SECOND EDIT: Sermon on the Destruction of Icons

[Kubla Khan]

"... for five hundred years, during which religion was in a more prosperous condition, and a purer doctrine flourished, Christian churches were completely free from visible representations" - John Calvin, Institutes of the Christian Religion

From Eve in vines about her legs,
Like fetters forged in Paradise,Really like the first line. Kudos on that. But, (and I am certainly not one to give advice on punctuation) is the comma needed after the first line?
To Saintly men in grief reposed, is grief reposed an enigma? I'm not going to insinuate I know what I'm talking about, but that doesn't seem right to me.
And God Himself a sack of rice,
Slid limply in His mother's arms.
I really don't understand this stanza, whether that is indicative of "dunciness" on my part, I don't know..

These are the idols John told us
Would bring to folly naive hearts. I dig this line, and it's composition a lot.
If hammers be the rage of Christ,
Let men destroy these morbid arts. These last two lines are somewhat unclear to me. I get it, but it is still not the most efficient I don't think

I speak to thee from place of stone, I Like the poetry of this line
A pulpit fit for cloistered sheep,
And this dark stone will teach thee well:
That Papist hearts will find no sleep.

Overall, it was a little too obscure, I thought. But none the less, I do like it.
