About the Project

What is Christianity? is brought to you by the SL Brown Foundation (SLBF), which exists to provide resources in Christian thought and formation in the University of Wisconsin—Madison community and beyond. Our vision is renewed Christian presence in the pluralistic university where all are learning and serving to create a more virtuous world.
