Common language is an important part of organizational culture, but did you know that it’s also a powerful component of Christianity?

If you’re a newer believer, it might feel like people in your church or Bible study are speaking a different language. That’s why we’ve created a go-to resource that will serve as your translation manual.

Read on to learn 30 biblical definitions every believer needs to know.

  1. Apostle: A title referencing any of Jesus’ 12 disciples after the resurrection of Christ, but sometimes references other Christ followers with whom Jesus revealed Himself physically after the resurrection, such as Paul.

  1. Communion: One of the two ordinances of the church, communion is an experiential symbol of the death of Jesus Christ for sinners. Using the elements of the bread, which represents Jesus’ body that was crushed on the cross, and the wine or juice, which represents Jesus’ blood that was spilled on the cross, the church remembers together the great sacrifice of Jesus and uses communion as a way to help wait for His return.

  1. Heaven and Hell: When individuals die they either go to heaven or hell. Heaven is the destination for those who trust in Jesus and are saved where they will be given glorified bodies and will enjoy being with God forever in a sinless, painless, and perfect place.
