Not so very long ago the pharmacy and the pantry were one and the same. Curatives and restoratives were cooked up at home, not picked up at the drug store. It is hard for us to realize that 1914 was really the first year when a trip to the doctor made you better.

Long before scientific discoveries revealed the inner workings of penicillin, digitalis, or even aspirin, old wives and herbologists prescribed moldy bread for coughs, supplied foxglove for the faint-hearted, and urged headache sufferers to chew wintergreen leaves. But one of the most popular and widely used cures was the old-fashioned mustard plaster.

Anybody ever seen one? [If you can put one together to show them, great!]

Anybody ever even heard of one?

Here's how it was done. 1. Mustard flour was mixed into a paste. 2. Then the paste was liberally slathered onto a moistened cloth. 3. The plaster was then laid on the patient's skin to help drive out the afflicting agent.

Mustard plasters could be applied to the stomach, back, chest, kidneys, all stiff and sore joints, and the head. As a stimulant, the ground mustard in the compress would increase the blood supply to the affected area, allowing the body to work more efficiently at carrying away toxins, speeding digestion, easing sore muscles, and generally accelerating the body's own healing abilities. Fevers broke, lungs cleared, headaches subsided, muscle cramps ceased...when a good strong mustard plaster was applied.

Today we have relegated mustard to the door-rack of our refrigerators. [Here is where you need some samples. If you can get everyone in your congregation a mustard packet, great. But try and have some various kinds of mustard bottles up front to show your people and to squirt out and lather on hot-dogs, etc.] We squirt the bright-yellow kind on our hot dogs and ham sandwiches without even considering that the condiment is probably the only healthy component of those meals.

More sophisticated palates go for the browner, seedier mustards ("I say...have you any Grey Poupon?"). But except among a few knowledgeable chefs, mustard's subtleties and strengths are virtually disregarded. Mustard is such a common, everyday, ordinary ingredient that it doesn't even register.

But Jesus saw differently. Jesus knew better. For Jesus mustard presented a perfect picture of the kingdom of God and the faith of those who would reside there.

It is no accident that Jesus picks the mustard seed in today's example of faithfulness (Luke 17:5-6) as well as in his parable of the kingdom of Heaven (Mt. 13:31-32). Its reputation for being proverbially (though not actually) the smallest of seeds, creates a wonderful image for the Kingdom and its growth into a large-size structure. Luke's gospel captures mustard's tiny, seed-sized faith that is capable of accomplishing miraculous feats.

Just as there were seeds smaller in Jesus' culture than the mustard seed, there were trees known to be larger than the mustard shrub. Everyone knew the oak and the cedar were bigger. So why doesn't Jesus compare the acorn or the cone to a small faith that achieves great things.

Why the mustard shrub rather than the mighty cedar of Lebanon? Or the great oak of Bashan?

Jesus tells us that in being salt to the world, we are to bring zing and zest to the lives of others through our dealings with them. But isn't that also true of mustard, whose seed Jesus says is our seed of faith and the kingdom seed?

Surely the sharp, pungent spiciness of mustard adds zest and flavor to anything to which this condiment comes into contact. Mustard makes the juices flow and our mouth water. Mustard is alive, bursting with flavor and color. Mustard is never neutral or lukewarm like Laodicea. The Biblical Illustrator for Mark 4:32 recounts that Darius sent Alexander the Great a bag of sesame seed to symbolize the vast number of his army. In return, Alexander sent back a sack of mustard seed, showing not only the number but the fiery energy of his soldiers.

The apostles have the wrong quality in mind when they implore Jesus to increase their faith. Faith is not about quantity. Faith is about quality. Faith is not about size. Faith is about spice.

The tiny mustard seed reveals its strength when it is bitten into – it bites back!

Like us the apostles thought "bigger is better." But more of their show-me/give-me/do-for-me faith would still have left these apostles stuck at the starting line. The apostles were convinced that faith was a possession that would move them up a notch in God's eyes and in the hierarchy of heaven.

Jesus' tiny mustard-seed sized faith doesn't advance the faithful one bit. But it does transform reality. It transplants living trees into the middle of the sea. Jesus' mustard seed faith has more than mindless muscle power. It has mouthwatering, eye-watering piquancy.

Small size...big kick. And for his listening apostles this kick is delivered to the seat of their pants. How foolish of them (and us) to think that their paltry faithfulness earns them privileges from God, a lofty place in the kingdom. The truth is that as obedient, faithful servants of the kingdom all disciples owe God nothing more than all their devotion, all their labor, all of their life.

Jesus' choice of the mustard seed also points up another discipling quality that we self-centered followers like these self-obsessed apostles forget to consider. Mustard is not to be eaten alone. It is as its best when doing what it is created for: helping something else achieve its true and greatest potential. Some things just cry out for their proper accompaniment. Peanut butter and...jelly; hot dogs and...mustard; life and...faith.

Though mustard's seasoning and zest is something we receive through our living, Jesus also wants us to possess and practice mustard's healing qualities. For us not to recognize that Jesus meant to include healing, not just size and spice, as part of mustard's – and faith's – identity is like not associating Microsoft with the Internet. In Jesus' day, indeed up until our great-grandparents day, mustard meant healing, not hot dogs.

This is the philosopher Pliny the Elder (as quoted by biblical scholar Bernard Brandon Scott in Hear Then the Parable): Pythagoras judged [mustard] to be chief of those whose pungent properties reach a high level, since no other penetrates further into the nostrils and brain. Pounded it is applied with vinegar to the bites of serpents and scorpion stings. It counteracts the poisons of fungi. For phlegm, it is kept in the mouth until it melts, or is used as a gargle with hydromel. For toothache it is chewed...It is very beneficial for all stomach troubles...It clears the senses, and by the sneezing caused by it, the head; it relaxes the bowels, it promotes menstruation and urine.

Another early theologian of the church Clement of Alexandria wrote that mustard "represses bile (anger) and checks inflammation (pride)". (see the Ancient Christian Commentary on Scripture, II, Mark). Maybe our great-grandmothers knew what they were talking about when they prescribed mustard plasters for chest colds.

Scott writes further that "Pliny then goes on to explain how in combination with other things it cures many other illnesses. From his description there appears to be no illness that mustard will not cure."

Curing illnesses. HMMMM.

Didn't Jesus do that? Doesn't Revelation talk about no more diseases?

Jesus tells us that in being salt to the world, we are to embody salt's preservative qualities. In being light to the world, we help bring revelation and wholeness to those in the world through Christ. In being mustard to the world, we not only enliven it, but we bring mustard's healing propensities to it, and help create preservation and promote wholeness.

The mustard seed "resists infection and adversity." (Clement of Alexandria, as quoted in Ancient Christian Commentary, II, Mark 4:30-34). In being like mustard, we through faith in Christ resist infection and adversity as well.

Mustard enhances our own soul in addition to enhancing the life of the world. It's healing qualities, through the kingdom it represents, will help heal our illnesses as well as the world's.

Jesus said we are to be salt and light to the world.

And mustard. Don't forget the mustard.

Jesus' parable about the mustard seed reminds us that we are to be to the world what mustard is to the hot dog-pungency and power.

Will you be this week the mustard of the earth...a kick in the pants and an arm around the shoulder of those in need?

(Consider having a hot dog stand after church where people are invited to squirt mustard or slather mustard on a hot dog from a bright yellow container that says not "French's mustard" but "God's mustard")
