The question is often raised about how Reformed ministers should dress in the pulpit. We have “Missional” pastors who will spend a fortune to affect a carefully arranged “grunge preacher” look, and then we have “high-church” reverends who prefer to look like the Reformed version of an Anglican Archbishop in the Pulpit. For myself, I tend to agree with Charles Spurgeon about dress. Incidentally you’ll find that although he was writing over a 100 years ago, he still managed to describe both the “Missional” and “High-Church” approaches to pastoral garb:
“When a man is proud as a peacock, all strut and show, he needs converting himself before he sets up to preach to others. The preacher who measures himself by his mirror may please a few silly girls, but neither God nor man will long put up with him. The man who owes his greatness to his tailor will find that needle and thread cannot long hold a fool in a pulpit. A gentleman should have more in his pocket than on his back, and a minister should have more in his inner man than on his outer man. I would say, if I might, to young ministers, do not preach in gloves, for cats in mittens catch no mice; don’t curl and oil your hair like dandies, for nobody cares to hear a peacock’s voice; don’t have your own pretty self in your mind at all, or nobody else will mind you. Away with gold rings, and chains, and jewelry; why should the pulpit become a goldsmith’s shop? Forever away with surplices and gowns and all those nursery doll dresses—men should put away childish things. A cross on the back is the sign of a devil in the heart; those who do as Rome does should go to Rome and show their colors. If priests suppose that they get the respect of honest men by their fine ornamental dresses, they are much mistaken, for it is commonly said, “Fine feathers make fine birds,” and
“An ape is never so like an ape
As when he wears a Popish cape.”
Among us dissenters the preacher claims no priestly power, and therefore should never wear a peculiar dress. Let fools wear fools’ caps and fools’ dresses, but men who make no claim to be fools should not put on fools’ clothes. None but a very silly sheep would wear wolf’s clothing. It is a singular taste which makes honest men covet the rags of thieves. Besides, where’s the good of such finery? Except a duck in pattens, no creature looks more stupid than a dissenting preacher in a gown which is of no manner of use to him. I could laugh till I held my sides when I see our doctors in gowns and bands, puffed out with their silks, and touched up with their little bibs, for they put me so much in mind of our old turkey when his temper is up, and he swells to his biggest. They must be weak folks indeed who want a man to dress like a woman before they can enjoy his sermon, and he who cannot preach without such milliner’s tawdry finery may be a man among geese, but he is a goose among men.
At the same time, the preacher should endeavor, according to his means, to dress himself respectably; and, as to neatness, he should be without spot, for kings should not have dirty footmen to wait at their table, and they who teach godliness should practice cleanliness. I should like white neckties better if they were always white, but dirty brown is neither here nor there. From a slovenly, smoking, snuff–taking, beer–drinking parson may the church be delivered. Some that I meet with may, perhaps, have very good manners, but they did not happen to have them about them at the time. Like the Dutch captain with his anchors, they had left them at home; this should never be the case, for, if there be a well–behaved man in the parish, it should he the minister. A worn coat is no discredit, but the poorest may be neat, and men should be scholars rather than teachers till they are so. You cannot judge a horse by its harness; but a modest, gentle–manly appearance, in which the dress is just such as nobody could make a remark upon, seems to me to be the right sort of thing.“

Who can speak so candidly today? This preacher would be accused of intolerance and bigotry. Mocking such a holy man as the pope! And that’s just from the PCA. After all, we just finished our Maundy Thursday, Good Friday, Easter celebrations. I am so sad.
