The Transfiguration of Jesus - This experience of Jesus is sandwiched between the mental sufferings of Jesus and the physical. The Transfiguration experience is the external manifestation of the inner transformation that accompanied both His mental and physical pains.
There was peace - joy, inner freedom that went hand in hand with the pain. The Transfiguration is the external overflow as if it were of His inner being.
Fr. Siri Oscar Abayaratne.
