Fred Sanders is a theologian who tried to specialize in the doctrine of the Trinity, but found that everything in Christian life and thought is connected to the triune God. As a result, he studies, teaches, and writes across the full range of Christian doctrines. Since 1999, Fred has taught in the Torrey Honors College, an undergraduate program in the great books, at Biola University. Fred studied art (drawing and printmaking) in college, earned an MDiv at Asbury Theological Seminary, and a PhD from the Graduate Theological Union in Berkeley, CA. He and his wife Susan (who have been friends since they met at age 11) are members of Grace Evangelical Free Church in La Mirada, CA. They have two adult children. Fred has written several books and articles; his most important books are The Deep Things of God: How the Trinity Changes Everything (Crossway, 2010); The Triune God (Zondervan, 2016); and Fountain of Salvation: Trinity and Soteriology (Eerdmans, 2021). He blogs copiously at scriptoriumdaily.com, and maintains an active presence on Twitter.
