Christian poetry, also called spiritual poetry, is narrowly-focused subject matter that can make publishing a challenge. Christian poets, especially, find it difficult to make a living on selling their poetry alone as this type of poetry is written more for the love of writing and glorifying God than for profit. If you write spiritual poetry and want to share it with others, whether for profit or simple exposure, using as many opportunities as you can find is the most effective way to get your work published.
Purchase a copy of the "Poet's Market" and formulate a list of your publishing options. The "Poet's Market" is a resource book for poets that includes a large section on Christian poetry markets, which lists publishers who accept Christian poetry and gives complete contact details and submission guidelines. Compiling a list of suitable markets for your work from this book is the most effective way to find paying markets for your Christian poetry.
Search the Internet for online Christian poem publishing markets and associations for Christian writers. Because the market for Christian poetry is narrow in comparison to other types of writing, getting involved in a Christian writer's association can help you build a strong network. In Christian writing, the atmosphere of fellowship is such that other writers share ideas and publishing venues. A strong network will be invaluable for getting your work in print or performed at Christian events.
Contact Christian churches and organisations with a short letter of introduction. The letter should be brief and give a short bio of you and your writing credits. Offer to allow the church or organisation to publish your poetry in church newsletters or in weekly church handouts. This publishing avenue will likely not be a paying opportunity, but it's an effective way to publish your Christian-oriented work to a wide audience. This visibility can help you build your name as a Christian poet, which helps build your resume.
While you're waiting for your Christian poetry-writing career to take off, consider writing inspirational poetry in the meantime which can provide you with a way to earn money while you continue to pursue Christian-based markets for your Christian poetry. Inspirational poems carry a spiritual message without being aimed at a specific religion. These poems are more likely to sell to mainstream greeting card markets.
