“”Danielle Elizabeth Tumminio is a priest, theologian, a certified life coach and spinning instructor, and the author of ‘God and Harry Potter at Yale: Teaching Faith and Fantasy Fiction in an Ivy League Classroom’...””
I do not know anything about her background other than what was mentioned, that she is an Episcopal Priest.
I do know she wrote a fair and even handed article...which is true and stands on its own even if there are other areas that we do not agree on...as I am sure there are.
