Sacred Heart
Early Christians, for example John the Evangelist and Paul of Tarsus, wrote the first devotions or prayers to the love of God. The earliest devotions to the Sacred Heart of Jesus were from the Benedictine or Cistercian monasteries. St. Bernard of Clairveaux from the Cistercian religious order was the first person to write a devotion to the Sacred Heart of Jesus, but some people believe that the first person was St. Anselm.
