The tradition [sacramentality in the Catholic tradition] has long held a reverential place for the concrete ways in which God can be manifest through the material. Thus one can point to the "sacramentals," the historical veneration of relics, the concern for visible expressions of one's piety such as processions, house blessings, devotions, veneration of the saints, and, in moral theology, a particular concern for the ways in which the human body can be seen to point toward God. According to the sacramental principle, human beings find God not by leaving or denying the world, but by becoming immersed more deeply in it.
