"Spiritual age"

"NOW the soul, to which spiritual birth and perfect spiritual age belong, is immortal; and just as it can in old age attain to spiritual birth, so can it attain to perfect (spiritual) age in youth or childhood; because the various ages of the body do not affect the soul."

~St. Thomas Aquinas: S.T. III, Q. 72, A. 8. (The sacrament of Confirmation)
