About Codex: Unreached Languages
Codex is a catalog of unreached language groups that includes a description, photographs, and prayer points. Those groups that have been verified by Missionary are part of the daily prayer rotation. Pray for the unreached, from Tajikistan to Papua New Guinea to the Amazon.
Millions of people still cannot hear the gospel in the language of their heart. And yet, those who would bring the gospel have no knowledge of who those people are. Enter Codex.
Codex is a digital repository of unreached language groups. It brings the knowledge of the unreached to the saints who can reach them.
Each day, the app gives you one language group to pray for: who they are, where they live, what they believe, and how to pray for them. Profiles verified by Missionary’s team carry the stories, photographs, and prayer points.
ONE GROUP A DAY
Build a gentle daily rhythm. Join others praying with the app and lift the same group up on the same day. Enable a daily reminder at the time that works for you, and start a streak as you pray.
HUNDREDS OF LANGUAGE GROUPS
Beyond the verified profiles, explore hundreds of unreached language groups drawn from public missions data: groups with no gospel, no disciples, and no church in their own language. Search by language or country, filter to frontier groups, or browse by Bible translation status.
SEE THE TASK ON A MAP
A world map plots every group in the guide, from the Caucasus to the Sahel to the islands of Southeast Asia. Every dot is a people waiting to hear.
WHY LANGUAGE?
Churches often think in terms of geography or people groups, but the Bible calls us to reach every tongue. The app explains why we count the unreached by language: language marks exactly where a person can, and cannot, hear and read the gospel.
FROM YOUR CHURCH TO EVERY LANGUAGE
Codex is built by Missionary—helping local churches send missionaries to peoples who have never heard of Christ. Praying through this guide is the first step.
“I make it my ambition to preach the gospel, not where Christ has already been named.” — Romans 15:20
