It is in this wise, and never in any other, that the Holy
Scriptures speak of the Holy Church and of Christendom.
[Sidneote: The External Church]
Beyond that, another way of speaking of Christendom has come into use. According to this, the name Church[36] is given to an assembly in a house or a parish, a bishopric, an archbishopric, or the papacy, in which assembly external rites are in use, such as chanting, reading, vestments. And primarily the name of "spiritual estate" is given to the bishops, priests and members of the holy orders; not on account of their faith, which they perhaps do not have, but because they have been consecrated with an external anointing, wear crowns, use a distinctive garb, make special prayers and do special works, say mass, have their places in the choir, and attend to all such external matters of worship. But violence is done to the word "spiritual," or "Church," when it is used for such external affairs, whereas it concerns faith alone, which, working in the soul, makes right and true spirituales and Christians; yet this maimer of using it has spread everywhere, to the great injury and perversion of many souls, who think that such outward show is the spiritual and only true estate in Christendom or the Church.
There is not one letter in the Holy Scriptures to show that such a purely external Church has been established by God; and I hereby challenge all those who have made this blasphemous, damnable, heretical book, or would defend it, together with all their followers, even if all the universities hold with them. If they can show me that even one letter of the Scriptures speaks of it, I am willing to recant. But I know that they cannot do it. The Canon Law and human statutes, indeed, give the name of Church or Christendom to such a thing, but that is not now before us. Therefore, for the sake of brevity and a better understanding, we shall call the two churches by different names. The first, which is the natural, essential, real and true one, let us call a spiritual, inner Christendom. The other, which is man-made and external, let us call a bodily, external Christendom: not as if we would part them asunder, but just as when I speak of a man, and call him, according to the soul, a spiritual, according to the body, a physical, man; or as the Apostle is wont to speak of the inner and of the outward man. [Rom. 7:22] Thus also the Christian assembly, according to the soul, is a communion[37] of one accord in one faith, although according to the body it cannot be assembled at one place, and yet every group is assembled in its own place. This Christendom is ruled by Canon Law and the prelates of the Church.[38] To this belong all the popes, cardinals, bishops, prelates, monks, nuns and all those who in these external things are taken to be Christians, whether they are truly Christians at heart or not. For though membership in this communion[37] does not make true Christians, because all the orders mentioned may exist without faith; nevertheless this communion is never without some who at the same time are true Christians, just as the body does not give the soul its life, and yet the soul lives in the body and, indeed, can live without the body. Those who are without faith and are outside of the first community, but are included in this second community, are dead in the sight of God, hypocrites, and but like wooden images of true Christians. And so the people of Israel were a type of the spiritual people, assembled in faith.
[Sidenote: The Church as a Building]
The third use of the term applies the word Church, not to Christendom, but to the edifices erected for purposes of worship. And the word "spiritual" is so stretched as to cover temporal possessions, not the possessions which are truly spiritual because of faith, but those which are in the second or external Church,[39] and such possessions are called "spiritual" or Church possessions.[40] Again, the possessions of the laity are called "worldly," although the laymen who are in the first or spiritual Church[39] are much better than the worldly clergy and are truly spiritual. After this fashion it now goes with almost all the works and the government of the Church;[39] and the name "spiritual possessions" has been so exclusively applied to worldly possessions that now no one understands it to mean anything else, and this has gone so far that men regard neither the spiritual nor the external Church any more, and they squabble and quarrel about temporal possessions like the heathen, and say, they do it for the sake of the Church and of spiritual possessions. Such perversion and misuse of words and things has come from the Canon Law and human statutes, to the unspeakable corruption of Christendom.
[Sidneote: The Head of the Church: Christ]
Now let us consider the head of Christendom. From the foregoing it follows that the first-named Christendom, which alone is the true Church, may not and cannot have Church: a head upon earth, and that no one on earth, neither bishop nor pope, can rule over it; only Christ in heaven is the head, and He ruleth alone.
[Sidenote: Why the Church Cannot Have an Earthly Head]
This is proved, first of all, in this way: How can a man rule over anything which he does not know or understand? And who can know whether a man truly believes or not? Aye, if the power of the pope extended to this point, then he could take away a Christian's faith, or direct its progress, or increase it, or change it, according to his pleasure, just as Christ can do.
