ADVENT - real ?

The Catholic Church has invited us to keep Advent in our memory. Advent is the time before Jesus Christ was born. Many many years people have been crying and waiting for a Redeemer (some until today). Finally HE came; the Arrival is a FACT; it means ADVENT is over. Now a day there is no more a real ADVENT. It's for Christians very important to know the difference: There is a time before Jesus Christ was born and there is a time after Jesus Christ was born. There is a time of pregnancy and there is a time after-birth. If we sing: "oh come oh come Emmanuel", we unite us with people long ago; we participate with their hope and expectation; we celebrate a FACT, already happend.
But for us it's strange; a time without Jesus Christ is nearly unthinkable. Is it possible for us to come together next Sunday to tell everybody (maybe also on TV): sorry people, there is no redeemer born yet; but we feel a redeemer is most needed - so we held up our arms and cry as loud as possible " oh come oh come Emmanuel" ?  pls come asap...
The Church would excommunicate us. Don't forget: it's the message of the Church: the Redeemer is born (cf. our celebration of Christmas). The Church teaches us: the birth of Jesus Christ is a real FACT, not an illusion, not a fiction. And the Church also says: it's clever to accept the reality. The solution is "hear and see". A day-dreamer is not fit for our world-situation. If you wait for the Redeemer you are not a realist; you are a blind-walker.

Problem Nr 1:
HOW do we express our conviction: the real Redeemer already came ? Since 2000 years
every day HE offers his life-style, his message, his presence - and more - HE has given his presence in different ways and even in greater understanding than ever. His Arrival has started; HE is known as born, as Prophet, as Healer, as Unifyer, as crucified and as risen into the fullness of Life.  HOW WE EXPRESS THIS FACT ???

Problem Nr 2:
WHY the Church is undecided in the liturgical language - causing a lot of trouble and uncertainty. How many times Christians pray: "come Lord Jesus come" ? Such a prayer is denying the reality, is refusing to accept his Arrival as a FACT.

If HE wouldn't have come, we would know nothing about HIM - now as HE came - 
at least be real.
