BAPTISM to legitimatize Jesus (13.01.13)

After the wise men from the east has given witness (Mt 2.1-12):
The NEW Shepherd of the "people of God" is now JESUS (and not the Temple)
+ to HIM we pay homage
+ to HIM we give the gifts
NOW it's GOD himself who give witness (Lk 3.15-16 + 21-22)::
+ the heaven opens for HIM
+ the Holy Spirit descends on HIM
+ the heavenly Voice declares about HIM: HE is the "Son of God"
                                                                 HE receives the favour of God.

Every listener gets the message: that this JvN (once died on the cross)
is "in reality" the NEW Shepherd of all; the promised MESSIAS.
Once the human wisdom and the voice of God have been raesons to hear and to follow Jesus of Nazareth.
But today in 2013 how we legitimatize the call of the Church to hear Jesus
and to follow HIM ? By our drop-drop baptism ? by our take-away-confirmation ?
"Heaven opens" means in a new translation: "the door into the fulness of Life is now open" - but how we show this at the Baptism-Celebration ?
