Saint Gregory of Nazianzus, also known as Gregory the Theologian, lived an illustrious life as an orator, poet, priest, and bishop. Until his death, he wrote scores of letters to friends and colleagues, clergy members and philosophers, teachers of rhetoric and literature, and high-ranking officials at the provincial and imperial levels, many of which are preserved in his self-designed letter collection. Here, for the first time in English, Bradley K. Storin has translated the complete collection, offering readers a fresh view on Gregory’s life, social and cultural engagement, leadership in the church, and literary talents. Accompanying the translation are an introduction, a prosopography, and annotations that situate Gregory’s letters in their biographical, literary, and historical contexts. This translation is an essential resource for scholars and students of late antiquity and early Christianity.

ナジアンゾスのグレゴリオスによる書簡集は、単なる宗教文書を超えた、魂の叫びと高度な修辞学が融合した文学的傑作です。神学者としての厳格な仮面の裏にある、友人への情愛や孤独、そして激動の時代を生きる一人の知識人の生々しい葛藤が、現代の読者の心に強烈に訴えかけます。 本書の魅力は、言葉を「信仰の武器」かつ「芸術」として操る彼の比類なき文才にあります。帝国高官から哲学者まで、多岐にわたる相手に宛てた言葉の数々は、古代末期の熱狂的な社会像を鮮やかに描き出します。知性と情熱が交錯するこの書簡集は、読者を千数百年前の深遠な精神世界へと誘う、時空を超えた招待状なのです。
