Don't ignore the little phrases like "verily, verily", they hold GREAT meaning.
In every case in the Gospels where this phrase is used it is an elaboration and/or application of the verses just prior.
But I see you left those verses out.
Here is the whole context of Matt.16:
27 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.
Mark 8:38-9:1
8:38 Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh in the glory of his Father with the holy angels.
9:1 And he said unto them, Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.
Luke 9:26-27
26 For whosoever shall be ashamed of me and of my words, of him shall the Son of man be ashamed, when he shall come in his own glory, and in his Father's, and of the holy angels.
27 But I tell you of a truth, there be some standing here, which shall not taste of death, till they see the kingdom of God. [/COLOR]
I can see why you left these explanatory verses out; they do not fit your explanation that this prophecy refers to the Transfiguration.
Consider carefully the words underlined. This coming is much more than that Transfiguration. It has the following elements:
1. Christ will be ashamed of the ones who were ashamed of Him.
Did that happen at the Transfiguration?
2. He will come in the glory of the Father and of the angels.
Did that happen at the Transfiguration?
3. He shall reward every man according to his work.
Did that happen at the Transfiguration?
No, no, and no.
Look, nobody saw Jesus come in his glory with his angels in 70 A.D. either, but Peter, James, and John saw Jesus in HIS GLORY, that is plainly said.
Luk 9:30 And, behold, there talked with him two men, which were Moses and Elias:
31 Who appeared in glory, and spake of his decease which he should accomplish at Jerusalem.
32 But Peter and they that were with him were heavy with sleep: and when they were awake,
they saw his glory, and the two men that stood with him.
And let's look at the verses you posted;
Mat 16:27 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.
Mar 8:38 Whosoever therefore shall be ashamed of me and of my words in this adulterous and sinful generation; of him also shall the Son of man be ashamed, when he cometh
in the glory of his Father with the holy angels.
9:1 And he said unto them, Verily I say unto you, That there be some of them that stand here, which shall not taste of death, till they have seen the kingdom of God come with power.
Luk 9:26 For whosoever shall be ashamed of me and of my words, of him shall the Son of man be ashamed, when he shall come
in his own glory, and in his Father's, and of the holy angels.
27 But I tell you of a truth, there be some standing here, which shall not taste of death, till they see the kingdom of God.
I am sure you will not admit of this, but it is very possible that in each of these three examples, the first verse IS speaking of when Jesus comes to judge the world, but the second verse is speaking of the transfiguration. You know as well as I do that scripture is often written this way, it can jump from one time period to another from verse to verse, or even at a comma!
It is similar to the day of Pentacost when Peter said scripture was fulfilled;
Acts 2:16 But this is that which was spoken by the prophet Joel;
17 And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:
18 And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy:
19 And I will shew wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapour of smoke:
20 The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come:
21 And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
On the day of Pentacost, when the disciples had flames above their heads and spoke with tongues, Peter said it was a fulfillment of scripture in Joel.
But not EVERYTHING Joel predicted happened. There was no blood, or smoke, the sun was not darkened, nor did the moon turn the color of blood. Yet Peter said this was a fulfillment of Joel. And it was, though it was only a "partial" fulfillment.
I propose it is the same when Jesus made these three statements in Matthew, Mark, and Luke. The three disciples did not see Jesus come with his angels and judge the earth, but they most certainly saw Jesus come in power and glory. The rest will be fulfilled in the future, just as the rest of Joel will be fulfilled in the future.
