St. Gregory of Nyssa (AD 335 - 395), the great theologian and bishop of Nyssa, turned his considerable skill to finishing the work that his brother St. Basil the Great had started on the creation of the world (the Hexaemeron). The result is this book, which examines how humans are formed as a "mean between the divine and brute beasts". 

By any standard, this is a classic of Christian theology. Composed by St. Athanasius in the fourth century, it expounds with simplicity the theological vision defended at the councils of Nicaea and Constantinople: that the Son of God himself became "fully human, so that we might become god."

In this classic book, John of Damascus laboured to form one complete, clear, and brief theological work that would summarize all Christian doctrine that had been passed down and agreed upon. The following was said of the book: The result was an inexhaustible storehouse of tradition in which nothing is to be found that has not been either approved by the ecumenical synods or by the established leaders of the Church. 

The Life of Saint Macrina is a significant work of early Christian literature written by Bishop Gregory of Nyssa. In the form of a letter to the monk Olympus, Gregory describes the life and influence of his sister Macrina. Macrina – also known as "Macrina the Younger" – had helped to establish a monastery and convent in Pontus (in modern-day Turkey) in the fourth century AD. The story centres on Gregory’s final visit to Macrina and is written as testimony to her piety, sanctity, and holy influence. 

The audiobook version of this book on an approach to the world and life within it stems from the liturgical experience of the Orthodox Church. The author understands issues such as secularism and Christian culture from the perspective of the unbroken experience of the Church, as revealed and communicated in her worship, in her liturgy—the sacrament of the world, the sacrament of the Kingdom.
