Secrets revealed? The Gospel reading is the Finding in the Temple, in which Jesus tarries around in the Temple a few days after Mary and Joseph left Jerusalem to go back home to Nazareth following the Passover celebration. It is also the last thing we read about him as a child. The next event in his life that we will read about is his baptism by John the Baptist.
All of this leaves room for much speculation. We can, of course, speculate and surmise from what we find in other sources and tradition.
