(_Ibid._, 32, 6.) "But 'superfluous' and 'necessity' are to be interpreted according to their most probable and generally accepted meaning. 'Necessary' has two meanings. First, it implies something without which a thing cannot exist. Interpreted in this sense, a man has no business to give alms out of what is necessary to him; for example, if a man has only enough wherewith to feed himself and his sons or others dependent on him. For to give alms out of this would be to deprive himself and his of very life, unless it were indeed for the sake of prolonging the life of someone of extreme importance to Church and State. In that case it might be praiseworthy to expose his life and the lives of others to grave risk, for the common good is to be preferred to our own private interests. Secondly, 'necessary' may mean that without which a person cannot be considered to uphold becomingly his proper station, and that of those dependent on him. The exact measure of this necessity cannot be very precisely determined, as to how far things added may be beyond the necessity of his station, or things taken away be below it. To give alms, therefore, out of these is a matter not of precept, but of counsel. For it would not be right to give alms out of these, so as to help others, and thereby be rendered unable to fulfil the obligations of his state of life. For no one should live unbecomingly. Three exceptions, however, should be made. First, when a man wishes to change his state of life. Thus it would be an act of perfect virtue if a man, for the purpose of entering a religious order, distributed to the poor for Christ's sake all that he possessed. Secondly, when a man gives alms out of what is necessary for his state of life, and yet does so knowing that they can very easily be supplied to him again without much personal inconvenience. Thirdly, when some private person, still more when the State itself, is in the gravest need. In these cases it would be most praiseworthy for a man to give what seemingly was required for the upkeep of his station in life in order to provide against some far greater need."
