Read the _Thesauri_ of Cyril.[625] The work is dialectical, and
attacks the madness of Arius and Eunomius with vigorous and manifold
arguments. By logical methods he skilfully refutes their folly and
by combining and introducing evidence from Holy Writ he completely
exposes the unsoundness of their doctrine. He quotes the simple
evidence from Scripture, thus everywhere closing their insolent
mouths so that they are unable to answer. This work is the clearest
of all Cyril’s works, especially to those who are able to grasp the
significance of his logical methods.
