Christians are sometimes accused of being inconsistent in applying the Bible when we don't universally adopt the Mosaic Law. Christians often wonder what our relationship is to the Mosaic Law today. Here's a very helpful article.
In sum, the author explains that the Mosaic Law was meant for a particular nation that existed in a time and place so it doesn't automatically apply today. Also, divvying it into categories that apply in part is somewhat arbitrary and unhelpful, in the end. Instead, he argues that the Mosaic Law in its entirety had a temporal use, but it contains universal principles that apply at all times to all people and instructs us on what's important to God. He sums up some guidelines for sound application:
- Identify what the particular law meant to the initial audience
- Determine the differences between the initial audience and believers today
- Develop universal principles fromt the text
- Correlate the principle with the New Testament teaching
- Apply the modified universal principle to life today
