You will have a battle, too, when you go forth as ministers into the church. The church is now in a period of deadly conflict. The redemptive religion known as Christianity is contending, in our own Presbyterian Church and in all the larger churches in the world, against a totally alien type of religion. As always, the enemy conceals his most dangerous assaults under pious phrases and half truths. The shibboleths of the adversary have sometimes a very deceptive sound. “Let us propagate Christianity,” the adversary says, “but let us not always be engaged in arguing in defense of it; let us make our preaching positive, and not negative; let us avoid controversy; let us hold to a Person and not to dogma; let us sink small doctrinal differences and seek the unity of the church of Christ; let us drop doctrinal accretions and interpret Christ for ourselves; let us look for our knowledge of Christ in our hearts; let us not impose Western creeds on the Eastern mind; let us be tolerant of opposing views.” Such are some of the shibboleths of that agnostic Modernism which is the deadliest enemy of the Christian religion to-day. They deceive some of God’s people some of the time; they are heard sometimes from the lips of good Christian people, who have not the slightest inkling of what they mean. But their true meaning, to thinking men, is becoming increasingly clear. Increasingly it is becoming necessary for a man to decide whether he is going to stand or not to stand for the Lord Jesus Christ as he is presented to us in the Word of God.
If you decide to stand for Christ, you will not have an easy life in the ministry. Of course, you may try to evade the conflict. All men will speak well of you if, after preaching no matter how unpopular a Gospel on Sunday, you will only vote against that Gospel in the councils of the church the next day; you will graciously be permitted to believe in supernatural Christianity all you please if you will only act as though you did not believe in it, if you will only make common cause with its opponents. Such is the program that will win the favor of the church. A man may believe what he pleases, provided he does not believe anything strongly enough to risk his life on it and fight for it. “Tolerance” is the great word. Men even ask for tolerance when they look to God in prayer. But how can any Christian possibly pray such a prayer as that? What a terrible prayer it is, how full of disloyalty to the Lord Jesus Christ! There is a sense, of course, in which tolerance is a virtue. If by it you mean tolerance on the part of the state, the forbearance of majorities toward minorities, the resolute rejection of any measures of physical compulsion in propagating either what is true or what is false, then of course, the Christian ought to favor tolerance with all his might and main, and ought to lament the widespread growth of intolerance in America today. Or if you mean by tolerance forbearance toward personal attacks upon yourself, or courtesy and patience and fairness in dealing with all errors of whatever kind, then again tolerance is a virtue. But to pray for tolerance apart from such qualifications, in particular to pray for tolerance without careful definition of that of which you are to be tolerant, is just to pray for the breakdown of the Christian religion; for the Christian religion is intolerant to the core. There lies the whole offense of the Cross—and also the whole power of it. Always the Gospel would have been received with favor by the world IF it had been presented merely as one way of salvation; the offense came because it was presented as the only way, and because it made relentless war upon all other ways. God save us, then, from this “tolerance” of which we hear so much : God deliver us from the sin of making common cause with those who deny or ignore the blessed Gospel of Jesus Christ! God save us from the deadly guilt of consenting to the presence as our representatives in the church of those who lead Christ’s little ones astray; God make us, whatever else we are, just faithful messengers, who present, without fear or favor, not our word, but the Word of God.
