Christianity has produced without any doubt men and women who have fulfilled in themselves the greatest potentiality of the human personality. In all the centuries of the Christian era there stand out men and women, and no small number of them, whom everyone felt were fully developed and integrated and whom mankind could take as patterns of the mature and develped personality. This has been more so than in any other period of history.

It is very true that it is the triumph of the life of Christ in these men and women that has brought them to holiness, maturity and integration; but in the process their psychological development has taken place. The life of grace does not by-pass nature but adds to it, and lifts it on to another plane.
