I have already shown that there is NO SUCH THING as tongues (languages) of angels.
Let's look at the arguments around it.
I Corinthians 13
13
1 Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal.
2 And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
3 And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing.
Are tongues of angels fictional? Well, let's look at the context.
Are tongues of men fictional? No.
Is there such a thing as sounding brass or tinkling cymbals? If there weren't, how would they know what he was talking about.
Is prophecy a real thing? Yes it is.
Are mysteries, knowledge, and faith fictional? No.
Are mountains just imaginary? Are they fictional? No.
Is it impossible to give all one has to feed the poor? No.
Is it impossible to give one's body to be burned? No, and there were Christians Nero burned as 'human candles' within decades of this.
Even while Paul was Paradise, he understood what was being said, but was forbidden to disclose it. And every time an angel spoke in Scripture it was either in Hebrew or Aramaic.
(But what about quotes from angels in Greek? Do you think the angel spoke to Cornelius in Greek, and do you have any quotes from angels that are in Aramaic from the Bible.)
And "tongues of men" simply means human languages.
