Whether it is lawful to be solicitous about temporal matters?

Objections

Objection 1 : It would seem lawful to be solicitous about temporal matters. Because a superior should be solicitous for his subjects, according to Rm. 12:8, "He that ruleth, with solicitude." Now according to the Divine ordering, man is placed over temporal things, according to Ps. 8:8, "Thou hast subjected all things under his feet," etc. Therefore man should be solicitous about temporal things.
Objection 2 : Further, everyone is solicitous about the end for which he works. Now it is lawful for a man to work for the temporal things whereby he sustains life, wherefore the Apostle says (2 Thess. 3:10): "If any man will not work, neither let him eat." Therefore it is lawful to be solicitous about temporal things.
Objection 3 : Further, solicitude about works of mercy is praiseworthy, according to 2 Tim. 1:17, "When he was come to Rome, he carefully sought me." Now solicitude about temporal things is sometimes connected with works of mercy; for instance, when a man is solicitous to watch over the interests of orphans and poor persons. Therefore solicitude about temporal things is not unlawful.
