This is a small volume comprised of Loof’s lectures on Nestorius and his position in the history of Christian Doctrine. After 1500 years stigmatized as a heretic, a book written by Nestorius was discovered in 1895, known as the Bazaar of Heracleides , written towards the end of his life, in which he explicitly denies the heresy for which he was condemned, instead, affirming of Christ the same one is twofold - an expression similar to the formulation of the Council of Chalcedon. This recent discovery is included in Loofs discussion of Nestorius.
