Happy feast of the Transfiguration of our Lord!
We ourselves heard this voice from heaven while we were with him on the holy mountain. Moreover, we possess the prophetic message that is altogether reliable. You will do well to be attentive to it, as to a lamp shining in a dark place, until day dawns and the morning star rises in your hearts.
-- 2 Peter 1:16-19
