Do you like being supervised? I imagine not. It doesn’t really matter whether we are being formally assessed (at work, in a medical test, even in sport), or just have someone looking critically over our shoulder – it makes for stress, if not resentment.
It should not be too difficult to understand Paul (Galatians 3:23-29), when he speaks of the Old Testament Law as a “guardian”. Yes, the Law tells us what God is like, and how our lives should go to fit God’s intentions and our purpose. But like a schoolteacher, it can limit our freedom, and doesn’t actually make us good at learning. We are reminded that children in the first century were sometimes under the control of a slave, who made sure they behaved and did their lessons, even though the slave had no status himself. The slave was hardly a friend, no matter how properly he did his job.
So, Paul suggests, becoming Christians is like gaining the freedom of family members. No longer subject to strict control, we share with other believers the equal status our faith releases. In this letter, Paul has been concerned to reject the demands of some who claimed that non-Jewish converts to Christ had to observe all the Jewish Law and customs. He insists (as did the Council of Jerusalem, under the guidance of the Holy Spirit, in Acts 15) that while Gentile believers in Christ should be concerned to maintain fellowship with Jewish believers, they do not have to live under Jewish regulations.
The freedom of the Christian is still important, and easily lost to judgmental attitudes or old fashioned habits. Yes, we need to understand how our lives are to be like Jesus’, showing the effect of the Holy Spirit. Yes, the Old Testament remains important for us to understand God’s interactions and relationships with humans through the ages. But no, we don’t have to follow endless restrictions and traditions. Getting it right is difficult, but important.
