Religious themes

I agree with Artqueen when she says that On My First Sonne contains a lot of religious reference e.g. the idea that the poet committed a "sinne" to love his son so much.
Other poems with reference to religion could be Tichborne's Elegie, if only because he died for his religion, wanting Mary Queen of Scots, a Catholic, on the throne of England instead of Elizabeth.
There's also religious reference in Storm on the Island, if you want to see it as a metaphor for the conflict between Catholics and Protestants in Ireland (The Troubles), and in Clarke's poem A Difficult Birth, which refers to the Easter story (the stone rolled back from the tomb), and, I guess, to the Christmas story, in that it deals with a birth, and Jesus is called "Lamb of God" in the Anglo-catholic mass.
Any more ideas for links to religion in the anthology poems?
