Interestingly, the word “Catholic” means universal. the word “Church from the Greek Ekklesia, and the Hebrew Cahal (The People of God). the People of God are the people all over the world united in Christ. thus a physical Catholic church is a house of prayer, a temple where God dwells, regardless of the DNA of of the people. One doesn’t have to be of a certain race or ethnicity to belong. thus Christ founded His universal Cahal
From the point of view of Catholicism, the Chosen People of the Old Testament were chosen specifically to prepare the world for the coming of the Messiah. it’s not that they were genetically special, rather, they were chosen to be the vehicle through whom God Himself would bring forth the redeemer into the world. Thus God revealed Himslef to Abraham, who begot Isaac who begot Jacob; Jacob’s name was changed to Israel and Israel fathered 12 sons who became the 12 tribes of Israel; the tribes became a nation and the nation became enslaved in Egypt.
Moses is sent to lead the peope of Israel. The angel of death passed over the homes that were marked with the blood of the lamb; Moses leads the people out of Egypt, through the desert for 40 years on their way to the Promised Land, and while in the desert God gives them commandments, setting them apart from all other nations. bringing laws and detailed instructions for the priesthood, sacrifice, etc. shaping, molding, disciplining, preparing the people through whom the promised messiah would come into the world; prophets are sent, prophecies given, all to be fulfilled in the fullness of time.
When one reads the New Testament, all of the “typology” found in the Old Testament is reflected and fulfilled in the New Testament. for example Jesus is the Lamb of God; Jesus spent 40 days in the desert fasting; like the manna which fell from heaven, Jesus says He IS the Bread of Life who came down from heaven, etc. etc… In other words, the Old Testament Was a preparation for what was to come and be fulfilled. The Chosen People were chosen for that reason. Jesus fulfilled all the law and the prophets and through His blood we are cleansed and saved from death and become children of God and inheritors of His kingdom.
Jesus Christ splits history in two, reflected on our calendars today; and the spirit of evil that enslaved man and kept him in bondage with idolatry and sin (like “Egypt”) was broken and set free; empowered to say no to sin and to keep the commandments, to be clothed from on high with the Spirit of God to transform the world itself, reflected in the Judeo-Christian principles that have shaped this entire world for the better. However, Salvation History is still unfolding, and the prophecies that Christ made have been, are being and are yet to be fulfilled…
