The cares of the world ( τοῦ αἰῶνος); literally, of the age; that is, temporal and secular cares, incident to the age in which our lot is cast, and which are common to all. These, like thorns, distress and trouble, and often wound the soul; while, on the other hand, the care of the soul and the thought of heavenly things compose and establish the mind.
The deceitfulness of riches. Riches are aptly compared to thorns, because, like thorns, they pierce the soul. St. Paul (1 Timothy 6:10) speaks of some who, through the love of riches, "have pierced themselves through with many sorrows."
Riches are deceitful, because they often seduce the soul from God and from salvation, and are the cause of many sins. "How hardly," says our Lord, "shall a rich man enter into the kingdom of God I" They have a tendency to choke the Word of God, and to weaken the power of religion.
"Those are the only true riches," says St. Gregory, "which make us rich in virtue."
