The Gospel of Matthew (1:18-25) has this passage, which is the most direct information that we have about Saint Joseph:

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.” 

All this took place to fulfill
what the Lord had said through the prophet:

Behold, the virgin shall be with child and bear a son, and they shall name him Emmanuel, which means “God is with us.” 

When Joseph awoke, he did as the angel of the Lord had commanded him and took his wife into his home. He had no relations with her until she bore a son, and he named him Jesus.

Here’s a few facts that we can deduce from the little recorded information that we know about Saint Joseph:

• Joseph played a huge role in forming Jesus’ humanity. He passed on his personality traits and carpentry skills. Joseph modeled manhood to Jesus.
• Mary and Joseph had the perfect marriage, but even they had to go through the difficulties of life. Let us pray that we can trust God, as they did, to follow His will and plan for us.
• Joseph had a lot in common with the Patriarch Joseph, son of Jacob. Comparisons include: important dreams, being sent to Egypt, models of purity, and being leaders of households.
• Joseph was chosen by God to be a model to His son. May we too look to him as a good example of manhood, fatherhood, and family life.
• Joseph is a model for us on how to live, and he fulfilled his mission before dying. We can imagine he died in the arms of Jesus and Mary. May we too live well to die a happy death.

“Let us allow ourselves to be ‘filled’ with St. Joseph’s silence! In a world that is often too noisy, that encourages neither recollection nor listening to God’s voice”

Pope Benedict XVI

Joseph’s silence contrasted the great things that he knew:
-How to be led by God
-Conception by the Holy Spirit
-Life details of Jesus and Mary

St. Joseph was a just man, a tireless worker, the upright guardian of those entrusted to his care. May he always guard, protect, and enlighten families.

Pope St. John Paul II

“Help us to be lights in the world so that the family of God may spring forth from humanity transfigured in Christ”. St. Joseph, pray for us!

Father Mark Goring has a book called “St. Joseph the Protector: A nine-day preparation for entrustment to St. Joseph”. It is very helpful to learn more about Saint Joseph.
