Tertullian,
Ante-Nicene Fathers Vol. III, Apologetic…
(1885)
“ Or if it shall be necessary that the appointed days of life be fulfilled here on earth, must the same course of life in all its vicissitudes, which has been itself ordained to accompany the appointed days, be also passed through by the soul along with the days? Must it employ itself in school studies in its passage from infancy to boyhood; play the soldier in the excitement and vigour of youth and earlier manhood; and encounter serious and judicial responsibilities in the graver years between ripe manhood and old age? ”
