I get that it’s a poem by a Christian, that it mentions feeling abandoned by God and the Virgin Mary, that it alludes to God-in-the-Whirlwind from Job in the context of enduring fury and desperation, and that religion is shown as a temporary respite in the end.
But that doesn’t sound like a poem encapsulating Christianity (Michael Masiello’s answer to How can I stop hating religions and God?); it sounds like a poem written by a Christian, having a crisis of faith in Christianity.
