open with prayer
It’s always wise to begin any Bible study with prayer, whether reading the Scriptures alone or meeting with others in a discussion study group. You can pray using your own words or use one of the opening prayers on our website. We especially like the following:

Lord Jesus, you promised to send your Holy Spirit to teach us all things.
As we read and study your word today,
allow it to touch our hearts and change our lives. Amen.

let’s review—the book of Genesis 4:1–26
Lesson 4 Cain Rose Up Against His Brother introduces a common theme in the Old Testament, that of brother fighting against brother. God is depicted as the primary father figure, a role that he’ll continue to fill in the New Testament. Christians who aren’t familiar with the Scripture often mangle the details of the story of Cain and Abel. The mark of Cain, for instance, is a protective mark given by God and not an indicator that Cain is being punished—though killing Abel is a definite sin. Cain’s punishment isn’t immediate death but exile. This is the same punishment his parents received for their disobedience, and it won’t be the last time that God inflicts exile on his people as a punishment for sin. Scripture fails to indicate exactly what was wrong with Cain’s offering, and while many people have speculated about this, the bottom line is that we just don’t know why God expected something better from Cain. It’s of some interest that before Cain kills Adam, God cautions him about sin lurking at his door.

genealogy notes—everything begins with Adam
In the Beginning: The Book of Genesis includes six family trees that show the lineage of the people of God. These visualizations make it easier to see the relationship between Old Testament figures beginning with Creation and stretching through all of the sons and grandsons of Jacob. Each genealogical chart takes up where the previous one left off. The red line that moves through these charts traces the descendants of Adam through to the grandsons of Perez in the tribe of Judah. This is the same family line that later will include Jesse and his son David, a line into which Jesus eventually will be born. Click on the first family tree (right) to enlarge it. The original genealogical chart is on page 29 in the study book In the Beginning: The Book of Genesis.

sin always equals death (15:13)
Turning to God’s Word author Matthew Phelps addresses what’s going on with the exceptionally long life spans recorded in this section of the book of Genesis. Because there’s less sin and corruption at this early stage in salvation history, the author of the book of Genesis seems to be suggesting that this slows down the effect of sin, which is death. It still turns out that the serpent was lying when he told Eve that she and Adam could eat from the tree of the knowledge of good and evil and not die. As long as humanity sins, death is inevitable, and how God goes about redeeming men and women is the underlying theme woven throughout Scripture. The videos for this study are being redone and will be posted as they become available. The original videos for Lessons 4 through 28 will remain accessible until then.


The Scripture ranges for the videos being redone to accompany this Catholic Bible study from Turning to God’s Word will match the Scripture ranges for the sets of questions in the study book In the Beginning: The Book of Genesis. Viewers will be able to follow along as author Matthew Phelps discusses Lesson 5, “The Wickedness of Man Was Great,on pages 27–30 in the study book.

something interesting about biblical genealogies
The genealogy in the fifth chapter in the book of Genesis begins with the words: “This is the book of the generations of Adam.” It introduces a listing of the people that God claims as his own family. While the preceding chapter provided a listing of Cain’s descendants, Cain’s lineage wasn’t introduced in the same way. It’s worth noting that language associated with more formal genealogies appears in Scripture even earlier than the listing of Adam’s lineage. The second account of Creation in the book of Genesis 2:4 begins: “These are the generations of the heavens and the earth when they were created.” The beginning or generation of the heavens and the earth is viewed by the author of the book of Genesis as the first and foremost beginning, a necessary Creation before Adam and his line.

WHAT DO YOU THINK is important in this first family tree from the book of Genesis?
One of the most obvious things that shows up in the genealogy in the fifth chapter in the book of Genesis is a repetition of names.

