to express them, must he be recognized as a heretic, if he is not able precisely to express his ideas? And is not this true, that in the early times there was no heresy, because the Christians did not judge one another according to verbal expressions, but according to the heart and acts, in connection with a complete liberty of expression, without fear of being recognized as a heretic? Was it not a very common and easy method with the church,” he says in Question 21, “when the clergy wanted to get rid of a person or ruin him, to make him suspected as regards his doctrine and to throw over him the cloak of heresy, and thus to condemn and remove him?
“Though it is true that amidst the so-called heretics there were errors and sins, yet it is not less true and obvious from the numberless examples here adduced” (that is, in the history of the church and of heresy), he says farther on, “that there has not been a single sincere and conscientious man with some standing who has not been ruined by the churchmen out of envy or for other causes.”
Thus, nearly two hundred years ago, was the significance of heresy understood, and yet this conception continues to exist until the present time. Nor can it fail to exist, so long as there is a concept of the church. Heresy is the flip-side of the church. Where there is the church, there is also heresy. The church is an assembly of men asserting that they are in possession of the indisputable truth. Heresy is the opinion of people who do not recognize the indisputableness of the church truth.
Heresy is a manifestation of motion in the church, an attempt at destroying the ossified assertion of the church, an attempt at a living comprehension of the teaching. Every step of moving forward, of comprehending and fulfilling the teaching has been accomplished by the heretics: such heretics were Tertullian, and Origen, and Augustine, and Luther, and Huss, and Savonarola, and Chelčický and others. Nor could it be otherwise.
