"A strong and truly apostolic soul is always calm, gentle, and unshakable in the midst of pains and contradictions. It is never sad, gloomy, agitated, abrupt, sullen, silent, nor a burden to itself or its neighbour. All these defects are the affairs of feeble souls, lovers of themselves, who do not know the virtue of the cross of Jesus Christ, and who do not wish to have a part in it. "

Francis Libermann (Cf. Spiritual Letters, IV, 458, 1847.)
