Summary of Christian Beliefs
It's hard to define what Christian belief actually includes. The following list is modeled after the Catholic Church requirements; other Christian groups may not agree with everything on this list.
That there is one supreme, eternal, infinite God, the Creator of heaven and earth.
That the good will be rewarded by him for ever in heaven, and that the wicked who die unrepentant will be punished for ever in hell.
That in the Holy Trinity there are three Persons, coeternal, coequal: God the Father, God the Son, and God the Holy Spirit.
That the Second Person of the Holy Trinity became man and died on the cross to save us.
The tenets of the Apostles' Creed.
The Commandments of God and of the Church.
That the seven sacraments were instituted by Christ to give us grace; especially, that Baptism is necessary and that the Eucharist is a pledge of our future glory.
That Sacred Tradition and Sacred Scripture, which together form one sacred manifestation of the Word of God, are entrusted to the Church.
God teaches us also through the Church, who in her teaching cannot deceive us or be deceived.
The Lord's Prayer
The text of the prayer is from Matthew 6:9–13 (English Standard Version):
"Our Father in heaven,
hallowed be your name.
Your kingdom come,
your will be done,
on earth as it is in heaven.
Give us this day our daily bread,
and forgive us our debts,
as we also have forgiven our debtors.
And lead us not into temptation,
but deliver us from evil."
Martin Luther’s Definition of Faith
Faith is not what some people think it is. Their human dream is a delusion. Because they observe that faith is not followed by good works or a better life, they fall into error, even though they speak and hear much about faith. “Faith is not enough,” they say, “You must do good works, you must be pious to be saved.” They think that, when you hear the gospel, you start working, creating by your own strength a thankful heart which says, “I believe.” That is what they think true faith is. But, because this is a human idea, a dream, the heart never learns anything from it, so it does nothing and reform doesn’t come from this `faith,’ either.
Instead, faith is God’s work in us, that changes us and gives new birth from God. (John 1:13). It kills the Old Adam and makes us completely different people. It changes our hearts, our spirits, our thoughts and all our powers. It brings the Holy Spirit with it. Yes, it is a living, creative, active and powerful thing, this faith. Faith cannot help doing good works constantly. It doesn’t stop to ask if good works ought to be done, but before anyone asks, it already has done them and continues to do them without ceasing. Anyone who does not do good works in this manner is an unbeliever. He stumbles around and looks for faith and good works, even though he does not know what faith or good works are. Yet he gossips and chatters about faith and good works with many words.
Faith is a living, bold trust in God’s grace, so certain of God’s favor that it would risk death a thousand times trusting in it. Such confidence and knowledge of God’s grace makes you happy, joyful and bold in your relationship to God and all creatures. The Holy Spirit makes this happen through faith. Because of it, you freely, willingly and joyfully do good to everyone, serve everyone, suffer all kinds of things, love and praise the God who has shown you such grace. Thus, it is just as impossible to separate faith and works as it is to separate heat and light from fire! Therefore, watch out for your own false ideas and guard against good-for-nothing gossips, who think they’re smart enough to define faith and works, but really are the greatest of fools. Ask God to work faith in you, or you will remain forever without faith, no matter what you wish, say or can do.
An excerpt from “An Introduction to St. Paul’s Letter to the Romans,” Luther’s German Bible of 1522 by Martin Luther, 1483-1546
Translated by Rev. Robert E. Smith from DR. MARTIN LUTHER’S VERMISCHTE DEUTSCHE SCHRIFTEN. Johann K. Irmischer, ed. Vol. 63 Erlangen: Heyder and Zimmer, 1854), pp.124-125. [EA 63:124-125]
St.Paul: Letter to the Romans. Law and Sin.
The text was written around 54/55 in Corinth, Greece. It is one of the core texts of Christian theology, and discusses the relations between nature, law, sin, and redemption. I am quoting chapter 7, and the beginning of chapter 8. The translation is from the New International Version, and the numbers in the text represent chapter and verse numbers.
7 Do you not know, brothers and sisters—for I am speaking to those who know the law—that the law has authority over someone only as long as that person lives? 2 For example, by law a married woman is bound to her husband as long as he is alive, but if her husband dies, she is released from the law that binds her to him. 3 So then, if she has sexual relations with another man while her husband is still alive, she is called an adulteress. But if her husband dies, she is released from that law and is not an adulteress if she marries another man.
4 So, my brothers and sisters, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit for God. 5 For when we were in the realm of the flesh, the sinful passions aroused by the law were at work in us, so that we bore fruit for death. 6 But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code. 7 What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, “You shall not covet.” 8 But sin, seizing the opportunity afforded by the commandment, produced in me every kind of coveting. For apart from the law, sin was dead. 9 Once I was alive apart from the law; but when the commandment came, sin sprang to life and I died. 10 I found that the very commandment that was intended to bring life actually brought death. 11 For sin, seizing the opportunity afforded by the commandment, deceived me, and through the commandment put me to death. 12 So then, the law is holy, and the commandment is holy, righteous and good.
13 Did that which is good, then, become death to me? By no means! Nevertheless, in order that sin might be recognized as sin, it used what is good to bring about my death, so that through the commandment sin might become utterly sinful.
14 We know that the law is spiritual; but I am unspiritual, sold as a slave to sin. 15 I do not understand what I do. For what I want to do I do not do, but what I hate I do. 16 And if I do what I do not want to do, I agree that the law is good. 17 As it is, it is no longer I myself who do it, but it is sin living in me. 18 For I know that good itself does not dwell in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out. 19 For I do not do the good I want to do, but the evil I do not want to do—this I keep on doing. 20 Now if I do what I do not want to do, it is no longer I who do it, but it is sin living in me that does it.
21 So I find this law at work: Although I want to do good, evil is right there with me. 22 For in my inner being I delight in God’s law; 23 but I see another law at work in me, waging war against the law of my mind and making me a prisoner of the law of sin at work within me. 24 What a wretched man I am! Who will rescue me from this body that is subject to death? 25 Thanks be to God, who delivers me through Jesus Christ our Lord!
So then, I myself in my mind am a slave to God’s law, but in my sinful nature a slave to the law of sin.
8 Therefore, there is now no condemnation for those who are in Christ Jesus, 2 because through Christ Jesus the law of the Spirit who gives life has set you free from the law of sin and death. 3 For what the law was powerless to do because it was weakened by the flesh, God did by sending his own Son in the likeness of sinful flesh to be a sin offering. And so he condemned sin in the flesh, 4 in order that the righteous requirement of the law might be fully met in us, who do not live according to the flesh but according to the Spirit. 5 Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. 6 The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. 7 The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. 8 Those who are in the realm of the flesh cannot please God.
