One great thing about being Catholic is there are a whole lot of cool words that you get to use. One of my favorites is doxology. The word doxology alone just sounds really neat. But doxology is itself also something pretty awesome when you think about it. After all, doxology is a hymn of praise usually directed toward the Holy Trinity and usually affirming the infinite quality of God.
Catholics will recognize a few standard doxologies like the "Glory be" and the "Through him, with him, and in him, in the unity of the Holy Spirit, all glory and honor is yours, almighty Father, for ever and ever." that the priest prays before the Great Amen of the Eucharistic Prayer during Mass.
But why do I think that doxologies are so great? As we learn from the Catechism of the Catholic Church, paragraph 45, "Man is made to live in communion with God in whom he finds happiness". Heaven is where we will be in communion with God fully. Heaven then, is what man was made for it would seem.
In the Bible we get several "glimpses" of Heaven. In most of these glimpses we see that the angles and saints are engaged in hymns of praise towards God. This is why I think that doxology is more than a really cool word that Catholics get to use. It is kind of like a rehearsal for Heaven, or an audition even. Now that is pretty cool if you ask me.
