Catholics who discover Father Edward Leen's Grace and the Supernatural Life for the first time in paperback form will have reason to be grateful to the publishers for reissuing it as a Canterbury Book. (Originally it was titled The Holy Ghost.) Father Leen examines supernatural grace as a real supernatural quality inherent in the soul, not making the soul simply good but making it, in a sense, divine. He shows how the Holy Ghost is the link between creature and the Creator, because he establishes the real friendship between God and man. The gifts of the Holy Ghost, Father Leen feels, are God's divine inventions to elevate man to the perfection to which he is called. An excellent chapter on ""The Fruits and the Beatitudes"" rounds out a valuable book.
