Passover was the original repudiation of the pagan mindset that still holds true today. It reminds us that we can all escape tyranny, no matter our circumstances, because true slavery and freedom take place on the battlefields of the soul. Slaves can triumph over tyranny if they believe and free men can fall to much weaker tyrants (or become them) when they do not.
Judaism has many holidays, but Passover is the first of them because without spiritual liberation, nothing else truly matters. Only those who are free in spirit can serve G-d. Freedom, like faith, is easy to preach, but difficult to attain. At the Passover seder, families, friends and strangers will come together to once again experience slavery, to taste salt water, bitter herbs, and the mortar that bound bricks together, and to drink wine and sing like free people.
Free people all too easily forget what freedom is and where it comes from. Only when we confront tyranny, when we experience the loss of what we had, can we truly appreciate it.
Passover immerses Jews in the tyranny of paganism and the liberation of G-d. It is not merely a memorialization of the past, or the anxieties of the present, but the promise of the future. Keeping the faith means knowing, as the Jews of Egypt or those in Auschwitz did, that there is more to the world than the power of any tyrant: to his chains, laws and social credit systems.
To truly keep the seder is to know, as they did, that there is a power above them all that knows, that sees and that acts even when everything appears to be going wrong and to be doomed.
As the slaves gathering in secret along Egyptian canals, whispering an impossible hope to each other, and as their descendants, sitting for thousands of years at the seder, feeling free no matter how much in chains, believed, G-d is coming, not just to liberate us, but to set us free.
