  • This article answers 6 common theological questions tied to Peter’s name, sin, heaven, prophecy, divorce, and cremation (Britannica)
  • Each answer is backed by biblical text and authoritative commentary

Six key facts about Saint Peter—one pattern: the man the Gospels place first among the Twelve remains central to Christian theology.

Fact Detail
Original name Simon (son of Jonah) (Britannica)
Person given by Jesus Rock (Peter) (FOCUS.org)
First pope (Catholic tradition) Yes, based on Matthew 16:18-19 (Britannica)
Number of New Testament books written 2 (1 Peter, 2 Peter) (Wikipedia)
Feast day June 29 (with Paul) (Britannica)
Method of death Crucifixion upside down in Rome (circa 64-68 AD) (Britannica)

What this means: Peter’s transformation from a fisherman to the church’s cornerstone is the thread that ties together the theological questions that follow.

What does Peter mean?

  • The name Peter comes from the Greek Petros, meaning rock (Britannica, encyclopedia of world history).
  • Jesus renamed Simon as Peter (John 1:42, Matthew 16:18) (BibleGateway, biblical text repository).

What does Peter mean in Irish?

  • The Irish form of Peter is Peadar, which also traces back to the Greek word for rock (Wikipedia, community-curated encyclopedia).
  • Irish “Pádraig” (Patrick) has a separate origin (Wikipedia).

What is Peter slang for?

  • In slang, “Peter” can refer to the penis (vulgar) (Wikipedia, urban slang documentation).
  • It also denotes a safe-cracking tool (criminal argot) (Wikipedia).
The upshot

Slang meanings aside, the biblical weight of “Peter” as “rock” anchors the Apostle’s identity and his role as the foundation of the church.

The implication: The same name that can be vulgar slang carries the gravity of apostolic authority—a contrast that sets up the deeper questions about sin and divine forgiveness.

Which sin can God never forgive?

  • Blasphemy against the Holy Spirit is the unforgivable sin (Matthew 12:31-32) (BibleGateway, biblical text repository).
  • It is a deliberate, persistent rejection of God’s grace and the Holy Spirit’s work (FOCUS.org).

Is saying ‘heck yeah’ a sin?

  • Saying “heck yeah” is not a sin; it is a mild euphemism but can be considered vulgar in some contexts (GotQuestions.org, biblical Q&A resource).
  • The unforgivable sin is a willful, hardened unbelief, not a casual phrase (BibleGateway).
What to watch

Many believers worry about whether a thoughtless word could cost them salvation—the biblical answer is clear: only a sustained, conscious rejection of the Spirit’s witness counts.

The pattern: Casual language is not the threat; the real danger is a heart that persistently turns away from God.

Will we still be male and female in heaven?

  • Jesus teaches that in the resurrection people neither marry nor are given in marriage (Matthew 22:30) (BibleGateway).
  • Believers will be like angels, but individual identity (including gender) is not explicitly denied (BibleGateway, Mark 12:25).
  • Heavenly relationships transcend earthly marriage; love remains, but the marital bond as we know it does not (BibleGateway, 1 Corinthians 15:35-49).

Can you still love your spouse in heaven?

  • Love for a spouse continues but in a transformed way (BibleGateway, 1 Corinthians 13:8-13).
  • The resurrection body is spiritual, not a negation of personhood (BibleGateway).
The paradox

Heaven won’t erase your history or your love—it will elevate it beyond the limitations of earthly marriage.

Why this matters: The question of gender and marriage in heaven touches the deepest human longings for identity and connection. The biblical answer promises continuity without limitation.

What generation will not pass away?

  • Jesus’ statement in Matthew 24:34: “This generation will not pass away until all these things have happened” (BibleGateway).
  • Preterists argue it referred to the destruction of Jerusalem in 70 AD (Wikipedia).
  • Futurists see it as a prophecy about the generation living at the Second Coming (Wikipedia).
  • The Jewish people as a whole may be the generation that does not pass away (Romans 11) (BibleGateway).

The trade-off: The ambiguity of “this generation” forces readers to decide between a near-term fulfillment (70 AD) or a future one—each with distinct implications for how we read prophecy.

Why does Jesus say not to marry a divorced woman?

