A spiritual life to be lived by human beings requires them. We are not angels. We have both a soul and a body, and religion must cater for our complete needs. We live by our senses, and acquire our certainty from sense data. Significant symbols, and rites and ceremonies play a big part in the individual and social lives even of those who object to our religious rites. God Himself respects our twofold spiritual and material nature, and leads us to Himself by means on our own level. The soul uses the bodily powers in God's service, and God uses the bodily rites called the Sacraments in communicating grace to men. He wishes to sanctify man just as man was made by Him.
God employed material forces in our creation, and He employs them to recreate us in grace. It is quite normal that a material element should intervene in both cases. In our natural lives we use the forces of God immanent in nature. The Sacraments are the forces proper to God in our supernatural and spiritual lives.
He is. But we are flesh. And we have to rise above the flesh to a spiritual plane, from the natural level to the God-level. To enable us to do so, the Eternal Son of God came down to earth and took flesh, obviously setting before us and using a material nature for our spiritual regeneration. It is quite in harmony with this that material and visible Sacraments should be used to continue the work of our spiritual regeneration.
