It's near to impossible to believe something like that and still be a Catholic. The revelation to us of the second Person as Logos assures us that beauty, subtlety, economy, order, and reason are all godly attributes. Hence their absolute qualities. When God created the world and saw that it was good, he wasn't expressing some arbitrary, idiosyncratic opinion.
The unreflective acceptance and canting repetition of such sentiments as "beauty is in the eye of the beholder" is an assertion of radical relativism. It's a reflection of the fallen, alienated world in which we live and is about as far as you can get from the redemption, in which all things are made right in Christ.
Someone recently said that Mahony's Cathedral in LA will be old fashioned in the near future. The ceramic "tree of life" chalice and ciborium used by my parish priest is already hopelessly outdated as well. Typical 70s hippy stuff.
But traditional beauty will and always has lasted for centuries and people know that in their hearts. Notre Dame vs. Mahony's Cathedral.
As a corrollary, the Church abhors the concept of "ars pro gratia artis" which detaches art from Beauty, Truth, Goodness, and Holiness--the ONLY qualities which make art 'art'...
