Tim Keller on Old Testament Law and The Charge of Inconsistency

from Stand Firm by Sarah

So good, so clear, so thorough—people who use the shellfish argument regarding blessing sex between men or between women really are Biblical and Gospel-illiterates:

First of all, let’s be clear that it’s not only the Old Testament that has proscriptions about homosexuality. The New Testament has plenty to say about it, as well. Even Jesus says, in his discussion of divorce in Matthew 19:3-12 that the original design of God was for one man and one woman to be united as one flesh, and failing that, (v. 12) persons should abstain from marriage and from sex.

However, let’s get back to considering the larger issue of inconsistency regarding things mentioned in the OT that are no longer practiced by the New Testament people of God. Most Christians don’t know what to say when confronted about this. Here’s a short course on the relationship of the Old Testament to the New Testament:

The Old Testament devotes a good amount of space to describing the various sacrifices that were to be offered in the tabernacle (and later temple) to atone for sin so that worshippers could approach a holy God. As part of that sacrificial system there was also a complex set of rules for ceremonial purity and cleanness. You could only approach God in worship if you ate certain foods and not others, wore certain forms of dress, refrained from touching a variety of objects, and so on. This vividly conveyed, over and over, that human beings are spiritually unclean and can’t go into God’s presence without purification.

But even in the Old Testament, many writers hinted that the sacrifices and the temple worship regulations pointed forward to something beyond them. (cf. 1 Samuel 15:21-22; Psalm 50:12-15; 51:17; Hosea 6:6). When Christ appeared he declared all foods ‘clean’ (Mark 7:19) and he ignored the Old Testament clean laws in other ways, touching lepers and dead bodies.

But the reason is made clear. When he died on the cross the veil in the temple was ripped through, showing that the need for the entire sacrificial system with all its clean laws had been done away with. Jesus is the ultimate sacrifice for sin, and now Jesus makes us “clean.”

The entire book of Hebrews explains that the Old Testament ceremonial laws were not so much abolished as fulfilled by Christ. Whenever we pray ‘in Jesus name’, we ‘have confidence to enter the Most Holy Place by the blood of Jesus’ (Hebrews 10:19). It would, therefore, be deeply inconsistent with the teaching of the Bible as a whole if we were to continue to follow the ceremonial laws.
