"I establish the fact that this prophecy of Isaiah speaks of our Christ and not Hezekiah, as you claim, will you not be obliged to doubt your teachers who dare to assert that the translation [of the Scriptures found in the Septuagint] made by your seventy elders at the court of the Egyptian King Ptolemy is inaccurate in some places? For, whenever there arises in the Scriptures an evident contradiction of their silly and conceited doctrine, your teachers boldly affirm that it was not so written in the original text. And they conspire to distort other statements, harmonizing them with human actions and claiming that they have been spoken not of this our Jesus Christ, but of him of whom they attempt to interpret them. For instance, they taught you that the quotation under discussion is to be interpreted as referring to Hezekiah, a statement which, as I promised, I will prove to be a lie. Under pressure, they are forced to agree that some of the passages we cited -- passages already quoted to you which clearly prove that Christ was to suffer, to be worshipped, and to be called God -- were indeed spoken of Christ. They boldly deny that He whom we worship is the Christ, yet they admit that a Messiah will come to suffer and rule and be worshipped. This opinion, too, I will prove to be absurd and senseless. But, as you have compelled me to first answer what you have said in ridicule, I will do so, and then I will pass on to the proofs of the other subjects." Justin Martyr's
