vi. from book iii.

But as they have been refuted in all their allegations, and are thus at a loss what to say, they try to take refuge in their martyrs. For they say that they have many martyrs, and that this is a sure proof of the power of their so-called prophetic spirit. But this allegation, as it seems, carries not a whit more truth with it than the others. For indeed some of the other heresies have also a great multitude of martyrs; but yet certainly we shall not on that account agree with them, neither shall we acknowledge that they have truth in them. And those first heretics, who from the heresy of Marcion are called Marcionites, allege that they have a great multitude of martyrs for Christ. But yet they do not confess Christ Himself according to truth.
