It is not the proper duty of Christianity to form leaders - that is, builders of the temporal - although a legion of Christian leaders is infinitely desirable. Christianity must generate saints - that is, witnesses to the eternal.
The efficacy of the saint is not that of the leader. The saint does not have to bring about great temporal achievements; he [or she] is one who succeeds in giving us at least a glimpse of eternity, despite the thick opacity of time. - Father Henri de Lubac, S.J.*
