And their grasp of those doctrines is so meagre that no definite creed can be attributed to them. If you were to ask one of their priests about their belief regarding the Messiah, and then ask his own father and mother, the three of them would give you three different answers—each one unlike the others.

One of the critical scholars remarked:

“There is no assertion put forward by any group possessed of reason which, when examined, fails to yield some intelligible meaning—even if it is false—except the doctrine of the Christians. However long you reflect on it, you will not be able to conceive any intelligible reality for it. At best, they merely preserve the ‘Creed’ and the like; yet when called upon to explain it, each of them offers an interpretation that declares the others unbelievers. So the Yaʿqūbiyya (Jacobites), the Malkāniyya (Melkites), and the Nastūriyya (Nestorians) anathematize one another over their divergence on the very roots of monotheism and prophethood. Their discourse on these two foundations is among the most corrupt and internally contradictory of statements, as has been shown elsewhere.”
