This book explores the construction of Christian identity in fourth and fifth centuries through inventing, fabricating and sharpening binary oppositions. Such oppositions, for example Christians - pagans; truth - falsehood; the one true god - the multitude of demons; the right religion - superstition, served to create and reinforce the Christian self-identity. The author examines how the Christian argumentation against pagans was intertwined with self-perception and self-affirmation.
