Two of the more interesting verses are 99.13, which states Christ has a single hypostasis and 102.3, which states Christ is incomprehensible with respect to his hypostasis. The word ''hypostasis'' (hidden spiritual reality) was later adopted as part of the doctrine of the Trinity of Nicene Christianity. {{reli-book-stub}} Silvanus, Teachings of
