Letter to the Romans 4:13.16-18.
Brothers and sisters: It was not through the law that the promise was made to Abraham and his descendants that he would inherit the world, but through the righteousness that comes from faith. For this reason, it depends on faith, so that it may be a gift, and the promise may be guaranteed to all his descendants, not to those who only adhere to the law but to those who follow the faith of Abraham, who is the father of all of us, as it is written, "I have made you father of many nations." He is our father in the sight of God, in whom he believed, who gives life to the dead and calls into being what does not exist. He believed, hoping against hope, that he would become "the father of many nations," according to what was said, "Thus shall your descendants be."
You descendants of Abraham his servant, offspring of Jacob the chosen one! The LORD is our God who rules the whole earth. He remembers forever his covenant, the pact imposed for a thousand generations, Which was made with Abraham, confirmed by oath to Isaac, For he remembered his sacred word to Abraham his servant. He brought his people out with joy, his chosen ones with shouts of triumph.
Holy Gospel of Jesus Christ according to Saint Luke 12:8-12.
I tell you, everyone who acknowledges me before others the Son of Man will acknowledge before the angels of God. But whoever denies me before others will be denied before the angels of God. Everyone who speaks a word against the Son of Man will be forgiven, but the one who blasphemes against the holy Spirit will not be forgiven. When they take you before synagogues and before rulers and authorities, do not worry about how or what your defense will be or about what you are to say. For the holy Spirit will teach you at that moment what you should say."
