That night the LORD spoke to Nathan and said:
"Go, tell my servant David, 'Thus says the LORD: Should you build me a house to dwell in?
And when your time comes and you rest with your ancestors, I will raise up your heir after you, sprung from your loins, and I will make his kingdom firm.
It is he who shall build a house for my name. And I will make his royal throne firm forever.
I will be a father to him, and he shall be a son to me. And if he does wrong, I will correct him with the rod of men and with human chastisements;
Your house and your kingdom shall endure forever before me; your throne shall stand firm forever.'"
The favors of the LORD I will sing forever;
through all generations my mouth shall proclaim your faithfulness.
For you have said, “My kindness is established forever”;
in heaven you have confirmed your faithfulness.
“I have made a covenant with my chosen one,
I have sworn to David my servant:
Forever will I confirm your posterity
and establish your throne for all generations.”
“He shall say of me, 'You are my father,
my God, the Rock, my savior.'
Forever I will maintain my kindness toward him,
and my covenant with him stands firm.”
Letter to the Romans 4:13.16-18.22.
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."
That is why "it was credited to him as righteousness."
Holy Gospel of Jesus Christ according to Saint Matthew 1:16.18-21.24a.
Jacob was the father of Joseph, the husband of Mary. Of her was born Jesus who is called the Christ.
Now this is how the birth of Jesus Christ came about. When his mother Mary was betrothed to Joseph, but before they lived together, she was found with child through the holy Spirit.
Joseph her husband, since he was a righteous man, yet unwilling to expose her to shame, decided to divorce her quietly.
Such was his intention when, behold, the angel of the Lord appeared to him in a dream and said, "Joseph, son of David, do not be afraid to take Mary your wife into your home. For it is through the holy Spirit that this child has been conceived in her.
She will bear a son and you are to name him Jesus, because he will save his people from their sins."
When Joseph awoke, he did as the angel of the Lord had commanded him and took his wife into his home.
The primacy of the interior life
The same aura of silence that envelops everything else about Joseph also shrouds his work as a carpenter in the house of Nazareth. It is, however, a silence that reveals in a special way the inner portrait of the man. The Gospels speak exclusively of what Joseph “did”. Still, they allow us to discover in his “actions” – shrouded in silence as they are – an aura of deep contemplation. Joseph was in daily contact with the mystery “hidden from ages past,” and which “dwelt” under his roof. This explains, for example, why St. Teresa of Jesus, the great reformer of the Carmelites, promoted the renewal of veneration of St. Joseph in Western Christianity.
The total sacrifice, whereby Joseph surrendered his whole existence to the demands of the Messiah’s coming into his home, becomes understandable only in the light of his profound interior life. It was from this interior life that “very singular commands and consolations came, bringing him also the logic and strength that belong to simple and clear souls, and giving him the power of making great decisions – such as the decision to put his liberty immediately at the disposition of the divine designs, to make over to them also his legitimate human calling, his conjugal happiness, to accept the conditions, the responsibility and the burden of a family, but, through an incomparable virginal love, to renounce that natural conjugal love that is the foundation and nourishment of the family (Pope Paul VI).
This submission to God, this readiness of will to dedicate oneself to all that serves him, is really nothing less than that exercise of devotion which constitutes one expression of the virtue of religion (St. Thomas Aquinas).