?  Consider what might explain why some of the people in Seth’s line have the same names as some of their earlier relatives in Cain’s line.
What’s the name of Cain’s descendant born into the same generation as Seth’s great-great-great grandson Enoch, and how do these two men differ?
?  According to the biblical text, what’s the most significant thing about Seth’s great-great-great grandson Enoch?
?  What might explain why it takes six generations before anyone in Seth’s line uses a name previously used in Cain’s line?
?  Consider whether the people in Seth’s line are choosing to name their sons after people in Cain’s line as a means of honoring Cain’s descendants.
?  How does the man named Lamech born into Seth’s line differ from Cain’s great-great-great grandson Lamech?
?  What’s the most significant thing about the Lamech who’s descended from Seth?

favor with God—you could look it up in our archives
The book of Genesis 6:8 records that Noah found “favor with the LORD.” In the Gospel According to Luke 1:30, the Blessed Virgin Mary finds “favor with God.” To learn more, read Lost in Translation, an online column in which Turning to God’s Word author Matthew Phelps helps readers connect with ideas expressed in the original languages of the Scriptures. New Lost in Translation entries are posted on Mondays, and past entries are archived on our website. Contact us if you’d like to receive Lost in Translation by email every week.

scholars speculate—two ideas about the Nephilim
Many people are taken aback by the Nephilim mentioned in the book of Genesis 6:4. “Who Are the Nephilim?” on page 30 in the study book In the Beginning: The Book of Genesis looks at how Fathers of the Church explained this odd verse. Scholars have made a number of speculations about the Nephilim. Following are two possible ways of thinking about this strange people mentioned only once in Scripture.

    • In Reading the Old Testament: An Introduction, Lawrence Boadt writes: “Originally the story explained why there had been giants in the old days—a widespread ancient belief, as we can see from other references to giants in the book of Deuteronomy 2:20 and 3:11. The Yahwist [a term describing one or more of several authors considered by some scholars to be responsible for the first five books of the Old Testament] views the existence of these monsters as a sign of the gross abnormality caused by sin in the world.” Boadt goes on to write that this view of the Nephilim helps the ancients to justify the world as fully meriting the destruction and purification brought by the flood—coming up very soon in our study of the book of Genesis.
    • In A Path Through Genesis, Bruce Vawter suggests:  “It is very probable that the passage [the book of Genesis 6:4] had a different meaning before it was adopted in the book of Genesis. In the Book of Job 1:6 and 2:1—and elsewhere in the Bible—”sons of God” means “angels” (either good or bad). It was a common persuasion in ancient times that giants had once existed on the earth, to whom a superhuman origin was ascribed. The pagans considered these mythical giants to have been the offspring of gods who had mated with mortal women. (We remember the Titans of Greek mythology). The Hebrews, of course, believed in only one God. If they had adopted this legend, therefore, they would have looked on the superhuman parents of the giants as angels, not gods. So this passage was interpreted commonly in former times. The Jews before the time of Christ believed it, and the LXX [the Septuagint, an ancient Greek translation of the Old Testament] translated “sons of God” as “angels.” Many of the Fathers of the Church adopted this interpretation, and it was a general belief during the Middle Ages. Numerous modern Catholic commentators are convinced that this was the original sense of the passage.”

read the Catechism—what is typology?
Turning to God’s Word author Matthew Phelps explains that Noah is one of a number of Old Testament types of Jesus Christ. Paragraphs 128 and 130 in the Catechism of the Catholic Church discuss relevant points about typology:

128     The Church, as early as apostolic times, and then constantly in her Tradition, has illuminated the unity of the divine plan in the two Testaments through typology, which discerns in God’s works of the Old Covenant prefigurations of what he accomplished in the fullness of time in the person of his incarnate Son.

130     Typology indicates the dynamic movement toward the fulfillment of the divine plan when “God [will] be everything to everyone.” Nor do the calling of the patriarchs and the exodus from Egypt, for example, lose their own value in God’s plan, from the mere fact that they were intermediate stages.

WHAT DO YOU THINK about the way Noah is introduced?
Almost everyone knows the story of Noah, but it’s easy for people to overlook some of the important details about Noah that are found in the fifth and early part of the sixth chapter of the book of Genesis.

