Common language. Common people. Extraordinary message. That's what Koiné was in the 4th and 5th century in then Macedonia, the common language of the people. It's a Greek term, and was the language the New Testament was written in. Today, Koiné is again a voice for the common people, and again with extraordinary message. Koiné - the church band, is a contemporary Christian band, bringing a new vibrant sound and feel to traditional Lutheran and Christian songs. Founded on the banks the Milwaukee River on Milwaukee's near North Side, Koiné brings a new and needed voice to the arena of Christian music.
