That is a very interesting assessment as many attempt to, and I could list quite a number of passages which are used by Trinitarians, especially on forums, starting for example with Genesis 1.
Hi Trevor —
Oh, I know. On my course, the contrary argument was if the doctrine was revealed in the OT, then the Jews would acknowledge it. As I said above, we post-Incarnation Christians can see traces, in the light of Christ, but we see a lot more in that light.
Again this is one of the popular portions used by Trinitarians on forums. I am not permitted to discuss the subject here, and as mentioned in a previous post, I have now started a thread "The Yahweh Name" in the Controversial forum and I am having difficulty answering all the participants and their concepts. I will add my view here that the three "men" who appeared to Abraham were Angels, but willing to discuss this in the Yahweh Name thread.
I study Comparative Religion (a 'Traditionalist' in the sense of the Sophia Perennis, writers such as Guénon and Schuon, Lings and Pallis, if you know those names), Christian Platonism and Hermeticism. I use Plotinus' arguments from 'The Enneads' to explain the One-ness and Three-ness of God – but you can't prove the Trinity from Plotinus! I have argued in certain circles that Three is a 'mystical' number because the cosmos is 'Trinity-shaped'! But that is a conviction, it's not a proof ... and yes, the most I can assert were the three men at Mamre were angels, to say they were the Trinity is a gross overstatement. (I did like the scene in the movie where all three were played by Peter O'Toole. He might have piercing blue eyes, but he was no angel, LOL)
Perhaps this reflects what we experience on the forums, that many Protestants claim that the Trinity was obviously taught in the OT, partially hidden in such passages as Genesis 1 and Genesis 18, and that the OT faithful should have understood this.
Personally I think that's over-stepping the case. It's not the Catholic position and nor is it, I believe, the Orthodox. I could be wrong there. On my degree course, which was
very Traditional Catholic, the suggestion was not acceptable.
Protestants quite rightly chastise Catholics for not reading enough Scripture, but I would then say that the Jews have read and discussed Scripture way more than Protestants! If the Trinity was revealed there, they'd have found it.
Regards.
