The following was taken from a message given by John MacArthur at the Together for the Gospel Conference in 2006. I thought that it was funny so I figured that I would share it. If you're listening to the audio, it starts at 32:27.
One other note: Mac will say there are "three reasons…". Fear not if you missed the third (and even the second). He only says two, and the second was is only distinguished from the first by the words, "the other."
I hope that it edifies your souls, and makes you chuckle at the end.
"I think, I mean, this is arguable, I guess, but I think, maybe the most assaulted doctrine today is the headship of Christ over His Church. ... We say, 'Oh, what do you mean, "Christ is the Head of the Church"? We all know that; Colossians 1, Ephesians 1 - we all know that. Isn't that a little benign to us?' Do you know, that doctrine has sailed down to us on a sea of blood? You know how many people have been massacred over that issue? ... In the conflict between the Reformers and the Roman Catholics about who is the Head of the Church, Roman Catholicism still says the pope is the Head of the Church, and if you deny that, you're anathema. Take the covenanters, they fought the battle, lost their lives, over whether the king or queen, or the pope (when there was a Catholic monarchy) is the Head of the Church. Today, we've got a whole bunch of little heads of their churches popping up all over everywhere, who, in effect, have produced a mutiny against the true Head of the Church by taking the Word of the Head of the Church out of the Church, and silenced Him. You take the Bible out of the Church, you take the Word of the Head of the Church, away from the Church, and you have carried off a revolution. When you bring to the people the mind of Christ, contained in the Word of God, you exalt the headship of Christ over His Church. At [the] Ligonier Conference I talked about this, and went back to Jan Hus. He was July 6th, 1415 burned at the stake. And there were basically three reasons they burned him at the stake. It's really an incredible story. They burned him at the stake, one, because he said the true Church is made up of all predestined believers. That doesn't sound too revolutionary. Not unless you accept the Catholic view at the time. The true Church is the pope, the cardinals, the bishops, the priests, period. And the only way that lay people communed with the Church is through the wafer. Well, Hus was in agreement with Wycliffe, that all predestined believers are the Church. This was unacceptable to them - absolutely unacceptable. And the other big issue was that he said that the pope was not the Head of the Church. And for that he was burned at the stake. R.C. Sproul told me an interesting story, a little bit of a history. When Hus was burned at the stake, you remember he was called 'the Goose,' he was from Husinec, but he shortened it to Hus 'the Goose,' that's where we get the phrase, 'The goose was cooked.' ... But when Hus was being martyred, he made the statement that, 'You could kill me,' (something like this) 'but there will come another after me, that you will not be able to silence.' Well, that was a hundred years later, exactly, that was Martin Luther. Luther was rummaging around in a library, and found a whole bunch of papers of Hus's sermons. And he found Hus to be a pre-Reformation Reformer, who was dealing with the same doctrinal issues and even Hus came out strongly against Indulgences. So Luther found a real partner. That's why some paintings of Luther, you'll find a goose in the background, because Hus was like a hero. Hus was sentenced to die by the Bishop of the Council of Constance and he died in the flames, singing psalms. A hundred years later Luther comes along, reads his sermons, picks up on it, he's a hero, even adapts the idea of being a goose. Luther is the fulfillment, in a sense, of that prophecy, 'One will come after me, that you will not be able to silence.' Curious note, R.C. Sproul told me, Luther was ordained at Erfurt, and when you were ordained in those days you had to lay, on the ground, flat on the floor, below the altar, with your arms spread ... in the sign of a cross. And Luther was lying there in that position when he was ordained, and he was lying on a crypt. And the crypt was the crypt of the Bishop of Constance who had condemned Hus to death. And R.C. Sproul imagines that when Hus said, 'You may silence me but there will come one after me you will not silence,' that maybe the Bishop of Constance said, 'Over my dead body.' Maybe, maybe."
