People who frequently read this blog know that I have many posts clearly explaining why the animal sacrifices in the Bible were not 'taking the punishment the sinner deserved' (Penal Substitution). In this brief post I want to share a most significant aspect that is typically overlooked entirely.
Many folks think the animal's getting slaughtered for sacrifice were 'paying the price' for the individual's sins, so that the individual would not have to 'pay the price'. But the simple fact is, animals were not free (cf 2 Sam 24:24). Whether you raised animals or whether you had to buy them, there was a noteworthy cost. I estimate that a lamb would cost around $300 dollars. Because finances were a factor in whether someone could meet their obligation, the Law makes room for those who could not afford a lamb, e.g., those who could only afford two pigeons (Lev 5:7), or even those who could only afford a sack of flour (Lev 5:11). The point remains though, even if scaled down, the person who sinned (unintentionally) was going to take a financial hit of $300 dollars (or equivalent) each time. That's not chump change, and it can add up.
Imagine getting a $300 speeding ticket every month of the year (which is like a monthly car payment). That would be around $3,600 in fines per year. Thus, if you're an Israelite paying a few thousand dollars for animals each year, that's definitely a significant punishment. Financial punishments are no joke. And in the context of Penal Substitution, we can see that an Israelite taking the financial punishment, not to mention the time investment, means they were the one 'paying the price' for their sins. It makes little sense to think the animal being killed was being punishment in your place when just prior to the slaughter you had to pay $300 which you worked hard to earn. If someone was making minimum wage and working 40hrs per week, then to sin within the Levitical system meant you lost wages for basically a whole week of work! You definitely didn't escape personal punishment as an Israelite. And Leviticus 6:5 (Lev 5:16) explains that if you defrauded a neighbor, you had to pay back that amount, plus an additional 20%, plus offer a sacrifice! Ouch!
In closing, I should add that such a system seems unjust for God to put people under. The fact is, this 'burden' was not originally part of what God expected of them, but rather many of these rules and regulations were placed upon the Israelites only after they kept turning to sin. St Thomas Aquinas and other theologians explain that by putting all these expectations upon them, God was trying to not leave them with any time or resources to turn back to idolatry. But, this was only a temporary fix, as the real problem was an interior one, of the soul, which requires the Sacrifice of Jesus to heal.
