5 Reasons Why We Should Still Read The Book of Leviticus Today
I just finished reading the Book of Leviticus this morning for the second time this year on my quest to finish two canonical readings for 2012. In honor of that reading, I have finally published my next list page (see my list of lists), called the 613 Mitzvot Laws or Commandments of the Old Testament, many of which are found in the book of Leviticus.
Leviticus is one of those books that Christians tend to want to ignore, while those in the opposite camp tear it apart Hebrew letter by Hebrew letter. About a year ago I actually debated with another Christian about the worth of even reading this book, and he was convinced there was nothing of importance or worthy in Leviticus for us to read today. This was no uninformed, unintelligent Christian, he has a PhD, is a leading scientist in his field, and has a heart for important social justice issues, but Leviticus was not for him (nor really any of the Pentateuch). At that time I did a lousy job at explaining why this book, and every one of the 66 books of the canon, are all still very important and relevant to read in the 21st century. Since that conversation I've never really been able to rectify my lack of knowledge in Leviticus and reasons why it is important to read.
This second go-round I started reading Leviticus back on August 14th and finished up today, August 21st, so reading the entire book does not take that long if you read a little bit each day. I will say, Leviticus is not a very difficult book to read, but it is a difficult book to understand, especially in light of our culture today. We are so far removed from the customs of the sacrificial systems and just overall life during the 13th-15th century B.C., it's very hard for us to understand, within the proper context, how to apply Leviticus to our life today without reading, study, contemplation, and meditation on these 24 chapters.
So here are a few reasons why all Christians should still read this book today. I'm going to skip the obvious reason of because it is part of the canonical Bible, and go on to others, but this is first and foremost. We should read it, because it is part of the writings given to us by God himself through Moses.
Reasons We Should Still Read Leviticus Today
1. It's the Enemy's Favorite Book to Tear Apart (Think Shellfish, Polyester, Tattoos, and Homosexuality) They, the enemies of Truth, call it a book full of contradictions and hypocritical living. This is generally because they don't understand the book in context any more than we do, but they can read the obvious to make stupid arguments like Christians still eat pork and wear polyester, therefore homosexuality is not a sin (see Homosexuality, Polyester, and Shellfish for reasoning behind this tired debate).
Apologetically speaking, we should know what this book says, because it is used as an excuse for everything under the sun in the 21st century. The book has a great narrative that is often overlooked by the fact that it is a list of laws. These "laws" range from capital punishment for adultery, to not cutting your hair, to laws on homosexuality, to not getting a tattoo because it follows the evil Canaanite tribal practices. Why is it acceptable for Christians to get a tattoo, or eat pork, but not put adulterers to death? Understanding this book in proper context shows exactly why some laws are historically customary for their culture and time, and why some are moral obligations that transcend time.
2. The Theological Holiness Code Developed in Leviticus is Still Used Today In 1 Peter 1.15-16 the Apostle Peter says, "but as he who called you is holy, you also be holy in all your conduct, since it is written, "You shall be holy, for I am holy." That is a direct quote from Leviticus 11.44, which is then repeated several times such as in Leviticus 19.2. In seminary circles this is called the "Levitical Holiness Code" from chapters 17-27. It mainly deals with the idea of sanctification, the idea of holiness affecting how one lives in the covenant community.
For Christians today living in the 21st Century, the New Testament applies to Christians using the same principles of life stated in 11:44, and many of the "holiness codes" still show us what is displeasing to God (cf., 19:11-18, 35-36). On the other hand, as noted above, there are also symbolic aspects of the holiness code we no longer follow such as prohibiting garments of two different kinds etc.
3. To Understand How the Work of Christ Saves the Soul Studying Leviticus today gives us an extremely important understanding of the sacrifice that Jesus made as the Christ when he died on the cross. The animal sacrificial system may be totally foreign to us now, but this enables the 21st century reader to understand why Christ's sacrifice is one of salvation.
4. The Festal Calendar of Israel in Leviticus Shaped the Christian Calendar We Still Use The three main festivals, or sometimes called the national pilgrim feasts of Israel, are the Feast of Unleavened Bread, the Feast of Harvest, and the Feast of Booths. Most of our modern day church denominations from Baptist to Catholic still follow these festivals. These celebrations today find their climax in the corresponding days known as Good Friday, Easter, and Pentecost.
5. Because Without Leviticus the Other 65 Books Don't Make Any Sense Every book is intertwined with every other book. This is a huge reason to me. If you are reading Kings or Nehemiah, or one of those other "important" books, you are reading part 11 or part 16, but you never read part 3. Knowing and understanding Leviticus is crucial to understanding any of the other books, just the same as reading and studying Kings is important to reading Matthew.
What sense does Christ being crucified on the cross make without knowing how the sacrificial system works? I understand you can watch the Lord of the Rings or the Star Wars movies out of order and you can still understand them individually, but don't they make a whole lot more sense as a whole?
So there you have it. Five reasons why Leviticus is important for us to read today. I know these points aren't developed very extensively, but it that wasn't really the point.
