Nonsense
Your claiming God wants people to pray to some high angel and the angel will answer their prayers.
Its almost blasphemy
Not at all, the concept of The Divine Logos being the agent and intermediacy of THE god is well established in the Targums. Later Jewish tradition may have abandoned it though.
Where many Trinitarian translations get a little dishonest is in adding the "me" to "Ask me". It just says "Ask in my name". So you pray to God for something, "in Jesus's name" (Whatever that means exactly being up to debate), and Jesus will be sent to do it.
World English Bible
If you will ask anything in my name, I will do it.
Young's Literal Translation
if ye ask anything in my name I will do it.
See there? No "Me". Nothing about praying to Jesus himself. The "me" is added by Trinitarians and isn't in the text. There's absolutely no reason to definitively add the "me" there unless you're trying to force a Trinitarian interpretation, gramatically speaking. So thus, the verse only involves praying to Jesus through deliberate dishonesty by certain Translators pushing a Trinitarian agenda who add the "me" there which completely changes the context from what the text actually says.
Not exactly the first time Trinitarian translators have read more into the text than what's there for the sake of doctrine.
