HA! THAT's not old-fashioned. Puritanical, maybe, but not old-fashioned.
Give a little thought and consideration to just how much of history's great art features Biblical themes; how much of it graces centuries-old cathedrals and churches.
A separation of church and entertainment? That there ever was some wedge driven between the two is the major reason behind the dominance of secular themes in modern art and entertainment. Where are the "Michelangelo's" of our day? Name the "Ode to Joy" of our time. Who is the "Handel" of the 21st Century, and what is the title of his "Messiah"?
The de facto attitude among many Christians seems to be that art and entertainment are destined to be ruled by secularists; that "Christian Music", or "Christian Books" are doomed to always be some sort of minority splinter off of the whole; that no Christian might ever again produce a work to rival the Pieta; that no Christian might ever produce another work to rival "Messiah"; that no Christian might ever compose music so powerful as that of J. S. Bach, or create a painting as majestic as the ceiling of the Sistine Chapel.
To mentally capitulate artistic superiority to secular society over some Puritanical notion that Christians ought not engage in such frivolities as art... NO!
No. The Greatest Story is OUR SAVIOR'S story. The Greatest Books tell of him. The Greatest Songs, are HIS songs; all about Him. The Greatest Music is that directed toward Him. The Greatest Paintings are all about Him; His life, His work, His heritage, His Truth, and His Coming again. The Greatest Sculpture likewise. And so ought it be for the Greatest Films, the Greatest Plays, the Greatest of all artistic works.
What excuse should we give that those Christians blessed with inordinate artistic talent should bury it in the ground and not see it multiplied? Let it never be, but let their talents be fully and enthusiastically invested for the glory of God and for sake of His Kingdom, that they may bring a return that the Father may ultimately note and for which He may give His commendation, "Well done, thou good and faithful servant."
Michaelangelo, Bach and Dante are not cheap entertainment, like Hollywood trashy "entertainment vehicles", Christian rock, and flea market velvet Jesus. To compare those is laughable!
