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".

The last half of the 20th century saw the establishment of the reputation of St Maximus the Confessor as the greatest of all Byzantine theologians, with a wholeness of vision that speaks directly to many of our concerns today.

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.

Are you an Orthodox Christian who wonders how to explain to your Baptist grandmother, your Buddhist neighbor, or the Jehovah’s Witness at your door how your faith differs from theirs? Or are you a member of another faith who is curious what Orthodoxy is all about? Look no further. In Orthodoxy and Heterodoxy, Fr. Andrew Stephen Damick covers the gamut of ancient heresies, modern Christian denominations, fringe groups, and major world religions, highlighting the main points of each faith.

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."
