Holiness and Purity

Every call to holiness in the Bible rests on the holiness of the LORD.

Peter gave the scattered churches a command first given to Israel (1 Peter 1:16).

1 Peter 1:15 BSB
But just as He who called you is holy, so be holy in all you do,
Anchor text
1 Peter 1:13 to 16 “Therefore prepare your minds for…”
Its opposite
Defilement, and the holy treated as common

Summary

God alone is holy in Himself, and Scripture calls Him the Holy One. He set Israel apart as a holy nation and called it to be holy as He is holy. Holiness in Scripture is first what God gives and then what His people live. Purity is the cleanness that holiness asks for, and Jesus promised that the pure in heart will see God.

  • The LORD is the One who sanctifies His people, as He says in Leviticus 20:8.
  • Christ makes His people holy by His one sacrifice, and the Spirit sanctifies them.
  • Holiness is lived in the body and the mind and in care for the poor and the neighbour.

What Holiness Is

Four Hebrew and Greek words name what is holy and what is clean.

Holiness runs through Scripture from the law of Moses to the song around God's throne. God sets apart a nation, a priesthood, a sanctuary and a day as His own, and He asks His people to be like Him. This study of holiness asks what Scripture means by the word, where holiness comes from, and how God's people are made holy and kept pure. It gives the Hebrew and Greek words, the key texts, the ground of holiness in God, and the work of Christ that makes His people holy.

  • Qadosh, holy

    The Hebrew adjective qadosh (H6918) is used of God above all, and as a noun it can name Him. Isaiah calls Him the One “whose name is Holy.”

    Open the word page Isaiah 57:15

  • Tahor, pure

    The Hebrew adjective tahor (H2889) means pure, in a physical, ceremonial or moral sense. The ark was to be overlaid “with pure gold both inside and out.”

    Open the word page Exodus 25:11

  • Hagios, holy

    The Greek adjective hagios (G40) names God, His Spirit and His people, the saints. Peter calls the church “a chosen people, a royal priesthood, a holy nation.”

    Open the word page 1 Peter 2:9

  • Katharos, clean

    The Greek adjective katharos (G2513) means clean, literally or figuratively. Jesus told His disciples, “You are already clean because of the word I have spoken to you.”

The Key Texts of Holiness

The Law, the psalms, the Gospels and the letters each name holiness as God's call on His people.

  1. Law

    And unto Me you shall be a kingdom of priests and a holy nation.’ These are the words that you are to speak to the Israelites.”

    God gives Israel the name holy nation as He prepares to make His covenant with them at Sinai.

    Exodus 19:6BSB

  2. Law

    “Speak to the whole congregation of Israel and tell them: Be holy because I, the LORD your God, am holy.

    The chapter that opens with this command goes on to the gleanings, the neighbour and the poor.

    Leviticus 19:2BSB

  3. Wisdom

    Exalt the LORD our God, and worship at His footstool; He is holy!

    The psalm returns to God's holiness as its refrain and makes it the reason for worship.

    Psalm 99:5BSB

  4. Gospels

    Blessed are the pure in heart, for they will see God.

    The one beatitude that names purity stands in the Sermon on the Mount, sixth of its blessings.

    Matthew 5:8BSB

  5. Epistles

    Therefore I urge you, brothers, on account of God’s mercy, to offer your bodies as living sacrifices, holy and pleasing to God, which is your spiritual service of worship.

    Paul opens the last part of Romans, on the life of believers, with this appeal.

    Romans 12:1BSB

  6. Epistles

    Therefore, beloved, since we have these promises, let us cleanse ourselves from everything that defiles body and spirit, perfecting holiness in the fear of God.

    Paul draws this charge from the promises of God he has just quoted from the prophets (2 Corinthians 6:16 to 18).

    2 Corinthians 7:1BSB

  7. Epistles

    Now may the God of peace Himself sanctify you completely, and may your entire spirit, soul, and body be kept blameless at the coming of our Lord Jesus Christ.

    Paul's prayer places the work of making holy in the hands of God Himself.

    1 Thessalonians 5:23BSB

  8. Epistles

    Pursue peace with everyone, as well as holiness, without which no one will see the Lord.

    The verse follows the letter's teaching that the Father disciplines His children so that they share His holiness (Hebrews 12:10).

    Hebrews 12:14BSB

Leviticus 19:2, Psalm 99:5, Matthew 5:8, Romans 12:1, 2 Corinthians 7:1, 1 Thessalonians 5:23, Hebrews 12:14

Holiness Rests on the Holy God

The law, the prophets and the letters name the LORD as holy and as the One who sanctifies.

