Richard Rolle was a 14th century English mystic and hermit, notable for the spiritual fervor and devotion of his prolific writing about the soul's love for, journey toward, and ecstatic union with God. His writings were extremely popular, treasured by unlearned laypeople and by those in religious vocations, both for the spiritual renewal he encouraged by his instruction and for the lyricism or accessibility of his language: wanting to reach a wide audience, he wrote in Latin and in English, the first English mystic to write in his native tongue.
One of his quotes reminds of the importance to love God and people, not things, as we embody what we worship and become more like what we bestow our affections on: “What is love but the transforming of the desire into the loved thing itself? Every lover is assimilated to his or her beloved. Love makes the loving one, like what he or she loves.” Chapter 17 of The Fire of Love.
