Like Yeast

In Matthew 13:33 Jesus said, “The kingdom of heaven is like leaven” (yeast). What about yeast helps us understand the kingdom of heaven? The woman used, three measures, about 27 kilograms (60 pounds). That is far more bread than one family needs, “a woman took and hid [it] in three measures of meal till it was all leavened.” Could this refer to the three major branches of Christianity: Catholic, Orthodox and Protestant? Is it Christianity or idolatry which creates human traditions and doctrines contradicting the teachings of Jesus? Only Jesus has the authority to define the kingdom of heaven, and He defines it as much larger than our narrow views.
