1) Where were the angels at the transfiguration?
2) Where was every man rewarded according to his works at the transfiguration?
I don't understand your logic here. What do angels being present and Christ rewards have do with his disciples seeing Christ in in His glorified state? "The Son of Man coming in his kingdom" was the event of his being transfigured into his glorified state. By the way, Jesus did not remain in that glorified state, but changed back to his normal human appearance after the cloud vanished and Moses and Elijah were gone.
Those thing that you mention above have to do with the angels appearing when Christ returns to end the age. As I showed you, Christ's reference to "the kingdom of God" had nothing to do with Christ's return to the earth, but was referring to those standing there who would not see death (Peter, John and James) seeing Christ in his glorified state. Your mind is still stuck on the event referring to Christ's return.
Also, I didn't tell you that information to debate it, but to reveal the truth to you. Christ's transformation into his glorified state is what he was referring to regarding Peter, John and James seeing the Son of Man coming in His glory (glorified state) and not his return to the earth.
The fact that you are asking questions about the events of Christ's return to the earth tell me that you are still interpreting what Christ said as referring to his return to the earth. Did you not read the scripture that I provided that used the same reference to "the kingdom of God" as referring to Jesus casting out demons by the Spirit of God?
Matthew 16:27-28 KJV
For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.
[28] Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
The two verses above are referring to two different events. In the first verse, Jesus is speaking in reference to when he returns to the earth to end the age. Then second verse is referring to Peter, John and James, getting a peek at Jesus glorified state when he returns in reference to the first verse. I say again, verse 28 was fulfilled when Jesus Peter, John and James saw Jesus in his glorified state.
Now you know when the SON OF MAN returned
The Son of Man has not returned yet. If he had, the world would have first had to experience all of the seals, trumpets and bowl judgments, which are the wrath of God. Jesus tells us that by the time the 6th bowl has been poured out, that he will have still not returned. Here is what Jesus interjects after the 6th bowl has been poured out:
"Look, I come like a thief! Blessed is the one who stays awake and remains clothed, so as not to go naked and be shamefully exposed.”
And if you are going to tell me that the seals, trumpets and bowl have already taken place, then you are deceived as so many others are. For they have no idea of the severity of the wrath that is soon to come upon this earth.
