Pastor Uriesou Brito writes this, concerning the book of Leviticus:

I was trying to do the impossible this morning listening to Leviticus. I attempted to listen to it through the eyes of an atheist–to see laws about priestly purity, eye defects, dwarfs, damaged private parts, and other bodily oddities that needed to come into conformity to the holiness code. As a supposed atheist I imagined mocking such texts and the grotesque descriptions and the absurd necessity to conform to such laws simply because of our humanity. Why should purity laws apply to menstruating women when it is merely the natural function of a female body? Why make her unclean for something she has no control over? How barbaric to apply standards to the regularity of life!

But the more you read into Leviticus the more impossible it is to remove the Christian eye from its intended goal. If Leviticus borrows heavily from the strange it is because the Bible carries with it a seal of authenticity in every book, and especially Leviticus. There is an inherent “deep weird” to the Bible that Christians must embrace. We don’t embrace it because we delight in the oddity, but because for the world to be coherent, it must have elements of the strange within it. Bodily discharges—though unbearably odd to mention—is so common that only a truly Spirit-inspired book could deal with it so bluntly.

The Christian faith must be embraced as a Levitical faith; one that is not shy of rituals and impurity and rituals for purity. It must also be embraced to reveal the vast contrast between the care God has for the well-being of his people and just how uncaring the gods of this world are about our well-being. Only a true God provides a system of symbols, rituals, death, and resurrection for his people. Indeed, Leviticus provides the route to holiness and our need for a Holy God.

As Paul says in Romans, the unbeliever cannot see the truth because he is blind. Perhaps Leviticus serves as a test for ordinary Christians on whether we embrace the raw language of Scripture as God’s reality or whether we prefer to sanitize the faith to fit our preconceived notions of reality. The Leviticus code is a pointer to the cleansing of the nations. There is no life without blood and there is no atonement without holiness. Leviticus is the pathway to the cross where the Holy One absorbs all our impurities, and simultaneously it is the aroma that draws true Israelites to the house of Yahweh. For the atheist, it is sheer absurdity, but for the Christian, it is the way of life and holiness and truth.
