Definition of the Transfiguration
Jesus, whose glory was veiled in flesh, became unveiled to
those 3 disciples and they beheld his glory. The Greek word
Metamorphao means to transform or transfigure. Both Matthew
and Mark use the same word metamorphao in Matt 17:2 and Mark
9:2). Luke did not mention the word transfiguration but he
said that the appearance of his face changed (Luke 9:29).
Matthew said that his face shined as the sun (Matt 17:2),
and Mark said that his clothing became as light, exceeding
white as snow (Mark 9:3). What had actually happened was
that Jesus, whose glory was veiled in flesh, became unveiled
to the 3 disciples and they beheld his glory, the same glory
that will be seen when he returns to set up his kingdom
which will never pass away.