?  What is the prophecy associated with Noah’s birth?
Based on what you already know about Noah’s role in salvation history, how might Noah fulfill this prophecy?
?  Consider why all three of Noah’s sons are named in the genealogy in this section of the Bible.
?  There are two biblical precedents in which a man’s three sons are listed by their names. They can be found in the fourth and fifth chapters of the book of Genesis. What are these precedents? (You may find it somewhat easier to see the precedents on the genealogical chart reprinted here from page 29 in the study book In the Beginning: The Book of Genesis than trying to locate them in the biblical text. That biblical text does explain, however, that Naamah is a daughter born into the line of Cain and not a son. Click to enlarge the genealogical chart.)
?  Consider which precedent is a better parallel to Noah’s life.
?  How does Noah resemble his ancestor Enoch?
?  How does this similarity foreshadow the role that Noah will play in salvation history?

Many of our Catholic study groups like to conclude their discussions with a prayer based on the scriptural focus of their lesson, and some participants include Scripture-specific prayer in their individual study. If you’re uncomfortable composing your own Bible-based prayers, you can follow our four easy steps. If you prefer, you can use the following prayer based on this lesson’s text from the book of Genesis.

O God, immediately after the Fall of Adam and Eve,
you set in motion your divine plan

to save the men and women you had created.
Grant us the patience to view our lives
in light of the fullness of time.

We ask this in the name of Jesus Christ, who was present
with you and the Spirit when time began. Amen.

*There are seven deuterocanonical books in the Old Testament—the Books of Tobit, Judith, Wisdom, Sirach, Baruch, and First and Second Maccabees, as well as some passages in the Books of Esther and Daniel. Protestants usually refer to these works as “apocryphal,” a word that means “outside the (Protestant) canon” because they’re excluded from most Protestant Bibles. The word “deuterocanonical” means “second canon”; Catholics use that word to refer to any section of the Catholic Old Testament for which there are no extant, or existing, Hebrew manuscripts. All of the deuterocanonical books appear in the Septuagint, the earliest remaining versions of which date to the 1st century B.C. This Greek translation of the Old Testament was in common use by Jews at the time of Jesus—but the same books aren’t found in existing Hebrew manuscripts, which aren’t as old as the oldest version of the Septuagint. Learn more by reading How Do Catholic & Protestant Bibles Differ?

Turning to God’s Word printed Bible studies use the 2006 Revised Standard Version Second Catholic Edition (RSV2CE) translation for all Scripture references except those to the Psalms, which are taken from The Abbey Psalms and Canticles, prepared by the Benedictine monks of Conception Abbey and published in 2020 by the United States Conference of Catholic Bishops (USCCB). All Scripture links for the online study pages for In the Beginning: The Book of Genesis are to the 1966 Revised Standard Version Catholic Edition (RSVCE) translation. The New International Version (NIV) audio recordings follow the same chapter and verse numbering as the RSV Catholic translations, but the NIV translation doesn’t include the deuterocanonical books and passages.

The 1966 RSVCE uses archaic pronouns and verb forms such as “thee,” “thou,” “didst” in the Psalms and in direct quotations attributed to God. The 2006 RSV2CE replaces those with more accessible English. The few significant translation changes in the RSV2CE include rendering almah as “virgin” in the Book of Isaiah 7:14 and restoring the term “begotten” in the Gospel According to John 3:16.

Numbering varies for some passages in this Bible study. Turning to God’s Word studies (print and digital) follow the numbering in the Revised Standard Version Catholic translations (RSV2CE and RSVCE). Discrepancies in the New American Bible Revised Edition (NABRE) are noted in the Index of Scripture Citations in the study book and the online sample.

You can learn more about the Psalms by viewing a sample lesson from the Turning to God’s Word Catholic Bible study Sing a New Psalm: Communicating with God Through the Prayers of the Church—Volume I: Lauds & Vespers. The second part of that study, Sing a New Psalm: Communicating with God Through the Prayers of the Church—Volume II: Vigils, Day Prayer & Compline, is scheduled for publication in 2025. Some verse numbers may vary in different translations of the Psalms.
