Simply Christian by N. T. Wright is a thesis that argues the virtues of fundamental Christian doctrines and philosophy. The work explores various tenets and principles in Christianity, such as morality and the importance of cultivating a spiritual connection with God.

Although thematically Christian, Simply Christian also provides commentary on modern society and law. If taken out of the Christian context, Simply Christian could be considered an existentialist thesis in the same category as the works of Søren Kierkegaard, Jean-Paul Sartre, and Albert Camus.

Wright analyzes the tense dynamics of spirituality and the materialist world. While the main thesis is that the Christian ideology is the most sensible option in remedying the struggles in daily human existence, Wright's propositions can also be applied without the Christian context.

Simply Christian also has a socialist subtext. As it can be argued that Christianity—particularly the direct teachings of Jesus Christ—is fundamentally socialist (e.g. give to the poor, pacifism, share wealth, etc.), Wright devotes a significant portion of Simply Christian to criticism towards consumerism and capitalism's negative effects.
