I do not mean that 'marginal glosses have frequently found their way into the text':--that points to a wholly improbable account of the matter.

I mean, that expressions which seemed to countenance heretical notions, or at least which had been made a bad use of by evil men, were deliberately falsified.

But I must not further anticipate the substance of the next chapter.
The men who first systematically depraved the text of Scripture, were as we now must know the heresiarchs Basilides (fl.

134), Valentinus (fl.
140), and Marcion (fl.

150): three names which Origen is observed almost invariably to enumerate together.
