The Jewish Way, Rabbi Yitz Greenberg
In laughing at religious forms and at reality, one admits the fallibility of religious hopes but one also affirms them ... But why on Purim do Jews satirize their own traditions and not just those of the evil ones? The answer is that the ultimate Jewish claims of faith are truly dissonant with the world as humans know it ... True faith is neither oblivious to the facts that contradict nor afraid to affirm that the vision will finally triumph. Human makes statements about faith credible without being insensitive to present states of suffering. Through humorous affirmation, Jews admit that they follow God not because of their hopes have been realized but because they have trust in the Divine.
Two brothers came to the marketplace. Elijah said to Rabbi Beroka: These two also have a share in the World-to-Come. Rabbi Beroka went over to the men and said to them: What is your occupation? They said to him: We are jesters, and we cheer up the depressed. Alternatively, when we see two people who have a quarrel between them, we strive to make peace.
כי הא דרבה מקמי דפתח להו לרבנן אמר מילתא דבדיחותא ובדחי רבנן.
That explanation is like that which Rabba did. Before he began teaching halakha to the Sages, he would say something humorous and the Sages would be cheered.
Rashi’s Commentary on the Babylonian Talmud, 30
"The Sages would be cheered:" Their hearts were opened because of their joy.
