Who wrote this poem love is enduring and patient kind it judges all things with the heart not mind?

The poem you've quoted is a paraphrase of a well-known passage from the Bible, specifically 1 Corinthians 13:4-7. It describes the qualities of love:

"Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres."

While this passage is often referred to as a poem, it is actually a portion of a letter written by the Apostle Paul to the church in Corinth.

So, the "author" of this "poem" is the Apostle Paul.
