This thing reads more monotonally than much of anything I've read in awhile; that is, it sounds like the sort of Latin stuff the priests would throw at us in my Catholic youth, at the end of which we would obediently chant together (as the poet does here as well) "Amen".
That is not to say that it is boring, but that it is sermon-like, as Richard suggests. As well, it teaches me all that I probably need to know about Yom Kippur, so, again, it is sermon-like in that fashion as well.
Even so, there is much to like about the phrasing, although I have a few issues as well.
To wit:
I am not sure (in fact, I am fairly certain to the contrary) that all sin is callous, cruel, stubborn, joyless, not to be sacrilegious, of course. I have enjoyed a few things that are considered sinful by one religion or another, to be candid, but not so often that I went blind.
alphabet of woe is a wonderful phrase. I wish that the previous line had substantiated it somehow.
the words of your mouth/and the memories of your heart is cliche-ridden and even nonsensical, although others will argue, perhaps, that words can come from elsewhere than your mouth, and that memories can come from other than your mind. I know, I know! It is a poem!
the desert in your heart is great, while the sacred from the profane is trite.
I don't know how one can be as numerous as the sands and the stars. I am hopeful to be enlightened.
morning will come, I first read as mourning will come, and find this provocative. It is right about at this point that I began to imagine politics and war and division and strife being a big part of this poem. "I didn't wanna do it," as the song goes, but right about there it happened. Visions of 1973. I will leave it alone, however.
It is in that light that I subsequently read remain standing, which makes that a much more powerful phrase, to my mind, albeit, perhaps, the most powerful one regardless of how you read the poem/sermon/lesson.
Take care.
