Sexual & Gender Identity Institute

The mission of the Sexual & Gender Identity Institute is, from a Christian worldview, to further our understanding of sexual and gender identity, and the intersection of these identities with religious identity, and to be a resource to the church and to the broader culture.  We do this through research, training, and consultation.

The mission of SGI is consistent with the Wheaton College Community Covenant.
