What is "Advent" celebration all about?
I think it's a common misconception that "Advent" is just another word for "Christmas", and that celebrating one is the same as celebrating the other. Certainly as we celebrate this season we need to keep the focus wholly on Christ, and work against the culture of consumerism, or at the very least, against the watering down of the real reason for celebration. And that is a part of both of these words, but "Advent" takes on a further significance with perhaps a longer perspective of what the season means to us today.
In looking for a good definition of what Advent celebration is all about, I stumbled on an article which I think perfectly sums up its significance:
"Advent symbolizes the present situation of the church in these “last days” (Acts 2:17, Hebrews 1:2), as God’s people wait for the return of Christ in glory to consummate his eternal kingdom. The church is in a similar situation to Israel at the end of the Old Testament: in exile, waiting and hoping in prayerful expectation for the coming of the Messiah. Israel looked back to God’s past gracious actions on their behalf in leading them out of Egypt in the Exodus, and on this basis, they called for God once again to act for them. In the same way, the church, during Advent, looks back upon Christ’s coming in celebration while at the same time looking forward in eager anticipation to the coming of Christ’s kingdom when he returns for his people. In this light, the Advent hymn “O Come, O Come, Emmanuel” perfectly represents the church’s cry during the Advent season:
O come, O come, Emmanuel,
And ransom captive Israel,
That mourns in lonely exile here
Until the Son of God appears.
Emmanuel shall come to thee, O Israel.
While Israel would have sung the song in expectation of Christ’s first coming, the church now sings the song in commemoration of that first coming and in expectation of the second coming in the future."
