Although, therefore, hypocrites and wicked men are members of this true Church according to outward rites [titles and offices], yet when the Church is defined, it is necessary to define that which is the living body of Christ, and which is in name and in fact the Church [which is called the body of Christ, and has fellowship not alone in outward signs, but has gifts in the heart, namely, the Holy Ghost and faith]. And for this there are many reasons. For it is necessary to understand what it is that principally makes us members, and that, living members, of the Church. If we will define the Church only as an outward polity of the good and wicked, men will not understand that the kingdom of Christ is righteousness of heart and the gift of the Holy Ghost [that the kingdom of Christ is spiritual, as nevertheless it is, that therein Christ inwardly rules, strengthens, and comforts hearts, and imparts the Holy Ghost and various spiritual gifts], but they will judge that it is only the outward observance of certain forms of worship and rites. Likewise, what difference will there be between the people of the Law and the Church if the Church is an outward polity? But Paul distinguishes the Church from the people of the Law thus, that the Church is a spiritual people, i.e., that it has been distinguished from the heathen not by civil rites [not in the polity and civil affairs], but that it is the true people of God, regenerated by the Holy Ghost. Among the people of the Law, apart from the promise of Christ, also the carnal seed [all those who by nature were born Jews and Abraham's seed] had promises concerning corporeal things, of government, etc. And because of these even the wicked among them were called the people of God, because God had separated this carnal seed from other nations by certain outward ordinances and promises; and yet, these wicked persons did not please God. But the Gospel [which is preached in the Church] brings not merely the shadow of eternal things, but the eternal things themselves, the Holy Ghost and righteousness, by which we are righteous before God. [But every true Christian is even here upon earth partaker of eternal blessings, even of eternal comfort, of eternal life, and of the Holy Ghost, and of righteousness which is from God, until he will be completely saved in the world to come.]
Therefore, only those are the people, according to the Gospel, who receive this promise of the Spirit. Besides, the Church is the kingdom of Christ, distinguished from the kingdom of the devil. It is certain, however, that the wicked are in the power of the devil, and members of the kingdom of the devil, as Paul teaches, Eph. 2, 2, when he says that the devil now worketh in the children of disobedience. And Christ says to the Pharisees, who certainly had outward fellowship with the Church, i.e., with the saints among the people of the Law (for they held office, sacrificed, and taught): Ye are of your father, the devil, John 8, 44. Therefore, the Church, which is truly the kingdom of Christ is properly the congregation of saints. For the wicked are ruled by the devil, and are captives of the devil; they are not ruled by the Spirit of Christ.
But what need is there of words in a manifest matter? [However, the adversaries contradict the plain truth.] If the Church, which is truly the kingdom of Christ, is distinguished from the kingdom of the devil, it follows necessarily that the wicked, since they are in the kingdom of the devil, are not the Church; although in this life, because the kingdom of Christ has not yet been revealed; they are mingled with the Church, and hold offices [as teachers, and other offices] in the Church. Neither are the wicked the kingdom of Christ, for the reason that the revelation has not yet been made. For that is always the kingdom which He quickens by His Spirit, whether it be revealed or be covered by the cross; just as He who has now been glorified is the same Christ who was before afflicted. And with this clearly agree the parables of Christ, who says, Matt. 13, 38, that the good seed are the children of the kingdom, but the tares are the children of the Wicked One. The field, He says, is the world, not the Church. Thus John [Matt. 3,12: He will throughly purge His floor, and gather His wheat into the garner; but He will burn up the chaff] speaks concerning the whole race of the Jews, and says that it will come to pass that the true Church will be separated from that people. Therefore, this passage is more against the adversaries than in favor of them, because it shows that the true and spiritual people is to be separated from the carnal people. Christ also speaks of the outward appearance of the Church when He says, Matt. 13, 47: The kingdom of heaven is like unto a net, likewise, to ten virgins; and He teaches that the Church has been covered by a multitude of evils, in order that this stumbling-block may not offend the pious; likewise, in order that we may know that the Word and Sacraments are efficacious even when administered by the wicked. And meanwhile He teaches that these godless men, although they have the fellowship of outward signs, are nevertheless not the true kingdom of Christ and members of Christ; for they are members of the kingdom of the devil. Neither, indeed, are we dreaming of a Platonic state, as some wickedly charge, but we say that this Church exists, namely, the truly believing and righteous men scattered throughout the whole world [We are speaking not of an imaginary Church, which is to be found nowhere; but we say and know certainly that this Church, wherein saints live, is and abides truly upon earth; namely, that some of God's children are here and there in all the world, in various kingdoms, islands, lands, and cities, from the rising of the sun to its setting, who have truly learned to know Christ and His Gospel.] And we add the marks: the pure doctrine of the Gospel [the ministry or the Gospel] and the Sacraments. And this Church is properly the pillar of the truth, 1 Tim. 3, 15. For it retains the pure Gospel, and, as Paul says, 1 Cor. 3, 11 [: "Other foundation can no man lay than that is laid, which is Jesus Christ">[, the foundation, i.e., the true knowledge of Christ and faith. Although among these [in the body which is built upon the true foundation, i.e., upon Christ and faith] there are also many weak persons, who build upon the foundation stubble that will perish, i.e., certain unprofitable opinions [some human thoughts and opinions], which, nevertheless, because they do not overthrow the foundation are both forgiven them and also corrected. And the writings of the holy Fathers testify that sometimes even they built stubble upon the foundation, but that this did not overthrow their faith. But most of those errors which our adversaries defend, overthrow faith, as, their condemnation of the article concerning the remission of sins, in which we say that the remission of sins is received by faith. Likewise it is a manifest and pernicious error when the adversaries teach that men merit the remission of sins by love to God, prior to grace. [In the place of Christ they set up their works, orders, masses, just as the Jews, the heathen, and the Turks intend to be saved by their works.] For this also is to remove "the foundation," i.e., Christ. Likewise, what need will there be of faith if the Sacraments justify ex opere operato, without a good disposition on the part of the one using them? [without faith. Now, a person that does not regard faith as necessary has already lost Christ. Again, they set up the worship of saints, call upon them instead of Christ, the Mediator, etc.] But just as the Church has the promise that it will always have the Holy Ghost, so it has also the threatenings that there will be wicked teachers and wolves. But that is the Church in the proper sense which has the Holy Ghost. Although wolves and wicked teachers become rampant [rage and do injury] in the Church, yet they are not properly the kingdom of Christ. Just as Lyra also testifies, when he says: The Church does not consist of men with respect to power, or ecclesiastical or secular dignity, because many princes and archbishops and others of lower rank have been found to have apostatized from the faith. Therefore, the Church consists of those persons in whom there is a true knowledge and confession of faith and truth. What else have we said in our Confession than what Lyra here says [in terms so clear that he could not have spoken more clearly]?
