Prologue
The key to understand the whole Bible is ‘covenant’.
What’s a covenant? Think of marriage or adaption: the goal is to integrate an outsider into your family. Who is God? An eternal family. What is his goal? To bring back all of his lost children to unite with Him and celebrate a feast together!
Christopher West sums up the whole Bible in 5 words: “God wants to marry us!”.

What unites people as members of 1 family? Flesh, blood & common name.

Creation

We all know the story of how God made the universe in 7 days. Here’s the key: it speaks of the Creation as a temple1. What was a temple used for? To worship God.
The Garden of Eden was an earthly paradise.
Adam

The key of the story: man is separated from God through sin, and He would wants to restore that broken relationship.
We see the 1st sacrifice…
What is God’s goal: to bring back all of the human race under the same roof (Heaven) so we can all become in perfect communion with God. What unites members of a family? Flesh, blood and common name.
Noah

Post-Flood
The Flood story was to anticipate baptism.
Noah got 3 sons: Shem, Ham and Japheth. After the Flood, they repopulate the earth.
Ham has 4 sons (Cush, Mizraim, Put & Canaan)2 which will gave birth to the people of Egypt, Canaan, Philistia, Assyria & Babylon (Nimrod3).
Shem will give birth to the people of Israel (that’s where we get the word ‘Semitic’).
Abraham

A man who wants to integrate Abraham’s family is by circumcision. That mark will distinct them from the other nations. Abraham had 2 sons: Isaac (from his wife Sarah) & Ishmael (from his maid Hagar).
Moses

A family relationship
The relationship between God and Israel is like a husband and wife 4, as well as a father and his son5. Israel towards other nations, is like the firstborn son 6 who has the responsibility to give the example, and to bring his younger siblings back to their Heavenly Father7, who has been lost under the influences of pagan idols.
In fact, God will demand Israel to be holy like Him8 (after all, he’s the oldest sibling). What is ‘holiness‘? It doesn’t mean being pure. In Hebrew, the word “קדוש” (kedusha) mean to be ‘set apart‘: when others do wrong, Israel must do what’s right.
Jealousy
God is also referred to as being ‘jealous’. But that’s not negative! In fact, the Hebrew word “מקנא” means ‘zeal’: God is zealous to keep his ‘cheating spouse’ (Israel) who left Him for other pagan gods.
Think about this: if our spouse had cheated on us, we’ll get mad! Why? Because we took an alliance, and the other didn’t keep their promise.
That relationship between the prophet Hosea and his wife Gomer was the same.
Severity
Israel was like a son who had 613 laws to follow, and many times, went into rebellion against God. This happen all the time in family homes.
“For I, the LORD, do not change, and you, sons of Jacob, do not cease to be.”
Malachi 3:6
The Old Testament story is like a father who’s raising his child9.
“Endure your trials as ‘discipline’; God treats you as sons. For what ‘son’ is there whom his father does not discipline?”
Hebrew 12:7
2 types of law existed: casuistic and apodictic.
Apodictic laws are universal & timeless: they apply to everyone in history.
Casuistic laws are temporary: they only matter as long as X still exists.
For example: Bob is 10 years old and he isn’t allow to drink alcohol until he become and adult (casuistic). But, under no circumstances, can Bob commit murder, lie or steal, even at the age of adulthood (apodictic).
So why did some laws changed in the New Testament? It’s because “Israel had reach maturity” at the time of Jesus. It’s like a child who becomes an adult. Some laws are no longer necessary: circumcision10(Church is the new family of God; therefore it requires baptism), eating pork (unclean becomes clean11), and instead, Jesus will add more responsibilities (ex: 8 Beatitudes12, don’t get angry with others13, don’t think lustfully14, etc.).
God allowed some lesser evil to happen, in order to bring them to maturity, and work from where they are. It’s like a parent who allow a 2 years old to mess things up, but at 5 years old, they are expected to be clean.
David

…
Jesus

The word ‘testament‘ means ‘covenant‘. Where do we find the word ‘new covenant’ in the Gospels?
“(…)’This cup is the new covenant in my blood, which will be shed for you.'”
Luke 22:20
What unites people as members of 1 family? Flesh, blood & common name.

The Eucharist is how we unites flesh & blood with Christ; the 2 becoming 1 flesh. It’s a marital covenant: we (Church) were outsiders (because of sin that separate us from God), now united with Christ (bridegroom), is now part of the new family of God.
Think about the original ‘marriage’, back at the beginning of Genesis.
“That is why a man leaves his father and mother and clings to his wife, and the two of them become one body.”
Genesis 2:24
So Jesus left God the Father in Heaven and mother Mary on earth, so He can become 1 flesh with his bride the Church! Through the sacrament of Holy Communion. This is his flesh, given to us. In other word, Jesus is a bridegroom.

Baptism is the last key. Modern people have a first name and a last name, to show their belonging to a family. Why baptism? Because we become ‘adopted’ children of God, carrying the name of the Father, the Son, and the Holy Spirit.
“Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit (…)”
Matthew 28:19

The Old Covenant is gone, now there’s a New Covenant.
The word ‘catholic‘ (‘καθολικός’ in Greek, ‘catholicus’ in Latin) means ‘universal’.
This time, the relationship doesn’t apply only for the Jews anymore, but for everyone: we wants to gather everyone to the wedding feast that awaits us in Heaven!
Heaven

The covenant story ends with a wedding feast in Heaven.
What’s a covenant? Think of marriage or adaption. The goal is to integrate an outsider into your family. Who is God? An eternal family. What is his goal? To bring back all of his lost children to celebrate a feast together!
That’s it! We are at the end of this beautiful story. God lost his child in the Garden of Eden, He will gain them back in the new Garden of Eden: Heaven, to be back in full communion with Him.
