One of the most popular devotions among Catholics is the devotion to the Sacred Heart of Jesus. However, some might claim that the devotion has no basis in the Bible.
Sacred Heart in the Bible
In reality, devotion to Jesus' Heart is supported by many biblical passages. The Directory on Popular Piety explains how this devotion is supported by the Bible.
The Directory then lists all the scripture passages that support the popular devotion.
In particular, the Gospel of John stands out as one of the primary sources of this devotion, based on the passages mentioned above.
While the exact term, "Sacred Heart of Jesus," is not found anywhere in scripture, the concept of Jesus' Heart, poured out for all humanity, is present in the New Testament, especially in the Gospel of John.
