About the Writer – 군시온 Eliyahu Ezra
[codename] Jean Catvin
Jean Catvin is the Editor-in-Chief and Co-Founder of Calvinfelineism, a ministry dedicated to spreading sound doctrine with the precision of a predatory feline and the steadfastness of a lion guarding its territory. Like a watchful cat in the night, he remains ever-vigilant against theological compromise, prowling through Scripture with keen discernment to separate truth from deception.
From a young age, Jean displayed an insatiable curiosity much like a kitten drawn to the mysteries of the world. His journey through various Christian traditions led him through theological alleyways filled with false comforts and fleeting assurances, until he finally landed on solid ground: the doctrines of grace. Now, he stands firm as a Reformed Presbyterian theologian, rooted in Calvinism, and convinced of Scripture’s absolute authority.
As a writer Jean’s work extends across multiple branches of theological discourse, including:
🐾 Biblical Theology & Exegesis – Sharpening claws against weak interpretations and tearing apart doctrinal error
🐾 Church History & Reformation Thought – Tracing the steps of the great Reformers like a lion following the scent of truth
🐾 Apologetics & Evangelism – Defending the faith with the agility of a cat leaping against deception
🐾 Cultural Commentary & Church Decline – Addressing the slow creep of heresy, much like a cunning predator stalking its prey
Beyond his work at Calvinfelineism, Jean has dedicated himself to uncovering the history of Presbyterianism in Pyongyang, studying the unwavering faith of persecuted believers in Korea. Their steadfast endurance inspired him to remain bold in the face of modern apostasy. He is an outspoken critic of the prosperity gospel, hyper-charismatic movements, and theological liberalism, which he sees as theological strays leading the flock away from the truth.
Jean’s mission is clear: to equip the saints, defend the gospel, and glorify Christ with the precision of a panther and the courage of a lion. As the world grows darker, he remains steadfast in the doctrines of grace, knowing that the Lion of Judah reigns supreme.
Jean stand firmly on the doctrines of grace, upholding the absolute authority of Scripture and the sovereignty of God in all things. Jean faith is rooted in the historic Reformed tradition, shaped by the teachings of the Protestant Reformation and the confessions that faithfully articulate biblical truth.
Core Doctrine
1. The Holy Scriptures 📖
Jean believe that the Bible alone is the inspired, inerrant, and infallible Word of God (2 Timothy 3:16-17). It is the final authority in all matters of faith, doctrine, and life. No human tradition, personal revelation, or church authority can supersede the clear teaching of Scripture.
2. The Triune God 🔺
Jean believe in one true Triune God YAHWEH who eternally exists in three persons: Father, Son, and Holy Spirit (Matthew 28:19). Each person of the Trinity is fully God, equal in power, essence and glory, yet distinct.
3. The Sovereignty of God 🦁
Jean affirm that God is sovereign over all creation, history, and salvation. Nothing happens apart from His divine decree (Isaiah 46:9-10). He predestines all things according to His will, ensuring that His purpose is accomplished for His glory and the good of His people.
4. The Depravity of Man 🐾
All humans are totally depraved by nature, born in sin, and incapable of seeking God apart from divine grace (Romans 3:10-12). Sin has corrupted every aspect of human nature, leaving man spiritually dead and in desperate need of salvation.
5. Salvation by Grace Alone ✝️
Jean believe that salvation is by grace alone, through faith alone, in Christ alone (Ephesians 2:8-9). No amount of human effort, good works, or religious rituals can earn salvation. It is entirely a gift of God, given according to His sovereign mercy.
6. The Person and Work of Christ 🦁
Jean affirm that Jesus Christ, fully God and fully man, was born of a virgin, lived a sinless life, died as a substitutionary atonement for the sins of His people, and rose bodily from the grave (1 Corinthians 15:3-4). He ascended into heaven and will return to judge the living and the dead.
7. The Doctrine of Election 🐱
Jean affirm unconditional election, believing that before the foundation of the world, God sovereignly chose a people for Himself, not based on foreseen faith or works, but according to His good pleasure (Ephesians 1:4-5). Those whom He elects, He calls, justifies, and glorifies.
8. The Perseverance of the Saints 🐾
All who are truly saved will persevere in faith until the end (John 10:27-29). Though believers may stumble, they will never fully fall away, for God preserves His own.
9. The Church 🏛️
The true church is composed of all the elect, those whom God has called out of darkness into His marvelous light (1 Peter 2:9). The church exists to preach the gospel, administer the sacraments, and uphold sound doctrine.
10. The Second Coming of Christ ⏳
Jean believe in the visible, bodily return of Jesus Christ to judge the world and establish His eternal kingdom (Revelation 22:12). The wicked will be cast into eternal punishment, while the redeemed will reign with Christ forever.
