Hubertus Gerardus Josephus Henricus Oosterhuis was a Dutch theologian and poet. He was mainly known for his contribution to Christian music and liturgy in the Dutch language, used in both Protestant and Roman Catholic churches, although a few songs have been censored in some dioceses. He was the author of over 60 books and at the time of over 700 hymns, songs, Psalms (often in an own interpretation), and prayers.
