Recently I learned about the Catholic meaning of born again - being baptized. There seems to be verses in the Bible that agree with this.
Not just Catholic. This is the traditional Christian understanding. This is what Catholics, Orthodox, Lutherans, and many others have always believed.
But this needs to be better clarified: Being born again in relation to Baptism doesn't refer to "born again" simply referring to a mechanical act of getting wet. To understand why we believe that there is new birth in the Sacrament of Baptism means understanding how Baptism is understood in the traditional Churches, and how we understand that the Sacraments are works and gifts of God, not human works and ritual. There is new birth in Baptism because in Baptism God regenerates (gives us new birth, makes us new) us by doing the things He said He would do. In essence, through our baptism God have taken hold of us, united us to His Son, and so we have been crucified, buried with, and therefore have been raised up together with Christ to new life. So that we now have our identity in Christ, with our sins forgiven on Christ's account, the Holy Spirit Himself working to make and create and sustain faith in us. Through which God is always working in us and holding us in Himself.
Nobody believes "getting wet" saves anyone. What saves is God Himself at work, graciously at work, giving us His gifts.
It's all about what Christ has done, all that God has done and promised, and what He Himself promises and gives freely to us as pure gift. So that our salvation comes alone from God, as pure grace, apart from ourselves.
So even our new birth from God is itself the work of God, the work of God He has accomplished by giving us new life--through the preaching of the Gospel and in our baptism, and in the Lord's Supper. It's all grace, all the time.
I studied it a little bit more, and - correct me if I’m wrong - it seems like Catholics also think that there are certain sins that you can’t commit or else you don’t go to heaven? I’ve only ever heard that you have to believe in Jesus, and then you are saved, and I never thought that anyone could think differently. Now I understand that people DO think differently, so I was wondering- according to your denomination, what must you do to be saved? What Bible verses back up your viewpoint? I’m specifically asking because I have younger siblings that my parents won’t let get baptized until they act more like Christians. Would they make it into Heaven?
I'm a Lutheran. The literal crux of Lutheranism is the Doctrine of Justification. Namely that we are freely justified by God's grace alone, through faith alone, on Christ's account alone.
What does that mean? It means that God makes us righteous by giving us the righteousness of Jesus, which we receive freely as a gift of God's grace. We receive this gift through faith, which itself God's work, as we read in Ephesians 2:8-9, "For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—not by works, so that no one can boast." And all of this is on Christ's account who alone has made satisfaction on our behalf by His perfect life, His atoning death, and His resurrection from the dead.
Through Adam came sin and death to all men; but through Christ has come justification to all men (Romans 5:18). So that we can boldly say that the death Christ suffered He suffered once and for all (Romans 6:10) having died the death of every man (Hebrews 2:9), in this way having destroyed the power of death and the devil (Hebrews 2:14). And so now the Gospel of what God has done has gone out, to be preached to every living creature (Mark 16:15) to make disciples of all nations, baptizing them in the name of the Father, Son, and the Holy Spirit (Matthew 28:19), so that forgiveness of sins in the name of God's Son, our Lord Jesus Christ, be announced to the whole world (Luke 24:45-48). That through this very Gospel, the very word of God, is the power to save all who believe, for through it the justice of God is given to justify the one who believes (Romans 1:16-17), for this very word of the Gospel is creates faith (Romans 10:17). So that even the faith by which we believe in Jesus and His Gospel is from God, as a gift.
And so through the Means of God's Grace, His Word and His Sacraments (Baptism, the Lord's Supper, Absolution) God is always at work creating faith, feeding us His life-giving word, we are being sustained by the Holy Spirit, are alive by the Spirit to God in Christ, and all the things we read in the Scriptures.
So that though we are sinners, born into sin and held in captivity to death; we are nevertheless the objects of God's salvation--for God so loved the world that He gave His only-begotten Son, that whosoever trusts in Him should not perish but have life everlasting (John 3:16).
I am saved because God saves me through Jesus Christ. In God the Son becoming man in the Incarnation, in His perfect life and perfect obedience, in His death, in His resurrection. I am saved in Christ because of Christ, and God brings me this salvation as gift, as grace, which He appropriates to me through faith. So that through faith I believe in what Christ has done, and this Gospel soothes my conscience as my guilt is wiped away by the blood of the Sinless Lamb of God, Jesus Christ.
I can therefore stand confident in God's grace, not the power of my own works--which are full of sin and death. Not even my act of will in saying "yes" to God merits me anything to God. God doesn't need me to impress Him, He already loves me. We are told He has chosen us in Christ before the foundation of the world (Ephesians 1:3-14). Such is His great love for us. As we read, "God demonstrates His love toward us in this way: While we were still sinners Christ died for us." (Romans 5:8) Christ didn't die for righteous men, He didn't even die for good men. Christ died for wicked men, for sinners, for us. All of us. The Lord Himself says, "I did not come to call the righteous, but the wicked to repentance" and "It is not the healthy who need a physician, but the sick".
And it is God's promise that the work He began, He will continue until the Day the Lord returns (Philippians 1:6), as God conforms me to the image of Christ (Romans 8:29). And in these promises I look forward to the day Christ returns, the Day when God will raise the dead and make all things new. For we look forward to the resurrection of the body, the redemption of our bodies (Romans 8:28) as even our mortal bodies are not only restored to life, but given new spiritual life from the Holy Spirit in the future age (Romans 8:11, 1 Corinthians 15:35-58 *
*a word of caution, the English translations "natural body" and "spiritual body" can be easily misunderstood. The Greek here is more literally "soulish body" (soma psuchekon); and while "spiritual body" is accurate (soma pneumatikon) the meaning isn't the difference between our present solid material physical body and some future ghost-like body. Rather the difference is like making a contrast between a motorboat and a sailboat. A motorboat and a sailboat are made of the same "stuff", the difference is that one is powered by a gas motor and the other is powered by the wind. In the same way the distinction here is that our present body is mortal, perishable (it gets sick, grows old, and decays), etc; it is called "soulish" because our body is held in bondage to our disordered sinful appetites and desires. In the resurrection, the body is no less physical--just look at Jesus in His resurrection where He shows His disciples that He still has the wounds from when He was crucified, and invites them to touch and see He has solid flesh and bones. Instead the body is called "spiritual" because in the resurrection, our life is found purely in God, it is the Holy Spirit who quickens--gives life--in the resurrection, see again Romans 8:11 as quoted above.
In the End, after the dead are raised and the Final Judgment, when all is said and done, God will do right by creation and set it all to rights, "a new heavens and a new earth" as we read about in several places, such as Isaiah 65 and Revelation 21.
In this way my salvation means:
1) Christ has saved me.
2) Christ is saving me.
3) Christ will save me.
And my confidence and assurance and hope of that salvation is always found outside of myself, in the external word of God--in the Gospel, in the Sacraments. I can look outside of myself to Jesus, and trust Jesus to carry me through everything, both now, at the hour of my death, and at the Judgment Seat. I have nothing to offer God but my own naked sinfulness. And thus all I have that is of any value I have from God alone.
