TOGETHER FOR CHRIST
Behind CHRISTOlogisch are Josef, Alex and Karina. Together we want to strengthen Christians in faith, answer questions of faith and equip them to share the gospel.

Evangelist, apologist and author. Josef leads CHRISTOlogisch and oversees its content and direction.
Josef works full-time as an evangelist with the mission organization Bruderhand. He proclaims the gospel in churches, at public events and outdoors. As an apologist, author and theological adviser, he is responsible for CHRISTOlogisch's content direction. In talks, seminars and workshops, he teaches biblical doctrine, addresses questions of faith and equips Christians for conversations about faith and practical evangelism.

Counselling, evangelism and street outreach. Alex supports people and puts projects into practice.
Alex is a psychological counselor and is particularly involved in drug and addiction counseling and Christian addiction support. He is an open-air evangelist and street worker. He conducts apologetic debates, particularly in the Russian-speaking world. As project manager, he handles the practical implementation of our plans.

Photography, film and studio technology. Karina designs and produces the media for CHRISTOlogisch.
Karina is responsible for media production at CHRISTOlogisch. As a photographer, she combines visual design with technical implementation - from studio design through camera, lighting and sound to editing and postproduction.
JOSEF DRAŽIL
FOUNDER & DIRECTOR
THE FOUNDER & DIRECTOR OF CHRISTOLOGISCH
Welcome! Through CHRISTOlogisch, we want to help people get to know Jesus Christ, understand the Bible better and explore questions about Christian faith. We work toward this together: Karina, Alex and I.
Alongside leading CHRISTOlogisch, I work as an author and full-time evangelist with the mission organization Bruderhand. As a team, we want to explain faith understandably, take questions seriously and point to Jesus Christ.
One thing is particularly important to us: We do not have to earn God's grace. Salvation is his gift, which we receive through faith. This grace is also the foundation for growing in faith and serving others.
Our articles, learning sections and the online edition of the Axiom book are freely available. Creating them takes time and money. If our work helps you, please prayerfully consider supporting CHRISTOlogisch with an amount of your choice.
