Verse 33: the Parable of Leaven in Three Measures of Meal AT 13:33{This Time, It Is a Woman That Is Featured. She Hides Leaven in Three Measures of Meal (Flour) Until the Whole Thing Is Leavened. Again, the Word of God Is Its Own Interpreter. Throughout the Scriptures, Leaven Is Employed As a Figure for Evil, Whether Moral, Doctrinal, or Ecclesiastical. It Is so Whether in the Political, Legal, or Rational Arenas of Thought and Action

Furthermore, as already observed, it is a woman that introduces leaven into this loaf. It is however not permitted that a woman teach or exercise authority over a man, whether in the assembly or elsewhere. (See 1 Cor. 14:34-5 and 1 Tim. 2:11-12.) Now then, in the New Testament Scriptures, the assembly (whether true or false) is depicted everywhere as a woman. Doubtless therefore, this woman represents any system that takes the place of being the assembly and, therefore, of a woman. Nevertheless, she assumes the place forbidden to women and becomes a teacher of spiritual things. (It is often said, "the assembly teaches this or that." The assembly, however, doesn't teach, it is taught. It is taught by the teachers given it by its ascended Head. See Eph. 4:11) In doing so then, she introduces both doctrine and practices that are contrary both to God and to His Word.(See Rev. 2:18-23.). Thus, evil is introduced into the profession of Christianity, which evil will continue on and will spread until the whole thing is leavened.
The ultimate realization of this condition of things though will take place only after the rapture. At that point, every true believer will have been taken out of the world and up into heaven, leaving only those whose profession of Christianity is false. Then, while there will still be that in the world that claims to be Christian, the profession will be altogether empty. There won't be a single true believer left in it. Accordingly, the entire thing will have become leavened and an object for the judgment of Christ (See Rev. 17-18 in their entirety.).
