We can and should come to God with all our senses, not just with the intellect. That is why God gives himself to us in earthly signs – especially in bread and wine, the Body and Blood of Christ. [1084, 1146-1152]
People saw Jesus, heard him, could touch him and thereby experience salvation and healing in body and soul. The sensible signs of the -> SACRAMENTS show this same signature of God, who desires to address the whole man – not just his head.
