Justin and Prophecy

In chapters 83-86 Justin continues to interpret the OT Christologically to justify the Christian faith. Whilst I sympathise with his approach, it is rather disconcerting to observe that he seems unaware that this is what he is doing. Hence, not all the arguments that he uses to defend the objectivity of his position (e.g. the superiority of the LXX over the Hebrew text of the OT) are convincing.
