He died (on this day eight decades ago).
Machen’s reasons for being a critic of the PCUSA — to the point that some thought he was impossible and failed to show Christian charity — were clear in his testimony before the Presbytery of New Brunswick (you know, the one that the Synod of Philadelphia created to make the revivalists feel welcome), the body that tried, found him guilty, and excommunicated him from the mainline church:
Suppose a minister obtains his ordination by promising to support the boards and agencies, as he is required to do by the plain intent of that addition to the manual of the Presbytery of New Brunswick and by the plain intent of the action of the 1934 General Assembly. Suppose he later becomes convinced that the boards and agencies are unfaithful to their trust. Let us even take an extreme case. Let us suppose that he has become convinced that those in charge of the boards and agencies are guilty of actual embezzlement. That case, is, of course, entirely hypothetical, but an extreme case does illustrate plainly the principle that is involved. Let us insist upon putting that extreme case. Here is a minister who has promised that he will, as long as he remains a minister in the Presbyterian Church in the U.S.A., support the boards and agencies as they are established by successive General Assemblies. He he has become convinced that those boards and agencies are positively dishonest, even with the kind of dishonestly that is contrary to the criminal laws of the land.
What course of action is open to such a minister? He is convinced that the boards and agencies are dishonest. The general assembly is convinced that they are honest. What shall he do in such a situation? . . . Only two courses of action are open to a minister who is in such a quandary.
In the first place, he may continue to support boards and agencies which he holds to be dishonest. That course of action would plainly involve him in dishonesty. An honest man cannot possibly recommend to people that they should give to agencies which he hold to be dishonest.
In the second place, a minister who is in such a quandary may withdraw from the Presbyterian Church in the U.S.A. That plainly means evasion of the solemn responsibility which he has as a minister. I really wonder whether those who advocate this action of the General Assembly have ever thought this thing through. Do they really mean to tell us that just because a majority in the General Assembly has made a mistake one year and has placed in charge of the missionary funds of the church men who are dishonest, therefore a minister should withdraw from the church and allow that dishonesty to go on? I say that such conduct is an evasion of a solemn responsibility. No, it is the duty of a minister in such a situation to remain in the church and to seek by every means in his power to bring about a change in that policy of the General Assembly which he regards as involving dishonest. Meanwhile (and this should be particularly observed), he cannot for any consideration whatever give a penny to what he regards, rightly or wrongly, to be a dishonest agency; and still less can he recommend to any other persons the support of such an agency. . . .
I could never promise to support any human agency as a condition of my being ordained. I could not promise to support the Independent Board for Presbyterian Foreign Missions, which I believe now to be sound in the faith. . . . It is at the very heart and core of my ordination pledge, in accordance with the law of the Presbyterian church, that I should repeatedly examine any agency that appeals to me for support in the light of the Word of God, and support it only if it is in accord with that blessed Word. Moreover, in determining whether it is in accord with that Word, I must be governed by my conscience, as God may give me light, and not by the pronouncements of any human councils or courts.
If that is contrary to Presbyterian law, then I should certainly be removed from the Presbyterian Church in the U.S.A. But all the glorious history of the Reformed faith should teach a man if the Word of God does not teach him, that it is not contrary to Presbyterian law but is at the very heart of Presbyterian law.
