Some people refer to the Holy Spirit as the “neglected” member of the Trinity. Certainly, all three persons in the Godhead have been given short shrift at different times and among different groups in the church. But in their history, Protestants can find many who explored the nature and work of the Spirit, though perhaps none more thoroughly than the seventeenth-century Reformed theologian John Owen (1616–1683).
In his later years, Owen penned several treatises beginning in 1674 that were later drawn together in one volume under the title Pneumatologia, or Pneumatology. Some have called this book the best work on the Holy Spirit in the history of the church.
