  • Calvin Howe Professor of Finance

I want my students to see how the Bible speaks to their situation, how the Bible speaks to economics, how the Bible speaks to finance, and how the Bible speaks to business ethics. Part of the reason we feel that it’s important in the School of Business is because we see business as a high and holy calling. We see business as a place where our graduates can go into the world and make a difference, not only by being excellent in terms of business but by being a light in a place that’s often very dark, being a voice for the kingdom of God, and being an example to others of how life should be lived to its fullest.
