Haka Kekäläinen loves God. He also, like a lot of people in Finland, loves heavy metal. So when he became a Lutheran pastor, Haka thought, “Why not have a metal mass?” His church conducts regular service, but with hymns set to heavy metal. While his approach might seem unorthodox, Haka is packing the pews with his take on mass. Say amen and get ready to slay.
