Among the many proofs of the boundless benignity of our Redeemer, there is one that stands out conspicuously, to wit the fact that when the charity of Christian people was growing cold, the Divine Charity itself was set forth to be honored by a special worship, and the riches of its bounty was made widely manifest by that form of devotion wherein worship is given to the Most Sacred Heart of Jesus, "In whom are hid all the treasures of wisdom and knowledge"
(Coloss. ii, 3).
