I've worked in the church for over forty years and have gone through two mergers and at least a half-dozen hymnal changes (I'm a musician). I will NEVER forget looking through comment cards in the 70s. My favorite - complaining about the new wording of the Lord's Prayer: "Why can't we say it the way the Lord said it?" - with NO CLUE that the Lord wasn't speaking American English while on earth!!
Change is difficult; it is humanly impossible to anticipate all problems or to please everyone. I've noticed improvements since the changeover, obviously responding (quickly!) to issues that have arisen. Thank you to everyone behind the scenes! Your efforts are well worth it!
