The meaning of the word “creative” is very precise here: it denotes the active contribution each soul is at liberty to bring to the universal work which is accomplishing itself in our world and doubtless far beyond it. In this connection the condition of a human being of whatever kind is not essentially different from that of the artists who is the bearer of some message which he must communicate, of some flame which me must kindle and pass on, like the torch-bearers of Lucretia. Everything seems to happen as though on the human level the operation of the flesh ought to be the hallowing of a certain inward fulfillment, an out-flowing not to be forced since it springs from an experience of plentitude. Perhaps I should make myself better understood by saying in a way which actually is not exclusively Christian that the operation of the flesh loses its dignity and degenerates from its true nature if it is not an act of thanksgiving, a creative testimony.