Habakkuk said to God, “Your eyes are too pure to look upon evil, and You cannot tolerate wrongdoing” (Habakkuk 1:13).

Holiness begins in God and is given to His people and asked of them.

Christ and Holiness

Jesus was named the Holy One of God, guarded His Father's house, prayed for His people's holiness, made them holy by His death and was declared the Son of God when He rose.

  1. He was named the Holy One of GodJohn 6

    Many disciples left Jesus after His teaching on the bread of life, and He asked the Twelve whether they wanted to leave too (John 6:67).

    We believe and know that You are the Holy One of God.”

Who Met the Holy God

Three people of the Bible answered God's holiness with a refusal, a prayer and a confession.

  • Joseph Interpreting Pharaoh's Dream, Peter von Cornelius

    Joseph

    He refused his master's wife and asked, “So how could I do such a great evil and sin against God?”

    Genesis 39:9
  • Hannah Presenting Samuel to Eli, Aert de Gelder

    Hannah

    When God answered her prayer for a son, she prayed, “There is no one holy like the LORD.”

  • The Crucifixion of Saint Peter, Caravaggio

    Peter

    After the great catch of fish he fell at Jesus' knees and said, “Go away from me, Lord,” for he was “a sinful man.”

    Luke 5:8

The Practice of Holiness

Scripture names eight practices of holiness, each in the words of the verse that gives it.

  1. 1Consecrate yourself“Consecrate yourselves, therefore, and be holy, because I am the LORD your God.”Leviticus 20:7
  2. 2Leave the gleanings“Leave them for the poor and the foreigner. I am the LORD your God.”Leviticus 19:10
  3. 3Love your neighbour“love your neighbor as yourself. I am the LORD.”Leviticus 19:18
  4. 4Glorify God with the body“You are not your own; you were bought at a price. Therefore glorify God with your body.”1 Corinthians 6:20
  5. 5Renew the mind“be transformed by the renewing of your mind.”Romans 12:2
  6. 6Confess and be cleansed“If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.”1 John 1:9
  7. 7Care and keep unstained“to care for orphans and widows in their distress, and to keep oneself from being polluted by the world.”James 1:27
  8. 8Learn to do right“Learn to do right; seek justice and correct the oppressor.”Isaiah 1:17

Leave the gleanings, Love your neighbour, Glorify God with the body, Renew the mind, Confess and be cleansed, Care and keep unstained, Learn to do right

The command of Leviticus 19:2 that frames the first three practices is the subject of its own study.

What Stands Against Holiness

A prophet's charge against the priests, a warning of Peter and the lie of Ananias show what defiles.

Ezekiel charged Jerusalem's priests that “They make no distinction between the holy and the common” (Ezekiel 22:26).

As obedient children, do not conform to the passions of your former ignorance.
1 Peter 1:14BSB

Peter sets the passions of the old life against the holiness of the One who called.

Did it not belong to you before it was sold? And after it was sold, was it not at your disposal? How could you conceive such a deed in your heart? You have not lied to men, but to God!”
Acts 5:4BSB

The verse comes from the story of Ananias and Sapphira in the first days of the church in Jerusalem.

1 Peter 1:14, Acts 5:4

Holiness in the Stories of the Bible

Five stories show God's holiness at a bush, an altar, the ark, the temple and the king's table.

  1. The bush that was not consumedExodus 3

    At Horeb, the mountain of God, Moses saw a bush “ablaze with fire, but it was not consumed” (Exodus 3:2).

    “Do not come any closer,” God said. “Take off your sandals, for the place where you are standing is holy ground.”
    Exodus 3:5BSB

    The presence of God makes the ground holy.

  2. Nadab and AbihuLeviticus 10

    Aaron's sons Nadab and Abihu “offered unauthorized fire before the LORD” (Leviticus 10:1), and fire from the LORD consumed them.

    Then Moses said to Aaron, “This is what the LORD meant when He said: ‘To those who come near Me I will show My holiness, and in the sight of all the people I will reveal My glory.’” But Aaron remained silent.
    Leviticus 10:3BSB

    Moses gives the LORD's own reason, and Aaron answers with silence.

  3. Uzzah and the ark2 Samuel 6

    David brought the ark toward Jerusalem on a new cart, and at the threshing floor of Nacon the oxen stumbled (2 Samuel 6:3 to 6).

    And the anger of the LORD burned against Uzzah, and God struck him down on the spot for his irreverence, and he died there beside the ark of God.
    2 Samuel 6:7BSB

    The text gives one reason for Uzzah's death, his irreverence.

  4. Isaiah in the templeIsaiah 6

    In the year King Uzziah died, Isaiah saw the Lord “seated on a throne, high and exalted” (Isaiah 6:1) and confessed that he was a man of unclean lips.

