One cannot help remarking that the theology of the manuals does not always make a careful distinction between that unique manner of existence which is peculiar to man, and the mode of being, mere objective being there, which is proper to the things of nature. The absence of this distinction particularly in treating of grace or the sacraments occasionally obscures the simple fact of encounter with God. The intimates of God's personal approach to man is often lost in a too severely objective examination of that which forms the living core and centre of religion the personal communion with the God who gives himself to men.
