Christian belief in the Holy Spirit as the Third Person of the Trinity was not officially defined by the church until the fourth century. But centuries earlier, the Hebrew Scriptures and the New Testament were already describing the action and presence of God’s Spirit. In The Holy Spirit in the Bible, George Smiga unpacks key Scripture passages, exploring the activity of the Spirit at creation, within Israel, in the ministry of Jesus and the early church, and at the end of time. The role of the Holy Spirit in our personal and spiritual lives is also explored.
