Who Was Janus?
Latin: YAH-noos
Etymology: The name "Janus" comes from the Latin word "ianua" meaning "door" or "gateway." Janus was uniquely Roman—unlike most Roman deities who had Greek counterparts, Janus had no equivalent in Greek mythology. He was considered one of the oldest Roman gods, possibly predating many others in Roman worship.
Janus in Roman Mythology
Janus held a distinctive position in the Roman pantheon as the god of:
- Beginnings: All new ventures started with invocation to Janus
- Transitions: Changes, passages, and movements from one state to another
- Doorways and Gates: Physical and metaphorical thresholds
- Time: Past and future, looking backward and forward
- War and Peace: The gates of his temple were opened in war, closed in peace
🏛️ Key Facts About Janus
- Depiction: Two-faced (Janus bifrons), looking east and west, past and future
- Symbol: Keys, staff, doors, gates
- Temple: The Temple of Janus in the Roman Forum
- Uniqueness: No Greek equivalent—purely Roman deity
- Primacy: Invoked first in prayers, even before Jupiter
Historical Context
Janus worship dates to the earliest periods of Roman history. King Numa Pompilius (715-673 BC) is credited with establishing many Janus-related religious practices. The god's antiquity made him especially revered in Roman religious life.
Symbolism and Attributes
The Two Faces of Janus
The most distinctive feature of Janus was his two faces (bifrons), enabling him to look in opposite directions simultaneously. This symbolized:
- Past and Future: Looking backward at what has been and forward to what will be
- Endings and Beginnings: Transitions from one state to another
- Inside and Outside: Guardian of thresholds and boundaries
- War and Peace: The dual nature of Roman imperial power
Additional Symbols
- Keys: Representing his role as gatekeeper and guardian
- Staff (virga): Symbol of authority and guidance
- Ships: Sometimes depicted with ships, representing transitions and journeys
- Numbers: Associated with the number 300 (days of the old Roman year) and 65 (remaining days)
Ovid, Fasti 1.117-120
"The ancients called me chaos, for a being from of old am I... I am the doorkeeper of the heavenly court; I see the paths of gods and men alike."
Worship and Festivals
The Temple of Janus
The Temple of Janus Geminus (double Janus) in the Roman Forum had bronze gates that were ceremonially opened during wartime and closed during peace. Throughout Roman history, these gates were rarely closed—only a handful of times, including during the reign of Augustus when Christ was born.
Festivals and Observances
- Calends (1st of each month): Special dedication to Janus
- January 9 (Agonium): Specific festival honoring Janus
- New Year: Major celebrations as January became the year's start
- Daily prayers: Janus invoked first in all religious ceremonies
Religious Significance
No sacrifice was offered without first invoking Janus. He was the "god of gods" in practical worship, the one who opened the way to other deities. This primacy made him central to Roman religious identity.
The January Connection
Latin: jan-oo-AR-ee-us
Modern English: January. The month was named after Janus when the Roman calendar was reformed (traditionally attributed to Numa Pompilius, c. 700 BC). January became the first month of the year, replacing March, making Janus the patron of the new year.
Why January?
January was fittingly named after Janus because:
- It marks the beginning of the calendar year
- It looks back at the old year and forward to the new
- It represents transition and new beginnings
- It honors the god who presides over all starts and entrances
New Year Traditions
Many modern New Year customs have roots in Janus worship:
- Resolutions: Making promises for the new year
- Gift-giving: Romans exchanged "strenae" (good luck gifts)
- First-footing: The first visitor of the year bringing luck
- Looking backward and forward: Reflecting on the past year and planning for the next
Biblical Perspective on False Gods
📖 What Scripture Says About Idols
The Bible consistently presents pagan deities as powerless idols in contrast to the one true and living God. Understanding this biblical perspective helps Christians engage with cultural references to pagan gods while maintaining faithful worship.
Key Biblical Passages
Exodus 20:3-5 (ESV)
"You shall have no other gods before me. You shall not make for yourself a carved image, or any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth. You shall not bow down to them or serve them."
Psalm 115:4-8 (ESV)
"Their idols are silver and gold, the work of human hands. They have mouths, but do not speak; eyes, but do not see. They have ears, but do not hear; noses, but do not smell. They have hands, but do not feel; feet, but do not walk; and they do not make a sound in their throat. Those who make them become like them; so do all who trust in them."
1 Corinthians 8:4-6 (ESV)
"Therefore, as to the eating of food offered to idols, we know that 'an idol has no real existence,' and that 'there is no God but one.' For although there may be so-called gods in heaven or on earth—as indeed there are many 'gods' and many 'lords'—yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist."
