Here's the link for the opening ceremony video (chalice lighting starts at the 22:43 point in the video. The chalice lighting was delivered by Rev. Fritz Hudson, minister of the Unitarian Church of Lincoln, Nebraska.
Here's the text of his chalice lighting as printed on the UUA web site (line breaks added to make it easier to read and I've edited the web site text to better match the words spoken on the video recording - changes are within the brackets):
Into the circle of the wide prairie sky, we come together, each of us casting our personally unique circles.This reading from this minister seems so full of Midwestern earnestness that I don't think his intention was sexual innuendo.
—we come carrying around us the circle of those whom we love
—we come carrying upon us the circle of those whom we represent
—we come carrying within us the circle of our apprehensions & our aspirations.
Circles, in motion, whose borders touch—may repel each other, may hold their borders, may demand separate space for separate accommodation,
Or circles, in motion, whose borders touch, with a little push, a little release, may overlap
[May inter-penetrate], can even seek each others' center.
There's friction in such [inter-penetration], as circles pass through circles.
But, in all the rubbing, should two circles' centers find each other, touch, rub
the spark, the spark [like a prairie star]
can ignite a holy prairie fire.
But even if he were using sexuality as a metaphor in liturgy (which may be a more constructive way to frame this than calling it "sexual innuendo"), is this a bad thing?
If your answer to this question is "yes," why do you think it's a bad thing?
I certainly hope the answer isn't some variation of "what will the neighbors think?"
