Basil of Caesarea — as excerpted in the Catena Aurea on Luke 6:20-23

“(in Ps. 33.) But not every one oppressed with poverty is blessed, but he who has preferred the commandment of Christ to worldly riches. For many are poor in their possessions, yet most covetous in their disposition; these poverty does not save, but their affections condemn. For nothing involuntary deserves a blessing, because all virtue is characterized by the freedom of the will. Blessed then is the poor man as being the disciple of Christ, Who endured poverty for us. For the Lord Himself has fulfilled every work which leads to happiness, leaving Himself an example for us to follow.”