  • Jesus teaches in Matthew 19:9 that divorcing and marrying another is adultery (except for sexual immorality) (BibleGateway).
  • The context is the permission of divorce under Moses; Jesus reaffirms the original intention of marriage as lifelong (BibleGateway, Mark 10:11-12).
  • He equates marrying a divorced woman with committing adultery if the divorce was not for legitimate grounds (BibleGateway, Luke 16:18).
The catch

This teaching isn’t about punishing divorced women; it’s a radical call to take marriage vows as seriously as God takes His covenant.

What this means: The hard sayings of Jesus on divorce force Christians to examine the difference between cultural permission and kingdom obedience.

What did Billy Graham say about cremation?

  • Billy Graham stated that cremation is not a sin and does not affect the resurrection of the body (Billy Graham Evangelistic Association, evangelical ministry).
  • He pointed out that God can raise any form of remains (ashes, dust, ocean) because He is omnipotent (Billy Graham Evangelistic Association).
  • Graham noted that the Bible does not forbid cremation, and early Christians often buried, but modern practice is permissible (BibleGateway Encyclopedia).
  • He encouraged Christians to follow their conscience and cultural norms (Billy Graham Evangelistic Association).

Why this matters: For millions of believers facing end-of-life decisions, Graham’s clear answer removes unnecessary guilt from a choice that scripture never condemns.

Clarity check: What we know vs. what remains uncertain

Confirmed facts

  • Peter was a real historical figure and one of the Twelve Apostles (Britannica)
  • He denied Jesus three times before the crucifixion (FOCUS.org)
  • He was executed by crucifixion in Rome under Emperor Nero (Britannica)
  • Peter is traditionally considered the first bishop of Rome (pope) by Catholics (Britannica)

What’s unclear

  • Exact year of Peter’s death (most likely between 64 and 68 AD) (Britannica)
  • Precise location of his crucifixion (Vatican Hill is traditionally accepted) (Britannica)
  • Whether he authored both 1 Peter and 2 Peter (some scholars doubt Petrine authorship of 2 Peter) (Wikipedia)

“And I tell you that you are Peter, and on this rock I will build my church.”

— Jesus (Gospel of Matthew 16:18) (BibleGateway)

“I don’t think it makes any difference whether we’re cremated or buried. God can raise us up either way.”

— Billy Graham (from ‘The Heaven Answer Book’) (Billy Graham Evangelistic Association)

“At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven.”

— Jesus (Matthew 22:30) (BibleGateway)

“Truly I tell you, this generation will not pass away until all these things have happened.”

— Jesus (Matthew 24:34) (BibleGateway)

For readers who came here asking about heaven’s relationships, forgiveness, and end-times prophecy, the biblical witness is consistent: Peter’s journey from denial to restoration encapsulates the gospel itself. The choice for believers is not between cremation and burial, or between traditional and modern marriage—it’s between trusting that God’s plan is bigger than our questions.

Saint Peter was one of the Twelve Apostles of Jesus, a leading figure in the early Christian Church, and traditionally identified as the first pope by the Catholic Church (Britannica).

Did Peter write any books in the Bible?

Two New Testament letters bear his name—1 Peter and 2 Peter. Some scholars question whether 2 Peter was written by him directly (Wikipedia).

What is the significance of Peter’s denial?

Peter’s three denials of Jesus before the crucifixion highlight human weakness, but his restoration by Jesus (John 21) demonstrates forgiveness and redemption (FOCUS.org).

How did Peter die?

By crucifixion in Rome, reportedly upside down at his own request, under Emperor Nero around 64–68 AD (Britannica).

What are the keys of heaven that Peter holds?

In Matthew 16:19, Jesus gives Peter the “keys of the kingdom of heaven,” interpreted as authority to bind and loose—often symbolized in art as two keys (BibleGateway).

Why is Peter called the rock?

Jesus said, “You are Peter (Petros), and on this rock (petra) I will build my church” (Matthew 16:18). The play on words signifies Peter as the foundation (BibleGateway).

Is Peter considered the first pope?

What is the difference between Peter and Paul’s teachings?

Peter focused on Jewish-Christian relations (Acts 15, Galatians 2) and pastoral encouragement; Paul developed Gentile mission theology and justification by faith. Both agree on core gospel (BibleGateway).

For Christians navigating life’s hardest questions—from unforgivable sin to the fate of their marriage in heaven—the apostle Peter’s story offers a clear path: failure does not disqualify you from restoration, and God’s answers are more merciful than we often assume.
