Analytic doctrine is handmaid not mistress; ignorance of analytics breeds false spiritual proofs and obstinate heresy

So if to the analytic doctrine Aristotle hands down in the Organon we assign not a magisterium but only a ministry and service in seeking the truth of controversies — and if, with Jacopo Zabarella, who holds that the analytic species of logic, when applied to the disciplines, migrates into them, we still concede no metamorphosis of analytics inside theology — no one may fairly object that we are hunting analytic doctrine as mistress of knowing heavenly truth. It is only a handmaid; even when applied to theological matters it remains handmaid of the prince and Lady Theology.

But want of training in the analytics (ἀπαιδευσία τῶν ἀναλυτικῶν) in theology is nothing other than inability to tell apart, on the one hand, what needs proof from what is indemonstrable, and on the other, true proofs from false and pseudographic ones — and likewise theology's own proofs from alien and foreign ones. This is the most fertile mother of ψευδογραφήματα, false spiritual demonstrations, which breed ἄγνοιαν κατὰ διάθεσιν — the ignorance of a vicious affection in heretics and sectaries — altogether contrary to true knowledge or science of spiritual things. Just as that true knowledge is drawn from theology's true and proper principles, so by ignorance of a vicious affection we are seduced when we reason from false and foreign principles. Hence sectaries clutch their errors no less tenaciously, tooth and nail, than the orthodox defend the truth of their judgment, and think they certainly know what in fact they do not know. The same want of analytic training is also mother of many other errors in theology.
