I can't listen to poems. If someone is reading a poem in church, I can't tell you anything about the poem two minutes later. I just can't pay attention to poems in the slightest. I drift off as soon as someone starts reading. I get nothing out of a poem in church.
Maybe it's just me. Maybe I'm not a poem person. But I think this brings up a couple of issues. First the issue of readings used in worship. What is scriptural for Unitarians? When I heard that Unitarians didn't just use the Bible in worship I was excited at the prospect of hearing from the Qur'an or the Bhagavad Gita or Julian of Norwich every week. I was most disappointed, and have continued to be disappointed by the predminance of poems about flowers and such, rather than world religions and mystical texts.
Secondly in general I can't listen to a lot of stuff in church. My mind wanders most of the time. This is why when I am leading worship I have readings written down in an order of service to allow people to read along, and refer back to. This is what I was brought up with in the C of E, and this is what I believe works. But I've never seen any other Unitarian do it. I don't know why.
