Koinonia — koinōnia, fellowship — is communion with God and one another for the sake of the world. We exist to proclaim Christ, equip the church, and send the Gospel where it is needed most.
"Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you."
— Matthew 28:19–20 (ESV)

Nestled in the heart of Central Europe, the Slovak nation carries a story of faith written in fire — from the preaching of Jan Hus to the hidden churches of the Counter-Reformation, and the Bible that sustained a people for four centuries.

A Slavic People Called by God
The Slovaks are a West Slavic people whose homeland stretches across the Carpathian highlands, river valleys, and ancient trade routes of central Europe. Their story is inseparable from the spread of Christianity among the Slavs — from the mission of Cyril and Methodius in Great Moravia (9th century), who gave the Slavic peoples Scripture in their own tongue, to the Hussite movement that crossed the mountains into Slovak lands in the 15th century.
When Jan Hus — priest, philosopher, and reformer at Charles University in Prague — was condemned and burned at the stake on July 6, 1415, his death did not silence the fire he lit. Hussite armies and Czech refugees carried the Gospel and the Czech Bible into Slovakia. From strongholds in Zvolen and Košice, the Word spread among a people hungry for truth.
1415
Jan Hus Martyred at Constance
Despite a promise of safe conduct, Hus was tried for heresy and burned alive. His final words echoed through generations: faithfulness to Christ above earthly authority. July 6 remains a day of remembrance across Czech and Slovak Protestant communities.
1438–1453
Hussite Doctrine Reaches Slovakia
Czech noble Jan Jiskra controlled much of southern Slovakia. Hussite teaching and the Czech Bible took root among Slovaks, forging a spiritual bond between Czech and Slovak believers that would endure through persecution.
1520s
The Lutheran Reformation Arrives
Through German mining towns and merchant routes, Luther's message reached Slovakia. Slovaks embraced the Lutheran confession; Hungarians in the region often adopted Calvinism. By 1570, the Reformation enjoyed broad support across the entire territory.
1549 & 1559
Confessions of Faith
Five eastern cities published the Confessio Pentapolitana; seven mining towns presented the Confessio Montana — bold declarations that Slovak Protestants were not heretics but faithful witnesses to the Gospel.
1579–1613
The Kralice Bible
The Unity of the Brethren completed the first full Czech translation from Hebrew and Greek — the Bible of Kralice (Bible kralická). The 1613 edition became the Scripture of Slovak Protestants for nearly four hundred years.
1781
Edict of Toleration
After generations of suffering, Emperor Joseph II granted limited rights to Protestants. The hidden church could breathe again — but the memory of martyrs was never forgotten.
Faith Under Fire
Persecution & the Cost of Discipleship
The Slovak Protestant church did not grow in comfort. Under Habsburg rule and the Counter-Reformation, believers paid a terrible price to remain faithful to Jesus Christ.
900Protestant churches seized by force (1659–1681)
336Pastors condemned in Prešov alone (1674)
42Pastors sent to die as galley slaves
¾Of ethnic Slovaks were Protestant before persecution

In 1674, 284 Lutheran and 52 Reformed pastors were summoned to Prešburg (Bratislava). Two-thirds chose exile rather than deny their Lord. The remaining ninety-three were tortured and imprisoned; forty-two were condemned to row until death on Spanish galleys — a sentence reserved for the worst criminals.
Churches were confiscated at gunpoint. Families were forced into Roman Catholic baptism. Pastors preached in secret forests; believers gathered in barns and cellars, whispering Psalms they had memorized from the Kralice Bible.
Yet the church endured. Like the seed that falls into the ground and dies, persecution did not destroy the Slovak witness — it refined it. Koinonia Ministry International stands in that lineage: unashamed of the Gospel, committed to Scripture, and willing to serve wherever Christ sends us.
"They overcame him by the blood of the Lamb and by the word of their testimony; they did not love their lives so much as to shrink from death."
— Revelation 12:11 (NIV)

Our Projects
Preserving Scripture · Proclaiming Christ
From Bible translation to expository teaching and sacred art — we invest in work that outlasts a single generation.
Bible Kralická — Rebuilding for the Slovak People
The Bible kralická (Kralice Bible) was the first complete Czech translation from the original biblical languages, produced by the Unity of the Brethren between 1579 and 1594. For nearly four centuries, the Slovak people read and worshiped from this sacred text — the Scripture their pastors were imprisoned and martyred to preserve.
Koinonia Ministry International is working diligently to rebuild and rewrite this Bible for the people of Slovakia — honoring the faith of those who came before while preparing a faithful edition for a new generation. This work is prayerful, scholarly, and underway. It is coming soon.
