Using Bible passages as a guide, Haberer affirms and then challenges many closely held beliefs, making traditional distinctions between "conservative" and "liberal" Christians obsolete. It's Complicated harks back to Joseph Fletcher's twentieth-century classic Situation Ethics (Westminster John Knox Press) and gives readers a toolkit for Christian decision making in a variety of complex situations.

The book provides a framework for readers to reference when they're confronting moral dilemmas in their own lives, what Haberer calls "doing ethics by spreadsheet."
