Nothing in the Bible teaches that “love overcomes all.” But there are passages and chapters in the Bible, such as Romans 8:37, 1 Corinthians 13, 1 Peter 4:8, and Matthew 22:36–40, that are nearly equivalent in terms of significance.
The Latin author Virgil’s Eclogues X.69 has the following statement, which is the source of the expression “love conquers all”: “Omnia vincit amor et nos cedamus amori.” It means “let us all submit to love for love overcomes all.” Geoffrey Chaucer, an English poet of the Middle Ages, later rendered the first part of the phrase as “love conquers everything,” and it later into common usage.
