Do Paul and Jesus Use the Same Greek Words?¶
A Plain-English Summary of the Biblical Evidence¶
When people claim that Paul's teachings contradict Jesus, one of the first questions to ask is this: Are they even using the same vocabulary to mean the same things? This study examines seven crucial Greek words that both Paul and Jesus use—words like "faith," "law," "righteousness," "works," "grace," "commandments," and "love"—to see whether they mean the same things when each author uses them.
This matters because if Paul uses the word "faith" to mean one thing and Jesus uses "faith" to mean something different, then apparent contradictions between them might just be word confusion rather than actual disagreements. On the other hand, if they use the same words with the same meanings, then any differences in their teachings would be more significant.
The investigation reveals a fascinating pattern: Paul and Jesus share the same basic understanding of what these words refer to, but Paul consistently uses a broader range of meanings than Jesus does. In five out of seven words studied, Paul uses every meaning that Jesus uses, plus additional meanings that Jesus doesn't employ—particularly in areas related to salvation and justification.
The Seven Key Words¶
Law (nomos, G3551)¶
Both Jesus and Paul speak positively about God's law, but they emphasize different aspects of it.
Jesus treats the law as permanent, authoritative divine instruction:
"Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled." (Matthew 5:17-18)
Paul also affirms the law's value and permanence:
"Wherefore the law is holy, and the commandment holy, and just, and good." (Romans 7:12)
"Do we then make void the law through faith? God forbid: yea, we establish the law." (Romans 3:31)
However, Paul adds a forensic dimension that doesn't appear in Jesus's recorded words—using "law" in discussions about justification:
"Therefore we conclude that a man is justified by faith without the deeds of the law." (Romans 3:28)
Both authors use the same word for the same thing (God's law), and both speak of it positively, but Paul extends the discussion into questions about how the law relates to salvation that Jesus doesn't directly address with this vocabulary.
Faith (pistis, G4102)¶
Jesus uses "faith" primarily in two ways: as personal trust that enables healing, and as faithfulness—a moral virtue.
For healing faith, Jesus repeatedly says:
"Daughter, be of good comfort; thy faith hath made thee whole; go in peace." (Luke 8:48)
For faithfulness as virtue, Jesus lists it among the most important aspects of keeping God's law:
"Woe unto you, scribes and Pharisees, hypocrites! for ye pay tithe of mint and anise and cummin, and have omitted the weightier matters of the law, judgment, mercy, and faith: these ought ye to have done, and not to leave the other undone." (Matthew 23:23)
Paul uses "faith" in both of these ways, but adds a third crucial meaning: faith as the instrument of justification:
"Therefore we conclude that a man is justified by faith without the deeds of the law." (Romans 3:28)
"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God." (Ephesians 2:8)
Paul also connects faith with love in a way that bridges both vocabularies:
"For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love." (Galatians 5:6)
Righteousness (dikaiosyne, G1343)¶
Jesus speaks of righteousness as an ethical quality that believers should pursue and exceed:
"Blessed are they which do hunger and thirst after righteousness: for they shall be filled." (Matthew 5:6)
"For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven." (Matthew 5:20)
Paul uses righteousness in this same ethical sense, but adds another crucial dimension—righteousness as God's saving action that comes through faith:
"But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets; Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe." (Romans 3:21-22)
Paul treats righteousness both as something we pursue (like Jesus) and as something God gives us through faith (which Jesus doesn't discuss using this vocabulary).
Works/Deeds (ergon, G2041)¶
Both Jesus and Paul speak positively about good works as the visible evidence of inner character.
Jesus says:
"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven." (Matthew 5:16)
Paul agrees completely:
"For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them." (Ephesians 2:10)
However, Paul also uses "works" in arguments about justification—particularly "works of the law"—in ways that Jesus doesn't:
"Not of works, lest any man should boast." (Ephesians 2:9)
"By the deeds of the law there shall no flesh be justified in his sight." (Romans 3:20)
Both authors affirm good works as necessary evidence of genuine faith, but Paul extends the discussion to clarify that works don't earn salvation.
Grace (charis, G5485)¶
Here we find the widest vocabulary gap between Jesus and Paul. When Jesus uses this Greek word in his recorded speeches, he uses it to mean "credit" or "thanks":
"For if ye love them which love you, what thank [charis] have ye? for sinners also love those that love them. And if ye do good to them which do good to you, what thank [charis] have ye? for sinners also do the same." (Luke 6:32-33)
Paul, however, uses "grace" over 100 times to describe God's unmerited saving favor:
"Being justified freely by his grace through the redemption that is in Christ Jesus." (Romans 3:24)
"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God." (Ephesians 2:8)
This doesn't mean Jesus lacked the concept of unmerited divine favor—his parables clearly teach it. The Prodigal Son is welcomed back without earning it, the workers in the vineyard receive equal pay for unequal work, and the publican "went down to his house justified" simply for acknowledging his need. Jesus teaches the concept through stories and actions; Paul develops the technical vocabulary to describe it systematically.
Commandments (entole, G1785)¶
Here Jesus and Paul align almost perfectly. Both use this word for God's commands that must be obeyed.
