unleavenedness

The passover lamb was to be roast with fire, apparently that the analogy between it and the burnt-offering might be as far as possible complete. […] unleavened bread was to be eaten with it, leaven […] being generated of corruption, and so symbolic of decay and foulness; subsequently in the law, this prescription of unleavenedness was extended over all offerings of a cereal character: see Lev[iticus] ii. 11.

[T]he Passover day itself; Nisan 14, was commonly called the first of the unleavens, or the first day of the unleaveneds by all first century writers. Therefore, we can conclude, without a doubt that the Passover day was a full day of unleavenedness, most particularly bread.

The Englishman will not adapt himself to his surroundings; he is not in the least bit an imitative animal; he will be nothing but an Englishman, and is out of place—an anomaly—in any country but his own. […] In this country he is too generally arrogant, fault-finding, and supercilious. The very traits of loudness, sharpness, and unleavenedness which I complain of in our national manners, he very frequently exemplifies in an exaggerated form.

As [John] Chrysostom and Anselm [of Canterbury] say, as by baptism you were made unleavened, i.e., pure from the leaven of sin, so consequently you are, or ought to be, from thenceforth unleavened, or pure and holy, by calling and profession. […] This unleavenedness of heart and life is put before each one at baptism, both in words and ceremonies, by the Church, […]

Don't go back and live the way that you lived. If it comes back, starts to creep back, that's just like leaven growing in your life—get rid of it. Put in the unleavenedness of Christ. And that unleavenedness comes through the Spirit of God, as obedient children, see.

Throughout the night: we eat matzah (and more!), recalling the reality of our unleavenedness in Messiah; we pray, as the Master exhorted His disciples, so that we will not soon fall again into temptation; and we keep vigil, remaining physically and spiritually awake, in honor of the vigil that our Father once kept for us.
