"[L]et us take our part in the Passover prescribed by the law, not in a literal way, but according to the teaching of the Gospel; not in an imperfect way, but perfectly; not only for a time, but eternally. Let us regard as our home the heavenly Jerusalem, not the earthly one; the city glorified by angels, not the one laid waste by armies. We are not required to sacrifice young bulls or rams, beasts with horns and hoofs that are more dead than alive and devoid of feeling; but instead, let us join the choirs of angels in offering God upon his heavenly altar a sacrifice of praise. We must now pass through the first veil and approach the second, turning our eyes toward the Holy of Holies. I will say more: we must sacrifice ourselves to God, each day and in everything we do, accepting all that happens to us for the sake of the Word, imitating his passion by our sufferings, and honoring his blood by shedding our own. We must be ready to be crucified."
~St. Gregory of Nazianzen
