"By Whatever Name We Call You"

During a church service a few weeks ago, I was introduced to a hymn in the UCC's New Century Hymnal titled "By Whatever Name We Call You". I liked the words in verse 2:

In whatever name we worship, Mystery Divine,
You are only dimly known through ritual and creed.
Though we try to capture you in symbol or in sign,
Only as we let you be, can longing hearts be freed.
