Is the mustard seed the smallest of seeds?

Alleged Biblical problem

In Matthew 13:31-32, Jesus said that the mustard seed was “smaller than all other seeds,” but that when it was full grown, it would be large enough for birds to nest in its branches.

Today, we know that there are seeds even smaller than the mustard seed. For instance, the orchid seed is so small and fine that it’s almost dust-like. There are those who would also question whether a mustard seed could ever grow into a tree that is large enough to hold a bird nest.

Now, if Jesus (who claimed to be God) was wrong about the mustard seed, why should we trust anything else that He said? And on what basis can the Bible be considered reliable on any scientific or historical matter?

Sensible solution

Please note that Jesus was not comparing the mustard seed to all other seeds in the world, but to seeds that a local, Palestinian farmer might have “sowed in his field,” i.e., a key qualifying phrase in verse 31. And it’s absolutely true that the black mustard seed (Brassica nigra = Sinapis nigra) was the smallest seed ever sown by a first-century farmer in that part of the world.

It’s also true, as many modern-day encyclopedias will tell you, that the black mustard seed in Israel will typically grow to heights of 3.7 meters, or 12 (twelve) feet—plenty large enough to hold a bird nest.

It’s important to remember that the Bible often uses everyday terminology in order to communicate simple truth. Even today, we might refer to a “sunset” when, technically, scientifically, we know that the sun never actually “sets,” i.e., it’s the Earth that revolves.

When people come to visit us here in north central Maine, we might take them on a drive, passing a good number of lakes and ponds, to Moosehead Lake, which I will describe to them as being “the largest lake of all.” Of course, our guests will usually realize that I’m speaking locally, not globally. They don’t often question my credibility.

The context of Matthew 13 makes it quite clear that Jesus was addressing a local lay audience, not an international conference of botanists. It seems that no reasonable person would therefore insist for very long that this text provides a viable basis for questioning either Jesus or the Bible, when it comes to getting the facts straight—scientifically, historically, or technically.
