This is a wonderful article from Glory to God for All Things – one of my favorite, thought-provoking, Eastern Orthodox blogs.
Here's a caution:
Not all paintings are icons. Not all music is iconic. Not every voice is raised in union with the heavenly hosts. To write a true icon is a great and holy thing. To sing in a manner that reveals heaven and unites us with the heavenly hosts is a great thing indeed. We were created to sing in just such a manner.
Just keep this in mind, especially as we all move into the season of Lent. Thanks, Fr. Stephen, for these great thoughts.