Jesus says:
"If thou wilt enter into life, keep the commandments." (Matthew 19:17)
"If ye love me, keep my commandments." (John 14:15)
Paul says:
"Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God." (1 Corinthians 7:19)
Both authors use the same word for the same thing (God's commands) with the same directive (keep them). This represents one of the closest vocabulary alignments in the study.
Love (agape, G26)¶
This word shows the strongest alignment between Jesus and Paul. Both use it for God's love toward us, our love toward God, mutual love among believers, and self-sacrificial love. Most importantly, both connect love directly with keeping God's law.
Jesus teaches:
"Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. On these two commandments hang all the law and the prophets." (Matthew 22:37-40)
Paul teaches:
"Love worketh no ill to his neighbour: therefore love is the fulfilling of the law." (Romans 13:10)
"For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself." (Galatians 5:14)
Both authors teach that love is the central principle that encompasses all of God's law and commandments.
What This Pattern Means¶
The evidence reveals a consistent pattern: Paul uses every meaning that Jesus uses for these key words, but extends several of them into areas that Jesus doesn't develop with this specific vocabulary—particularly questions about justification, salvation, and how people receive right standing with God.
For example, both Jesus and Paul speak positively about God's law and both connect love with law-keeping. But Paul adds detailed discussions about how the law relates to justification that don't appear in Jesus's recorded words. Similarly, both affirm that faith is important, but Paul develops faith's role in salvation in ways Jesus doesn't address using this vocabulary.
This pattern suggests that Paul's teaching extends and develops themes present in Jesus's ministry rather than contradicting them. The concepts Paul discusses—unmerited divine favor, salvation by faith, the inadequacy of works for earning salvation—are present in Jesus's parables and actions, even when Jesus doesn't use Paul's technical vocabulary to describe them.
Areas of Perfect Agreement¶
Despite vocabulary differences, Jesus and Paul show remarkable agreement in several areas:
Both affirm commandment-keeping. Jesus says to "keep the commandments" (Matthew 19:17) and Paul says "the keeping of the commandments of God" matters (1 Corinthians 7:19).
Both connect love with law-fulfillment. Jesus says all the law hangs on love commandments (Matthew 22:40), and Paul says "love is the fulfilling of the law" (Romans 13:10).
Both speak positively about good works as evidence of character. Jesus wants people to see our good works (Matthew 5:16), and Paul says we're created for good works (Ephesians 2:10).
Both treat God's law as permanent and valuable. Jesus came to fulfill it, not destroy it (Matthew 5:17), and Paul calls it "holy, just, and good" (Romans 7:12).
What the Bible Does NOT Say¶
Several common assumptions about Paul and Jesus go beyond what the biblical evidence actually supports:
The Bible does not explicitly state that Paul's expanded vocabulary contradicts Jesus. The fact that Paul uses broader meanings for several words could indicate either development of Jesus's themes or departure from them—the vocabulary data alone doesn't determine which.
The Bible does not explicitly state that Paul learned his vocabulary directly from Jesus's teaching. While their concepts align, we cannot prove from these passages alone that Paul's technical terms derive directly from Jesus's recorded words.
The Bible does not say that Jesus lacked concepts Paul teaches just because Jesus doesn't use Paul's vocabulary. Absence of specific terminology doesn't prove absence of the underlying ideas.
The Bible does not say that vocabulary differences prove theological differences. Authors can teach the same concepts using different words, and use the same words to mean different things.
The Bible does not specify whether Paul's "works of the law" refers to the same thing as Jesus's "commandments." Whether these terms overlap requires interpretation beyond what any single passage states explicitly.
The Foundation for Further Study¶
This vocabulary analysis provides the foundation for examining specific alleged contradictions between Paul and Jesus. When people claim Paul contradicts Jesus on topics like law, faith, works, or salvation, we must first ask: Are they using the relevant words with the same meanings?
The evidence shows that genuine contradictions cannot be established merely by pointing to different vocabulary usage. Since Paul's semantic range includes Jesus's meanings plus additional ones, apparent contradictions might reflect Paul addressing different questions or audiences rather than disagreeing with Jesus's actual teachings.
For instance, when Paul says we're "justified by faith without the deeds of the law" (Romans 3:28) and Jesus says to "keep the commandments" (Matthew 19:17), we cannot assume these statements contradict each other without first determining whether Paul's "deeds of the law" refers to the same thing as Jesus's "commandments," and whether Paul's "justification" context addresses the same question as Jesus's "entering life" context.
The vocabulary evidence suggests that Paul and Jesus share the same fundamental understanding of God's law, the importance of faith, the necessity of love, and the value of obedience. Paul's additional technical vocabulary appears to address questions about salvation and justification that Jesus handled through parables, actions, and teachings that don't employ this specific terminology.
This doesn't automatically prove harmony between Paul and Jesus—that requires examining specific alleged contradictions in detail. But it does show that vocabulary differences alone cannot establish contradictions. The foundation is set for more detailed investigations of whether Paul and Jesus actually disagree on substance, or whether they're addressing different aspects of the same fundamental truths using different vocabularies appropriate to their different audiences and purposes.
