8 The Church has always valued, and still does, the devotion to the Most Sacred Heart of Jesus so highly that she provides for the spread of it among Christian peoples everywhere and by every means. At the same time she uses every effort to protect it against the charges of so-called "naturalism" and "sentimentalism." In spite of this it is much to be regretted that, both in the past and in our own times, this most noble devotion does not find a place of honor and esteem among certain Christians and even occasionally not among those who profess themselves moved by zeal for the Catholic religion and the attainment of holiness.
