Church choir soloists will likely never be famous singers, never be on a notable stage, never sing with the symphony. Church choirs will likely never be heard by anyone beyond the church, except for maybe friends and family.
Church choirs, though, share more than the greatest operatic and orchestral performances. They share faith through music, and they share faith especially and by design within the context of community.
The beauty church choirs share, objectively, will probably never be at the same level as top performers. But beauty is not objective ~ beauty is found elsewhere. And from the voices of the choir composed of friends whose lives we share and participate in, to the ears of the beholders, church choirs open up compositions of faith in such a way as to bring to a community the promise of new life.