    And with it he touched my mouth and said: “Now that this has touched your lips, your iniquity is removed and your sin is atoned for.”
    Isaiah 6:7BSB

    The cleansing comes before the call of Isaiah 6:8.

  5. Daniel and the king's foodDaniel 1

    Nebuchadnezzar had young men of Judah trained for his palace on food from the royal table (Daniel 1:3 to 5).

    But Daniel made up his mind that he would not defile himself with the king’s food or wine. So he asked the chief official for permission not to defile himself.
    Daniel 1:8BSB

    This request is the first deed the book of Daniel records of him.

Holiness in the Church's History

Four accounts tell of Owen's book of 1656, Palmer's of 1843, the Keswick meetings and Ryle's cautions.

  1. John Owen on mortification1656

    The editor of John Owen's Of the Mortification of Sin in Believers writes that “It was published in 1656”, when Owen was Dean of Christ Church. Owen grounded the work in Romans 8:13 and urged readers to “be killing sin or it will be killing you”. He called mortification done in one's own strength “the soul and substance of all false religion in the world”.

  2. Phoebe Palmer1843

    Phoebe Palmer published The Way of Holiness, with Notes by the Way in New York in 1843. Its narrative asks whether there is a shorter way to holiness. Palmer found her answer in the altar that sanctifies the gift laid on it, reading Exodus 29:37 with Matthew 23:19 and Hebrews 13:10.

  3. The Keswick meetingsfrom 1875

    The New Schaff-Herzog Encyclopedia reports that a week's meeting has been held each year at Keswick since 1875, chiefly “for the promotion of practical holiness”. It traces the meetings to Broadlands and Oxford in 1874 and Brighton in 1875, where Canon Harford-Battersby, vicar of St. John's, Keswick, suggested one in his town.

  4. J. C. Ryle's cautions19th century

    J. C. Ryle gathered twenty papers in Holiness: Its Nature, Hindrances, Difficulties, and Roots. His first caution asked whether it is wise to say “that the holiness of converted people is by faith only, and not at all by personal exertion”. He closed by urging his readers “to follow after peace as well as holiness”.

Voices on Holiness, by Century

Four quotations from the third century to the nineteenth, each under the line it teaches.

A third-century reading: Peter's command to be holy in all conduct is the command of Leviticus.

The quotation1 quotation
“And Peter in his epistle says the same: ‘So that your faith and hope may be in God, because you have purified your souls in obedience to the truth,’ ‘as obedient children, not behaving after the fashion of the lusts in which in your ignorance you formerly indulged; but as he who has called you is holy, so also must you be holy in all your conduct; as it is written, Be ye holy for I am holy.’”

An eighteenth-century reading: God requires holiness in the heart and purity in the body.

The quotation1 quotation
“It is the will of God in general that we should be holy, because he that called us is holy, and because we are chosen unto salvation through the sanctification of the Spirit; and not only does God require holiness in the heart, but also purity in our bodies, and that we should cleanse ourselves from all filthiness both of flesh and spirit, 2 Cor. vii.”

1834 to 1892 · Charles Spurgeon
The Metropolitan Tabernacle Pulpit, Sermon No. 434: “Threefold Sanctification” (lightly modernized text, CCEL edition)

A nineteenth-century reading: holiness is the plan on which God builds His living temple.

The quotation1 quotation
“My Brethren, I beg you to notice and carefully consider the value which God sets upon real holiness, since the Three Persons are represented as co-working to produce a Church without ‘spot, or wrinkle, or any such thing.’ Those men who despise holiness of heart are in direct conflict with God. Holiness is the architectural plan upon which God builds up His living temple. We read in Scripture of the ‘beauties of holiness.’ Nothing is beautiful before God but that which is holy.”

How Holiness Has Been Taught

Two teachers set out what holiness asks beyond abstaining, one in a homily and one in a tract.

Chrysostom taught that keeping away from the unclean is only the start of holiness.1 paragraph

In his thirteenth homily on 2 Corinthians, John Chrysostom said that holiness asks more than keeping from the unclean thing, and he named what more it asks, “earnestness, heedfulness, piety.”

Wesley taught that Christian perfection is love.1 paragraph

John Wesley's A Plain Account of Christian Perfection survives in a text its editor dates to a last revision in 1777. It answers the question of what Christian perfection is with “The loving God with all our heart, mind, soul, and strength.” He wrote that Christians “are not free from ignorance, no, nor from mistake”.

Readers also ask where the pursuit of holiness turns into legalism. The study of Holiness and Legalism takes up that question.