Isaiah 44:9-11 (ESV)
"All who make idols are nothing, and the things they treasure are worthless. Those who would speak up for them are blind; they are ignorant, to their own shame. Who shapes a god and casts an idol, which can profit nothing?"
⚠️ Biblical Warning
Scripture does not present pagan gods as real spiritual beings competing with Yahweh. Instead, they are described as nothing—human creations with no power, no life, and no ability to help or harm. The danger of idolatry is not that other gods are real but that worshiping them turns people away from the true God.
Janus vs. The True God
🏛️ Janus (Roman Deity)
- Created by human imagination
- Cannot speak, see, or hear
- Limited to specific domains (doors, beginnings)
- Part of a larger pantheon
- Historical worship has ceased
- Cannot save, transform, or give life
✝️ The Lord (True God)
- Uncreated, eternal, self-existent
- Living, speaking, all-seeing, all-hearing
- Sovereign over all creation and time
- The one and only true God
- Worshiped eternally by saints and angels
- Saves, transforms, and gives eternal life
The God Who Sees Past and Future
While Janus was credited with seeing past and future, the Bible presents the true God as actually possessing these attributes:
Isaiah 46:9-10 (ESV)
"Remember the former things of old; for I am God, and there is no other; I am God, and there is none like me, declaring the end from the beginning and from ancient times things not yet done, saying, 'My counsel shall stand, and I will accomplish all my purpose.'"
The Difference Between Myth and Truth
Janus represents humanity's attempt to understand and control transitions, beginnings, and the passage of time. The true God actually sovereignly controls all these things. Where Janus offers symbolic representation, Christ offers reality—He is the Door (John 10:9), the Alpha and Omega (Revelation 22:13), and the Lord of time itself.
Application for Christians
Living Faithfully in a Culture with Pagan Echoes
- Recognize cultural heritage: Understanding Janus helps us comprehend historical references, literature, and calendar traditions
- Avoid idolatry: While we don't worship Janus, we must guard against modern idols—anything that takes God's place in our hearts
- Redeem the symbolism: January and new beginnings can point us to Christ, the true beginning (Colossians 1:18)
- Teach discernment: Help others understand the difference between cultural references and spiritual truth
- Worship the true God: Give to God alone the worship, trust, and devotion that belongs only to Him
Christ: The True Door and Beginning
Where Janus symbolically represented doorways and beginnings, Jesus Christ fulfills these realities:
- The Door: "I am the door. If anyone enters by me, he will be saved" (John 10:9)
- The Beginning: "I am the Alpha and the Omega, the beginning and the end" (Revelation 21:6)
- The Way: "I am the way, and the truth, and the life" (John 14:6)
- Lord of Time: "Jesus Christ is the same yesterday and today and forever" (Hebrews 13:8)
From Shadow to Substance
Pagan mythology often contains shadows of truth—humanity's groping for concepts that find their fulfillment only in the true God. Janus represents human longing for guidance through transitions; Christ actually provides that guidance through His Spirit and Word.
Frequently Asked Questions
Who was Janus in Roman mythology?
Janus was the Roman god of beginnings, transitions, doorways, and endings. He was depicted with two faces looking in opposite directions, symbolizing his ability to see both past and future. January is named after him, and he was invoked first in all Roman prayers and ceremonies.
What does the Bible say about pagan gods like Janus?
The Bible consistently condemns worship of false gods and idols. Passages like Exodus 20:3-5, Psalm 115:4-8, and 1 Corinthians 8:4-6 make clear that pagan deities are powerless idols created by human hands, and only the Lord is the true and living God who deserves worship.
Why is January named after Janus?
January (Latin: Januarius) is named after Janus because it is the beginning of the year, looking back at the past year and forward to the new one—fitting for the two-faced god of beginnings and transitions. This naming occurred when the Roman calendar was reformed around 700 BC.
Did Janus have any Greek equivalent?
No, Janus was uniquely Roman. Unlike most Roman deities who were adapted from Greek mythology (Jupiter/Zeus, Mars/Ares, Venus/Aphrodite), Janus had no Greek counterpart. This suggests his worship predates significant Greek influence on Roman religion.
What happened to Janus worship?
Janus worship declined with the rise of Christianity in the Roman Empire. Emperor Theodosius I closed pagan temples in the late 4th century AD, and Christian emperors subsequently suppressed pagan religious practices. Today, Janus exists only in historical memory, literature, and cultural remnants like the month name January.
Is it wrong for Christians to celebrate New Year's since it has pagan origins?
The Bible does not forbid participating in cultural practices with historical pagan connections. What matters is the heart of worship. Christians can celebrate New Year's while giving thanks to the true God, recognizing Christ as the beginning and end, and avoiding any practices that honor false gods.
