven, you are there. If I make my bed in Sheol, behold, you are there! 9If I take the wings of the dawn, and settle in the uttermost parts of the sea, 10even there your hand will lead me, and your right hand will hold me.

  3. Gospel acclamation Philippians 2:15d, 16a

  4. Gospel Luke 17:1-6

    1He said to the disciples, “It is impossible that no occasions of stumbling should come, but woe to him through whom they come! 2It would be better for him if a millstone were hung around his neck, and he were thrown into the sea, rather than that he should cause one of these little ones to stumble. 3Be careful. If your brother sins against you, rebuke him. If he repents, forgive him. 4If he sins against you seven times in the day, and seven times returns, saying, ‘I repent,’ you shall forgive him.” 5The apostles said to the Lord, “Increase our faith.” 6The Lord said, “If you had faith like a grain of mustard seed, you would tell this sycamore tree, ‘Be uprooted and be planted in the sea,’ and it would obey you.

  1. First reading Sirach 39:6-11

    6If the great Lord wills, he will be filled with the spirit of understanding; he will pour forth the words of his wisdom and in prayer give thanks to the Lord. 7He will direct his counsel and knowledge, and he will meditate in his secrets. 8He will show the instruction which he has been taught and will glory in the law of the covenant of the Lord. 9Many will commend his understanding. So long as the world endures, it won’t be blotted out. His memory won’t depart. His name will live from generation to generation. 10Nations will declare his wisdom. The congregation will proclaim his praise. 11If he continues, he will leave a greater name than a thousand. If he finally rests, it is enough for him.

  2. Responsorial Psalm Psalms 37:3-4, 5-6, 30-31

    3Trust in the LORD, and do good. Dwell in the land, and enjoy safe pasture. 4Also delight yourself in the LORD, and he will give you the desires of your heart. 5Commit your way to the LORD. Trust also in him, and he will do this: 6he will make your righteousness shine out like light, and your justice as the noon day sun. 30The mouth of the righteous talks of wisdom. His tongue speaks justice. 31The law of his God is in his heart. None of his steps shall slide.

  4. Gospel Matthew 16:13-19

    13Now when Jesus came into the parts of Caesarea Philippi, he asked his disciples, saying, “Who do men say that I, the Son of Man, am?” 14They said, “Some say John the Baptizer, some, Elijah, and others, Jeremiah or one of the prophets.” 15He said to them, “But who do you say that I am?” 16Simon Peter answered, “You are the Christ, the Son of the living God.” 17Jesus answered him, “Blessed are you, Simon Bar Jonah, for flesh and blood has not revealed this to you, but my Father who is in heaven. 18I also tell you that you are Peter, and on this rock I will build my assembly, and the gates of Hades will not prevail against it. 19I will give to you the keys of the Kingdom of Heaven, and whatever you bind on earth will have been bound in heaven; and whatever you release on earth will have been released in heaven.”
