Pet peeve: Hymnals that only print bowdlerized versions of the lyrics. 

Print alternate words in italics for those who find the original versions objectionable for whatever reason, but stop forcing these watered-down, downright "clunky" bits of inferior verbiage on the rest of us. 

Human thought, including human religious thought, has evolved and unfolded over time, and "fixing" the lyrics not only reduces what is often quite good poetry to the level of insipid, PC-driven mush, it also robs us all of a clear sense of our heritage, in all its nuanced magnificence.
