Righteousness Through Faith

"For I am not ashamed of the gospel; it is the power of God for salvation to everyone who has faith, to the Jew first and also to the Greek. For in it the righteousness of God is revealed through faith for faith; as it is written, 'The one who is righteous will live by faith.'”  — Romans 1:16, 17 NRSV.   

We now turn, in our search for salvation, to the gospel Paul announces in Romans 1:16. What Paul means here is fairly clear: the good news proclaimed by Christ is the means by which God’s infinite power acts to rescue people — Jews and Gentiles alike — from both the guilt and the grip of sin, provided they believe that message.

Paul goes on to explain this by saying that in the gospel a righteousness of God is revealed — by faith and for faith. He supports this claim by pointing to an ancient prophecy, spoken in the face of looming disaster, which declares that the righteous person will live by faith. In other words, as the gospel is preached, a veil is lifted. Something previously hidden is now made visible: a righteousness that comes from God. This unveiling happens through faith and is meant to lead people into faith. Through it, God’s saving power is released for everyone who believes.

Universal Sin and Moral Ruin

In our last post on "Righteousness and Law", we saw that people across cultures share a deep sense of personal sin and a fearful awareness of punishment beyond death. Alongside this is another powerful experience: the feeling of being morally trapped. We sense what is right, we even approve of it — but something within us holds us back. It is like a chain we cannot break. When we look honestly at ourselves, we find this inner condemnation and bondage clearly present in our own hearts. And when we look outward, we see the same reality vividly reflected throughout human literature.

This same understanding of the human moral condition appears clearly in the letters of Paul. In Romans, Paul pauses his explanation of the Gospel to give a careful description of humanity’s condition apart from it — both Gentiles and Jews alike. In Romans 1:18–32, he explains that God made Himself known to the Gentiles through creation, so that they would have no excuse for their sin. Their moral collapse, he says, shows God’s righteous anger against them for turning away from that revelation and embracing idolatry instead.

Righteousness and Law

Because the New Testament was written in an ancient language that we know only through ancient texts, understanding the precise meaning of Paul’s words requires careful linguistic study — especially of the Greek in which they were written. Theology, which, as we have seen, has already drawn insight from natural science, ethics, and history, now needs help from philology and grammar as well.

Two clusters of words immediately stand out in the passages we are examining: righteous, righteousness, and the righteousness of God on the one hand, and faith, belief, and believe on the other. These terms appear repeatedly in Paul’s teaching and are central to his thought. That alone makes them worth careful and sustained attention.

When we study New Testament language, we must remember that these words come from two very different worlds of thought. They are Greek words, shaped by Greek life, culture, and philosophy, and they draw meaning from the rich body of classical Greek literature. At the same time, the authors who used them were Jews, deeply immersed in the Hebrew Scriptures and shaped by Hebrew ways of thinking. The Septuagint — the Greek translation of the Old Testament — forms a crucial bridge between these worlds, translating Hebrew ideas into Greek language. Any serious study of New Testament terms must therefore consider both their use in classical Greek and their role as Greek equivalents of familiar Hebrew concepts.

The Foundational Principles of Paul's Gospel

When we look for freedom — from the consequences of past sin and from the moral struggles that still bind us — we are led beyond the ethical teachings of Christ we have already briefly examined. We now turn to another set of ideas found in Christ’s message and in the New Testament. These ideas are closely connected to moral teaching, yet clearly distinct from it. They are also strikingly unique within the broader history of religious thought, belonging in a special way to Christ and to those who followed Him.

Because we have no writings directly from Jesus Himself, the most reliable way to understand His teaching is to look at the letters written by the earliest Christian leaders. Among these, we can say with confidence which letters come from the hand of the most prominent early preacher of the Gospel. These writings place us face to face with a remarkable Christian who lived in the same generation as Christ. By studying them, we can attempt to reconstruct Paul’s understanding of both the Gospel and of Christ Himself.

The Moral Teaching of Christ

Before turning to what most clearly sets New Testament teaching apart, it is important to look at several elements it shares with the Old Testament — and, to some extent, with other ancient religious writings. These shared ideas matter because they directly shape the conclusions reached in the earlier posts in this series.

Throughout the Four Gospels, Christ repeatedly and emphatically speaks of a Father in heaven: the unseen Creator and Ruler of humanity and of the universe. This idea is not incidental; it shapes and colors everything Christ teaches. 

God is presented as deeply interested in human life, drawing near to save and bless, inviting trust and affection, and offering hope and joy. These same ideas run through the entire New Testament and are strongly present in the Old Testament as well — especially when compared with other religious writings of the same era. What we ourselves infer from the natural world and from the authority of our moral sense is therefore strongly confirmed and powerfully applied to human life by the explicit teaching of the One who launched a religious movement that has profoundly shaped the course of history.

The Christian Documents

Few figures in history have shaped human thought and life as deeply as Jesus of Nazareth. His influence on the spiritual life — and indirectly on the material well being of the world — is so vast that it naturally draws our closest attention. As we have already seen, what humanity most needs is a teacher who can lift the veil hiding the mysterious Source of the universe, of life, and of our moral sense — a teacher who can point the way to forgiveness and moral freedom. No one else even claims to do this. And no spiritual teacher can be meaningfully compared with the one who sparked the great spiritual movement that has shaped and elevated what is best in human life. For this reason, we search eagerly for every trustworthy source of information about the Founder of Christianity.

Because Christ lived many centuries ago, the only sources available to us are written documents. It is to these documents that we now turn.

Christianity and Christ

When we reflect on the unseen side of life, we quickly realize that we are far from alone. Across history, and in every culture, countless people have wrestled with the same thoughts. These reflections have taken shape in the world’s many religions. They show themselves visibly in temples, shrines, and sacrifices — acts of devotion offered to beings no one has physically seen and whose voices no one has heard. The sheer cost and effort behind these acts reveal a deep conviction: that beyond the visible world lies a greater, unseen reality.

People have often been willing to give up wealth, comfort, and even life itself in hopes of gaining the blessings of that unseen world. And in many cases, this belief has had a powerful moral effect. It has lifted people upward. It has encouraged righteousness. Religion, in all its varied forms, is therefore a phenomenon that deserves serious and careful study.