Rejecting False Doctrines 🚫
Jean stand against all forms of theological error, including:
❌ The prosperity gospel – which distorts the true gospel for material gain
❌ Hyper-charismatic movements – which elevate personal experiences over biblical truth
❌ Hyper-grace theology – which denies the necessity of repentance and sanctification
❌ Hyper-Calvinism - which fail to see the commandment of Christ to evangelize the whole nations
❌ Ecumenical compromise – which blends Christianity with false religions and unbiblical traditions
11. Eschatology: Postmillennialism & Progressive Dispensationalism ⏳✨
Jean uphold a biblical eschatology that emphasizes both the victory of Christ’s kingdom on earth and the culmination of redemptive history in His return. While Jean primary stance aligns with Postmillennialism, he also acknowledge aspects of Progressive Dispensationalism that recognize God's unfolding redemptive plan through history.
Jean affirm that the gospel will gradually triumph over the world, leading to a golden age of widespread Christian influence before Christ’s return. This view holds that:
✅ The Great Commission will succeed in discipling all nations (Matthew 28:19)
✅ Christ is reigning now as King, expanding His kingdom through the church (Psalm 110:1)
✅ Over time, righteousness and peace will prevail as more people turn to Christ (Isaiah 2:2-4)
✅Christ’s second coming will occur after this millennial reign, bringing the final resurrection and judgment (1 Corinthians 15:24-28)
Postmillennialism encourages long-term kingdom work, fostering cultural engagement, theological reformation, and societal transformation under Christ’s lordship. Like a lion patiently expanding its territory, the church, through the power of the gospel, will subdue darkness and manifest Christ’s victory in history.
While Jean reject classical Dispensationalism’s rigid division between Israel and the Church, Jean recognize Progressive Dispensationalism as a biblical framework that:
✅ Sees continuity between the Old and New Covenants, with Christ as the fulfillment of Israel’s promises (Luke 24:27)
✅ Understands that Jesus is already reigning on David’s throne in heaven but will fully establish His rule on earth (Acts 2:30-36)
✅ Affirms a future restoration of Israel within the unified plan of redemption (Romans 11:25-26)
This perspective maintains the covenantal unity of God's people while acknowledging the progressive unfolding of His promises throughout history. Like a cat sharpening its claws in preparation for a greater hunt, God’s plan is advancing, bringing His kingdom to its ultimate fulfillment.
Whether through the gradual conquest of Postmillennialism or the progressive unfolding of God’s kingdom in history, Jean stand firm in the hope that:
🔹 Christ reigns now and His kingdom is advancing
🔹 The gospel will not fail, but transform the world
🔹 Christ’s return is certain, bringing the final resurrection and judgment
Jean are committed to advancing Christ’s kingdom, standing firm in biblical truth, and preparing for the glorious day when the Lion of Judah shall rule in fullness over all creation.
Jean remain unwavering in his commitment to sound doctrine, holding fast to the faith once delivered to the saints (Jude 1:3). Like lions defending their pride, we stand firm in the truth, knowing that the Lion of Judah reigns and His Word endures forever.
Though I may now live on this earth,
My spirit is stepping on Heaven's ground,
Where my Lord is and there is no tears,
There is found my hidden hope,
All those I miss when I think upon them,
Sometimes my heart is pounding
as I wait for it,
Where my Father Elohim embraces me in His wide stretched arms,
There is found my hidden hope.
Until I reach my Lord's Kingdom,
I will not stop my pilgrimage progress,
From this world to which is to come.
I realized I am a wretched sinner,
but Christ is a great Saviour,
No matter what trails come I am not afraid,
On this road I am with my Lord.
First and foremost, I am a citizen of the celestial city— So, too, is every Christian.
My evidence that I am saved does not lie in the fact that I preach,
or that I do this or that.
All my hope lies in this: that Jesus Christ came to save sinners.
I am a sinner,
I trust Him,
then He came to save me,
and I am saved.
Call me whatever. God chose me.
I was His enemy and had no desire for Him.
Left to myself, I would be bound for hell.
Let the will of man dogs bark, but my caravan is moving on.
Amen!
Eliyahu Ezra, is a former a minister and former layman laboring within the visible church, is now retired from formal ministry. His current focus is devoted to the authorship of a forthcoming theological work and the continuation of an online evangelistic ministry under the banner of Calvinfelineism.
The intent behind all of Eliyahu Ezra’s labors, whether in writing, teaching, or online discourse, is not self-aggrandizement, not the pursuit of personal fame, nor the gathering of earthly accolades. Rather, it is to equip the saints for the work of ministry (Ephesians 4:12), to build up the body of Christ in sound doctrine, and to proclaim the unsearchable riches of Christ to a lost and dying world by every available means, particularly through the avenues afforded by the internet.
It must be further noted, with no desire to conceal human frailty, that Eliyahu Ezra’s life is a testimony to the doctrine of total depravity. This is manifested even in his recreational pursuits, such as his enjoyment of various video games, particularly first-person shooters on the Steam platform — a vivid reminder that the remnants of sin cling even to those redeemed by grace.
Ultimately, the meaning of his existence is not grounded in his own identity, achievements, or failures, but solely in the sovereign reality of who God is, the matchless work of Jesus Christ, and the glory due unto Him alone. Soli Deo Gloria.
