I find it frustrating when I read or hear columnists, pundits or journalists dismiss Christians as inconsistent because “they pick and choose which of the rules in the Bible to obey.”
What I hear most often is, “Christians ignore lots of Old Testament texts—about not eating raw meat or pork or shellfish, not executing people for breaking the Sabbath, not wearing garments woven with two kinds of material and so on. Then they condemn homosexuality. Aren’t they just picking and choosing what they want to believe from the Bible?”
It is not that I expect everyone to have the capability of understanding that the whole Bible is about Jesus and God’s plan to redeem his people, but I vainly hope that one day someone will access their common sense (or at least talk to an informed theological advisor) before leveling the charge of inconsistency.
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.
