75 The Sacred Heart of Jesus shares in a most intimate way in the life of the Incarnate Word, and has been thus assumed as a kind of instrument of the Divinity. It is therefore beyond all doubt that, in the carrying out of works of grace and divine omnipotence, His Heart, no less than the other members of His human nature is also a legitimate symbol of that unbounded love.(78)
