The Introduction familiarizes the reader with Athanasius's writings and the historical context of his theology. The reader will engage with the Athanasian language and thought that shaped the Christian understanding of the Trinity. The reader also takes a journey through Athanasius's understanding of the human person, created in the image of God and living the life of renewal. The Introduction aims to guide the reader to a Christian theologian who had the courage to oppose emperors and bishops, and to endure exiles and other threats because of his unwavering theological convictions.
