Whether religious perfection is diminished by possessing something in common?

Objections

Objection 1 : It would seem that religious perfection is diminished by possessing something in common. For our Lord said (Mt. 19:21): "If thou wilt be perfect, go sell all [Vulg.: 'what'] thou hast and give to the poor." Hence it is clear that to lack worldly wealth belongs to the perfection of Christian life. Now those who possess something in common do not lack worldly wealth. Therefore it would seem that they do not quite reach to the perfection of Christian life.
Objection 2 : Further, the perfection of the counsels requires that one should be without worldly solicitude; wherefore the Apostle in giving the counsel of virginity said (1 Cor. 7:32): "I would have you to be without solicitude." Now it belongs to the solicitude of the present life that certain people keep something to themselves for the morrow; and this solicitude was forbidden His disciples by our Lord (Mt. 6:34) saying: "Be not . . . solicitous for tomorrow." Therefore it would seem that the perfection of Christian life is diminished by having something in common.
Objection 3 : Further, possessions held in common belong in some way to each member of the community; wherefore Jerome (Ep. lx ad Heliod. Episc.) says in reference to certain people: "They are richer in the monastery than they had been in the world; though serving the poor Christ they have wealth which they had not while serving the rich devil; the Church rejects them now that they are rich, who in the world were beggars." But it is derogatory to religious perfection that one should possess wealth of one's own. Therefore it is also derogatory to religious perfection to possess anything in common.
Objection 4 : Further, Gregory (Dial. iii, 14) relates of a very holy man named Isaac, that "when his disciples humbly signified that he should accept the possessions offered to him for the use of the monastery, he being solicitous for the safeguarding of his poverty, held firmly to his opinion, saying: A monk who seeks earthly possessions is no monk at all": and this refers to possessions held in common, and which were offered him for the common use of the monastery. Therefore it would seem destructive of religious perfection to possess anything in common.
Objection 5 : Further, our Lord in prescribing religious perfection to His disciples, said (Mt. 10:9,10): "Do not possess gold, nor silver, nor money in your purses, nor script for your journey." By these words, as Jerome says in his commentary, "He reproves those philosophers who are commonly called Bactroperatae [*i.e. staff and scrip bearers], who as despising the world and valuing all things at naught carried their pantry about with them." Therefore it would seem derogatory to religious perfection that one should keep something whether for oneself or for the common use.
