“The kingdom of heaven is like leaven which a woman took and hid in three measures of flour, till it was all leavened” (Matthew 13:33). • We know that yeast is nothing but single-celled microorganisms that multiply by division, and they don’t even leave sugar without turning it into alcohol, much like evil transforms consciousness into unconsciousness. The holy revelation used yeast as a symbol of evil, as seen in Matthew 16:11, Mark 8:15, and 1 Corinthians 5:6-8. When His people left Egypt, He commanded them to take their dough before it leavened. Yeast, being singular, symbolizes isolation, while the people would not be alone. So how could they carry yeast, which symbolizes separation from God and evil division, while God surrounds them from the front and the back? How did this single-celled organism that reproduces by division become a symbol of the Kingdom of Heaven? Has the nature of yeast changed, or is there a hidden mystery? • Yeast is a microorganism, and humanity, before salvation, took on all the traits of yeast and carried all the microbes of evil. Man was isolated, like the yeast cell, separated from God. Man’s wickedness increased, just as a yeast cell divides and multiplies. • The cup overflowed with yeast, so the Lord washed the earth with the flood to create a new, alternative yeast, for yeast dies in water. The new yeast is born of water, which is why we are baptized in the name of the Trinity. • But how did yeast become worthy of the Kingdom? It was first due to the three measures of flour, and secondly due to the woman who took the yeast and placed it in the three measures. When the (yeast), meaning the isolated human, united with the (three measures), meaning the Trinity, through the (flour), symbolizing the incarnation of the Son, man was no longer a single-celled organism. He no longer multiplied by division but rose through union, just as flour rises with yeast. Through the incarnation of Christ, our Lord of glory, we no longer distinguish between the yeast and the flour, nor between divinity and humanity in the person of the incarnate Lord. • The flour rose with the yeast, and the yeast rose with the flour. Through the union of Christ with our nature, we were elevated with Him, by Him, and in Him. Yeast no longer grows by self-division but by divine union in the Father, Son, and Holy Spirit. This is the Kingdom of Heaven. • The woman who took the yeast is the Church. She also used water and the Spirit to abolish the old nature of yeast through baptism. She partakes in the nature of Christ as man is grafted into the three measures, that is, the Persons of the Trinity. The Kingdom is communion, while hell is separation. In all the parables of the Kingdom, yeast becomes part of the whole, and all the flour is leavened with the heavenly flour, Jesus Christ, our living Bread, and the same three measures of the Holy Trinity. • When the old yeast tries to attack us, trying to destroy its sweetness and turn sugar into alcohol, its work vanishes as the Holy Spirit stops it and grants new life. He teaches the new nature, causing one to love even their enemies and reject quarrels and divisions. He delights in the life of the yeast of the Kingdom because it is heavenly, not earthly. You are this yeast. • O our incarnate God, holy yeast of the new Church, who penetrates His people through the Holy Spirit, dwelling in them and clothing them in His heavenly nature, lifting them to what is unseen. We pray to You to abolish the old yeast, so that after we have united with the three measures, we are not torn away and return to our old state, squandering all sweetness within us. Do not let the old yeast spread its divisions in the Church, but have mercy on it and allow it to unite with the three measures. Open the eyes of the woman entrusted with the new birth, so she may see every old yeast and, with gentleness, take it to unite with the flour and connect it to the Trinity without interruption. Then the corrupt will be abolished, and we will put on the heavenly. The divine Bread will raise us, and we will become holy yeast, both for ourselves and for all.”
