There is only one source, one spring of Joy — for both the pagan and the Christian — and it is Christ. And if the source of Joy be attributed to any other such thing, it is idolatry against the Most High. One One is found Good, only One is the essence of Beauty, and from Him does all other goodness and beauty flow. Loveliness is intrinsic to One, and One alone.
If this is true, then idolatry really is an abominable thing, exchanging the glory of the immortal God for images that resemble mortal man (Romans 1).
Why then do we have the proclivity to remove glory from the only Glorious One, and bestow it upon mortal man, who is but a reflection of divine perfection? It is pervasive throughout the hearts and minds of believers and unbelievers alike. We cease to give glory to our Creator, barely acknowledging his existence, and instead, we glorify the Creature.
We worship the beauty of this world, while denying the beauty of its Source. We seek to become like God through sinful pride and arrogance; He seeks to make us like himself through humble meekness and love. Oh, the depth of the riches of this great mystery!
