From The Gospel of Matthew by Curtis Mitch and Edward Sri, commenting on Matthew 25:24-27:
Confining ourselves to the storyline of the parable, the master’s rebuke seems excessively harsh. But if the talents represent each servant’s “knowledge of the mysteries of the kingdom of heaven” (13:11), then the severity of the charge is understandable. Being entrusted with the message of salvation entails great responsibility. To sit on that message or to bury it for ourselves is a serious breach of responsibility to the Lord, who calls us to share his good news with the world. He does not want us to give it back to him unshared and unfruitful.
