/summa/TP/TPII/TP_Q45:
We now consider Christ's transfiguration; and here there are four points of inquiry:
(1) Whether it was fitting that Christ should be transfigured?
(2) Whether the clarity of the transfiguration was the clarity of glory?
(3) Of the witnesses of the transfiguration;
(4) Of the testimony of the Father's voice.
