Some traditional wedding style poems include "To My Dear and Loving Husband," by Anne Bradstreet, and "The Good-Morrow," by John Donne. Anne Bradstreet's poem discusses marital happiness on earth and in the hereafter, while John Donne's poem describes the joy of finding a perfect love match and being unable to imagine life any other way, as expressed in this line from the poem, "“I wonder, by my troth, what thou and I did, till we loved?”
One of the most popular choices is the Bible passage from 1 Corinthians 13:4-7: "Love is patient, love is kind." However, wedding poems can be spiritual, non-spiritual, personalized or even turned into a children's story. A few examples of non-spiritual poems are "A Sonnet of Sonnets," by Christina Rossetti, and "I Would Live in Your Love," by Sara Teasdale.
"A Sonnet of Sonnets," tells a story about the strength of love, beginning with the line, "I lov'd you first: but afterwards your love / Outsoaring mine, sang such a loftier song." Teasedale's "I Would Live in Your Love," is summed up well by its title, as can be seen here, "I would beat with your heart as it beats, I would follow your soul as it leads."
A few more poems with famous author's to consider are "from Endymion" by John Keats, and "Sonnet CXVI: Let me not to the Marriage of True Minds," by William Shakespeare. If the poem will be used for a toast, then a few good options may be "Invitation to Love," by Paul Laurence Dunbar, or "A Blessing for Wedding," by Jane Hirshfield.
